Excavator Hydraulic Pump Manufacturers: 10 Compared

By GW · Last updated: October 2026

Excavator hydraulic pump manufacturers to shortlist include Kawasaki for excavator-specific piston pumps, Bosch Rexroth for electronic controls, Doosan Mottrol for tandem and compact units, and Casappa for mini and midi applications. The best choice starts with the pump’s circuit role and full assembly code. A familiar brand alone doesn’t establish replacement compatibility.

Quick picks for excavator pump sourcing

Six application-based sourcing routes, from Kawasaki excavator families to Casappa mini/midi (maker product pages).

Best for excavator-specific families: Kawasaki Precision Machinery.
Best for electronic system controls: Bosch Rexroth.
Best for tandem and compact alternatives: Doosan Mottrol.
Best for mini and midi application coverage: Casappa.
Best for open/closed-circuit portfolio comparison: LHY Powertrain.
Best for distributor configuration programs: Parker Hannifin.

Disclosure: LH Used Excavator publishes this guide for equipment buyers. Manufacturers are grouped by pump application and support route; this listing isn’t a market-share index.

How we selected these hydraulic pump manufacturers

Documented pump manufacturing and application evidence define inclusion; this is not a market-share ranking.

We researched and identified manufacturers with documented hydraulic pump product lines and a company history, isolating excavator-specific products from broader mobile hydraulics. Company information and product applications were verified against company websites and public sources in October 2026. Directories, marketplaces, brokers without documented manufacturing, and complete-machine sellers without documented pump production were excluded. Enumeration doesn’t indicate quality or output, and doesn’t reflect ranking. Selection criteria: documented pump manufacturing and relevant application evidence.

Main, mini and pilot pump applications

Gear, vane and piston are separate pump types (Portland Community College hydraulic fundamentals).

An excavator’s main implement, final drive and the pilot circuits have different functions. An open-circuit main pump isn’t automatically interchangeable with a closed-circuit drive unit. Compact machines can use combinations of piston and gear sections. The variety of hydraulic pumps offered by these major brands serves various applications; compare function before displacement or flow rates.

What are the three main types of hydraulic pumps?

Gear pumps, vane pumps and piston pumps are three common types; piston designs include axial and radial piston arrangements. Gear and vane pumps are taught at Portland Community College’s Caterpillar hydraulic fundamentals course. For excavator sourcing, the machine’s hydraulic system determines which design and control arrangement belongs in each circuit.

Main-pump and control-system manufacturers

Layout, electronics, circuit, interfaces and service route distinguish main-pump sourcing (maker catalogs).

1. Kawasaki Precision Machinery: Best for excavator-specific pump families

Headquarters: Tokyo and Kobe, Japan, for parent Kawasaki Heavy Industries · Founded: parent incorporated in 1896 · Type: hydraulic pump and control manufacturer.

Official website: https://www.kawasakihydraulics.com/

Main products: K3V, K5V and K7V axial piston pumps. Capabilities: 63–212 cc options and a published 350 bar continuous rating.

Kawasaki describes this range specifically for hydraulic excavators and other mobile machinery, giving buyers a direct application starting point. Single, tandem and parallel arrangements, together with power, pressure and displacement controls, provide several configuration routes. Those layouts are different assemblies, so the family name alone isn’t a replacement part number.

2. Bosch Rexroth: Best for electronically controlled hydraulic systems

Headquarters: Lohr am Main, Germany · Founded: Bosch Rexroth combination in 2001; Rexroth roots in 1795 · Type: drive, control and component manufacturer.

Official website: https://www.boschrexroth.com/

Main products: A10VO Series 60 and eOC architecture. Capabilities: nominal pressure up to 280 bar; electronic and classic DRS versions.

Rexroth’s eOC system combines pump sensors, CAN communication and software control; its application examples include a compact excavator. That system approach suits equipment development where pump behavior and machine controls are specified together. BODAS or compatible third-party controllers form part of the architecture. An eOC unit therefore brings sensor and software requirements that differ from a classic DRS-controlled pump, even when the product family appears similar.

3. LHY Powertrain: Best for comparing open and closed circuits

Headquarters: Aschaffenburg, Germany · Founded: independent entity in 2012, with roots in 1904 · Type: hydraulic component and system manufacturer, formerly Linde Hydraulics.

Official website: https://lhy.com/

Main products: HPR-02 open-circuit and HPV-02 closed-circuit pumps. Capabilities: self-regulating, double, tandem and multiple units with mechanical, hydraulic or electric inputs.

The company’s history records the change to LHY Powertrain in 2025, relevant when older machinery carries Linde identification. This range of hydraulic solutions separates circuit architecture and offers torque control and pressure cutoff options. Multiple-unit arrangements help explain why configuration matters more than the brand stamped on a casting. HPR and HPV serve different circuit architectures; their names shouldn’t be treated as equivalent replacement choices.

4. Hengli Hydraulic: Best for documented mounting and control options

Headquarters: Changzhou, China · Founded: 1990 · Type: integrated hydraulic component and system manufacturer.

Official website: https://www.henglihydraulics.com/

Main products: HP3V variable axial piston pumps, valves, motors and cylinders. Capabilities: the published 140 cc/rev model is rated at 350 bar, with SAE and JIS shaft and flange alternatives.

Hengli’s HP3V page describes an open-circuit swashplate pump with several control options and optional through drive. Those details give a procurement team concrete interface choices when comparing a complete hydraulic package. A through-drive option also matters when another pump section forms part of the assembly. SAE and JIS mounting and shaft alternatives require a specific interface selection; equal nominal displacement doesn’t make those versions mechanically identical.

5. Liebherr Machines Bulle: Best for double-pump architecture

Headquarters: Bulle, Switzerland · Founded: Liebherr Machines Bulle SA in 1978 · Type: hydraulic pump, motor and drive-component manufacturer within Liebherr.

Official website: https://www.liebherr.com/

Main products: DPVD variable double axial piston pumps. Capabilities: back-to-back construction with a common suction port; listed displacement variants include 107.7, 167.8 and 550 cm³.

DPVD’s layout helps buyers compare packaging and suction connections. Liebherr also describes a component Reman program. For spare parts on an existing Liebherr machine, however, the company directs requests to the local service partner, making that service channel part of the purchasing route.

Compact and broader mobile-hydraulics manufacturers

Drive duty and controller integration distinguish five mobile pump sourcing routes (manufacturer catalogs).

6. KYB Corporation: Best for construction hydraulic component packages

Headquarters: Tokyo, Japan · Founded: roots in 1919; established 1935 and incorporated 1948 · Type: hydraulic and motion-control component manufacturer.

Official website: https://www.kyb.co.jp/

Main products: construction-machinery piston pumps, control valves, travel motors and swing motors. Capabilities: high-pressure pumps and electronically compatible closed-circuit drive pumps.

KYB’s construction range spans the pump, actuator and control sides of machinery, including cylinders and shovel control valves. This breadth makes it relevant when comparing coordinated hydraulic components rather than an isolated listing. The range also distinguishes closed-circuit drive applications. A drive pump serves a different function from an open-circuit implement pump, so membership in the construction equipment range doesn’t establish an excavator main-pump cross-reference.

7. Doosan Mottrol: Best for tandem and compact duplex pump options

Headquarters: Changwon, South Korea · Founded: 1974; excavator pump production began in 1990 · Type: hydraulic pump, motor and valve manufacturer.

Official website: https://www.doosanmottrol.com/

Main products: DPA and DPB tandem pumps, DPS compact duplex pumps, travel and swing motors. Capabilities: negative-flow, positive-flow and electric control options on DPA; DPS20 applications include 2.5–3.5 t excavators.

Mottrol gives buyers both an excavator production history and named product families to investigate. DPA control alternatives help distinguish assemblies that may look similar externally but respond differently to machine commands. The compact DPS design serves another size class and combines pump sections in one package. DPA tandem and DPS compact duplex units therefore represent different machine classes and control arrangements, rather than interchangeable versions of one pump.

8. Parker Hannifin: Best for distributor build and configuration programs

Headquarters: Cleveland, Ohio, USA · Founded: business origin in 1917; incorporated 1938 · Type: motion-control and hydraulic component manufacturer.

Official website: https://www.parker.com/

Main products: P2/P3 high-pressure mobile pumps, P1/PD and PVplus pumps. Capabilities: authorized distributor build and conversion programs covering these families.

Parker’s published program provides a route for configuring hydraulic components through participating distributors. Its family coverage is useful when an equipment builder or repair business needs to discuss pump configuration and local support together. The program identifies product families rather than promising compatibility with every heavy equipment model. This broad mobile portfolio needs an engineered application match; it isn’t a universal excavator replacement catalogue.

9. Danfoss Power Solutions: Best for high-power open-circuit options

Headquarters: Nordborg, Denmark, for the Danfoss parent group · Founded: parent group in 1933 · Type: mobile hydraulic pump and control manufacturer.

Official website: https://www.danfoss.com/

Main products: D1P open-circuit axial piston pumps. Capabilities: displacement up to 260 cm³, 350 bar maximum working pressure, and MTC or EDC controls.

Danfoss PowerSource explicitly includes excavators among D1P applications, giving this selection a documented machine category. Mechanical torque control and electronic displacement control offer distinct ways of managing the pump, useful when comparing an existing control arrangement with a proposed unit. Published maxima describe the family rather than every configuration. MTC and EDC versions need different machine controls, so choosing larger displacement alone doesn’t resolve integration.

10. Casappa: Best for mini and midi excavator application coverage

Headquarters: Lemignano di Collecchio, Parma, Italy · Founded: hydraulic pump business origin in 1952 · Type: pump, motor and electronic-control manufacturer.

Official website: https://www.casappa.com/

Main products: MVP, MVPD, MVPe and PLATA variable piston pumps, plus gear pumps. Capabilities: open-circuit designs with pressure, load-sensing, torque and electronic controls.

Casappa lists mini and midi excavators among its applications, making it a relevant compact-machine candidate. MVPe combines a piston pump, angle sensor, electronic pressure compensator and ECU; that package illustrates how pump sourcing can extend into machine electronics. The wider range offers several control routes rather than one standard assembly. MVPe’s integrated electronics make it a different integration task from a purely hydromechanical pump, even within the same supplier’s portfolio.

How to choose a pump and supplier

Match identity, circuit, interfaces, controls, condition, test evidence and support before comparing pump quotes.

How to Choose the Best Excavator Hydraulic Pump?

Start with the full pump identification and machine serial number, then match OEM specifications for the circuit, mechanical interfaces and controls. Compare supply conditions and after-sales services only after matching the circuit, mechanical interfaces and controls. A quotation for the same assembly and condition is more valuable than a low price that’s tied to a similar casting.

Identity: Collect the complete part number, suffixes and nameplate photographs.
Circuit: distinguish implement, pilot and drive duties.
Interfaces: compare shaft, mounting, rotation, ports and through drive.
Controls: match regulator type, command signals and controller requirements.
Condition: separate genuine new, aftermarket replacement and remanufactured offers.
Evidence: request a unit-specific report from hydraulic test benches with stated conditions, traceability and applicable certification scope.
Support: compare written warranty on core components, core return, freight and service responsibilities.

A machine’s sluggish operation or tendency to overheat is not itself a pump diagnosis. Use a qualified hydraulic technician before committing to replacement. In the case of purchasing the whole machine, our used excavator inspection checklist can help assess condition and organize key points for comparison.

For the construction industry, an equipment upgrade should improve a defined machine function. Hydraulic performance and service life affect operating costs, while contamination and accelerated wear can undermine uptime after replacement. Owners comparing international brands available for demanding construction environments should request the same shaft, mounting, rotation, port and regulator-control checks. Precision machining of a replacement housing does not establish control compatibility. A claim of high-performance hydraulic pumps should state rated pressure and input speed at the selected displacement and inlet conditions; quality hydraulic work should begin with a documented match of ports and controls, including on heavy-duty wheeled excavators.

Frequently asked questions

Which manufacturers make excavator main hydraulic pumps?

Kawasaki and Doosan Mottrol document excavator pump families; Danfoss lists excavators among D1P applications.

Kawasaki’s K3V/K5V/K7V range is explicitly intended for hydraulic excavators and mobile machinery. Mottrol publishes DPA tandem families and a production history for excavator pumps. Danfoss identifies D1P as an open-circuit option with excavator applications. These are useful manufacturer starting points, while the complete machine and pump codes determine the actual replacement assembly.

Which hydraulic pump brands suit mini excavators?

Casappa, Doosan Mottrol and Bosch Rexroth provide documented compact-machine application examples.

Casappa’s applications include mini and midi excavators. Mottrol specifies the DPS20 for a 2.5–3.5 t class, while Rexroth describes a compact-excavator eOC application. Each example establishes an application category rather than universal fitment. A small gear section and a compact duplex piston assembly can perform different duties on machines of similar size.

Should I choose genuine new, aftermarket or remanufactured?

Compare all three only when assembly identity, condition and warranty responsibilities are clearly stated.

Genuine new follows the machine or component maker’s identified supply route. Aftermarket means a replacement from another supply source, without automatically proving equal specifications. Remanufactured condition needs its own documented scope. Rexroth, for example, describes repair to original specifications and a 12-month warranty on replaced parts; that wording isn’t a blanket warranty for every rebuilt pump.

Is an excavator brand the same as the pump manufacturer?

No. The machine brand and the component producer can be different companies.

A Komatsu, Volvo or Hitachi machine name identifies the carrier. It doesn’t by itself identify the pump maker, regulator revision or replacement specification.

How much does an excavator hydraulic pump cost?

One current example is Bobcat gear pump 7349884REM at $1,652.49 plus a $450 refundable core charge, checked in October 2026.

This is one remanufactured gear-pump SKU, not a price range for tandem main pumps. The listing’s total before tax and freight is $2,102.49 with the core charge included. Core refund eligibility changes the final net cost.

A comparable quotation should specify the complete assembly, new or remanufactured condition, included regulator and auxiliary sections, warranty, core terms and shipping. Installation and diagnosis are separate unless the offer includes them. Mixing those scopes makes advertised prices misleading.

Buying a used excavator as a complete machine

Whole-machine buyers provide model, working needs and destination, then request machine-specific condition information.

Comparing pump makes is part of evaluating an excavator. If you’re sourcing an entire machine, take a look at our used excavators for sale and contact us for your model, required working needs and destination via our contact page. Ask for machine-specific condition information before agreeing on the purchase scope.
