20/914900 Parker JCB Triple Hydraulic Pump 36+16+19cc 275 bar

Product Overview

The 20/902900, 20/912800, 20/914900, 20/915000, 20/914600, 20/916700, and 20/916800 series hydraulic gear pumps are Parker Hannifin’s purpose-built main hydraulic pumps for JCB 3CX / 4CX series backhoe loaders and JCB Loadall telehandlers. Featuring tandem (dual-section) or triple-section gear pump configurations, these units deliver multiple independent hydraulic outputs from a single drive shaft input, making them the core power components of JCB equipment hydraulic systems.

JCB, a globally renowned construction equipment manufacturer founded in 1945, has consistently upheld the spirit of “Jamais content” (never satisfied) in its pursuit of innovation. As an OEM supplier to JCB, Parker manufactures hydraulic pumps with precision construction, durable materials, and factory-level performance parameters.

This product range comprises three main categories:

• Tandem Pump (33 + 29 cm³/rev): Corresponding to 20/902900 and 20/912800, with 33 cc/rev front and 29 cc/rev rear displacements

• Tandem Pump (36 + 26 cm³/rev): Corresponding to 20/912800 (alternate configuration)

• Triple Pump (36 + 16 + 19 cm³/rev): Corresponding to 20/914900, with 36 cc/rev front, 16 cc/rev middle, and 19 cc/rev rear displacements

Key Interchangeability Advantage: Our series of gear pumps are manufactured to strict Parker original design specifications, ensuring 100% direct interchangeability with original units. All mounting interfaces (SAE B 2-hole or 4-hole flange), drive shafts (1″ diameter SAE splined or parallel keyed shaft), and port configurations are identical to the original product. Every pump undergoes 100% factory performance testing under simulated operating conditions (covering rated pressure, peak pressure, and full speed range performance curves), guaranteeing plug-and-play reliability with zero performance deviation.

Key Technical Advantages

1. Multi-Section Integrated Design for Independent Multi-Circuit Output

Two or three independent gear sections are integrated in series within a single cast iron housing, driven by a single input shaft to simultaneously power multiple pump stages. The 20/902900 and 20/912800 are tandem configurations, independently supplying oil to the working attachment (loading/excavation) and steering/auxiliary systems. The 20/914900 is a triple configuration, simultaneously powering three independent hydraulic functions. This design dramatically simplifies hydraulic piping layout on JCB equipment, reducing external connection points and leakage risks.

2. High-Strength Cast Iron Housing for Demanding Conditions

Manufactured with high-strength cast iron housing, offering excellent impact resistance and structural rigidity to withstand high-frequency vibration and heavy shock loads encountered by JCB 3CX/4CX machines in construction sites, quarries, and other harsh environments. Precision construction and durable materials guarantee the maintenance of factory pressure and flow parameters.

3. SAE Standard Interface for Direct OEM Replacement

Manufactured to strict Parker original design standards with mounting flange, drive shaft, and port dimensions and positions identical to original units. The SAE B standard flange and 1″ diameter drive shaft (parallel keyed or 15-tooth SAE splined) precisely match JCB factory drive interfaces – direct installation with no modifications required.

4. High Pressure Capacity for Heavy-Duty Operations

Front and rear pumps both deliver maximum working pressure of 275 bar with maximum input shaft torque of 325 Nm – fully meeting the power demands of JCB 3CX/4CX excavating, loading, steering, and other hydraulic functions. The triple pump configuration is designed for JCB Loadall telehandler multi-function hydraulic systems.

5. Broad Compatibility Coverage

This pump series is compatible with dozens of JCB 3CX, 4CX, 214, 215, 216, and 217 backhoe loader model variants, as well as JCB Loadall telehandlers and 801 series mini excavators. The 20/902900 and 20/912800 share part number interchangeability (Alternative part numbers: 20/902900, 20/912800, 400/E0868).

Expert Maintenance Tips

1. Model Confirmation and Selection

• 20/902900 and 20/912800 are tandem pumps (33+29 or 36+26 cm³/rev) with part number interchangeability. Verify original machine main pump displacement specifications to select the correct model.

• 20/914900 is a triple pump (36+16+19 cm³/rev) specifically designed for JCB Loadall telehandlers.

• 20/914600 is compatible with JCB 801 series mini excavators.

• Always provide equipment serial number to confirm part compatibility.

2. Pre-Installation Checks

• Confirm pump rotation is counter-clockwise (viewed from shaft end), matching JCB original drive direction.

• Check drive shaft type (20/902900/912800: 1″ parallel keyed shaft; 20/914900: 1″ 15-tooth SAE B-B splined shaft) – never use hammer-driven installation.

• Confirm port specifications (front 1 1/16″-12 UNF, rear 7/8″-14 UNF) precisely match hydraulic fittings.

3. First Start-Up & Oil Priming

• Prime the pump housing with clean hydraulic oil before first start-up; ensure suction line is fully filled – never run dry.

• Recommended fluid: JCB OEM-spec anti-wear hydraulic oil.

• Combined 2″ SAE flange inlet – ensure suction line is unobstructed.

4. Filtration & System Flushing

• Thoroughly flush the hydraulic system before installing a new pump to prevent metal debris from a worn pump contaminating the new pump and destroying the entire hydraulic system.

• Maintain fluid cleanliness at ISO 4406 class 18/17/14 or better.

• Regularly monitor fluid cleanliness to prevent contaminants from accelerating gear and bearing wear.

5. Operating Monitoring

• Front and rear pump maximum working pressure must not exceed 275 bar.

• Maximum input shaft torque 325 Nm – ensure prime mover output torque meets this requirement during system design.

• If any of the following failure symptoms occur, immediately shut down and inspect: lack of power on all hydraulic functions, very slow operation (especially with warm oil), loud “whining” pump operation indicating cavitation or seizure, hydraulic oil overheating, or metal filings in oil and filter.

• Completely depressurize the hydraulic system before pump replacement: lower all attachments to the ground and operate all levers with the engine off.
