The XPi series hydraulic pump is a high-pressure fixed displacement bent-axis piston pump designed specifically for truck hydraulic applications.
Their compact design allows a direct flange-mounting on the PTO. All models are of 7 piston design to ensure optimal flow regularity, and can withstand continuous working pressures up to 380 bar and 420 bar peak.
These bidirectional pumps require no user intervention to change the direction of rotation (simple switching of the inlet fitting). Available in displacements from 12 to 130 cc/rev, Green Hydraulic offers the most extensive range of fixed displacement truck pumps on the market. Suitable inlet fitting supplied with the pump.
Typical applications include:
truck equipment (examples: truck cranes, forestry cranes, hook lift, skip loader, stabilization cylinders),
snow and ice equipment (examples: spreaders, snow blades, turbines),
fire trucks,
military.
Unlike traditional hydraulic pumps that require complex installation adjustments, XPi pumps simplify mounting through their bidirectional rotation capability, making them easier to integrate into PTO-driven truck hydraulic systems.
The XPi series hydraulic pump features a fixed displacement bent-axis piston design, developed for high-pressure mobile hydraulic applications.
Its optimized structure combines compact dimensions, high efficiency and reliable operation, making it suitable for truck-mounted hydraulic systems where space and performance are critical.
The XPi series uses a 7-piston bent-axis structure.
Compared with traditional gear pumps, piston pumps provide higher pressure capability and better efficiency, especially in demanding hydraulic applications.
The fixed displacement design means:
Hydraulic flow is proportional to pump speed
Simple hydraulic control
Reliable performance
Easy system integration
Unlike conventional fixed-direction hydraulic pumps, the XPi series can adapt to both clockwise and counter-clockwise rotation.
The rotation direction is adjusted by selecting the appropriate inlet port configuration, allowing the pump to match different PTO output directions without changing the pump model.
This feature makes the XPi series easier to integrate into truck-mounted hydraulic systems, especially where installation space and PTO configuration vary.
Truck chassis often have limited installation space.
The XPi pump is designed with a compact structure, allowing installation:
Directly on PTO systems
In narrow chassis spaces
On mobile hydraulic equipment
This makes XPi suitable for applications where traditional pumps cannot be installed easily.

The XPi series is available in multiple displacement options from 12 to 130 cc/rev, allowing customers to select the suitable pump according to different truck hydraulic applications.
The main factors to consider are: Pump displacement determines hydraulic flow.
The basic relationship is:
Flow Rate = Displacement × Speed × Efficiency
A larger displacement pump provides higher flow at the same rotation speed.
When selecting an XPi pump, consider:
Required cylinder speed
Hydraulic system flow demand
PTO rotation speed
For example:
Smaller models such as XPi 12, XPi 18 and XPi 25 are suitable for lower flow requirements.
Medium models such as XPi 41, XPi 50 and XPi 63 are commonly used in truck hydraulic applications.
Larger models such as XPi 80, XPi 108 and XPi 130 are suitable for systems requiring higher hydraulic output

Proper installation is important to ensure the performance and service life of the XPi hydraulic pump. Since XPi pumps are mainly used in PTO-driven truck hydraulic systems, the installation should consider PTO compatibility, rotation direction, hydraulic connections, and oil supply conditions.
Before installation, confirm that the PTO speed, mounting connection, and rotation direction match the pump requirements. The XPi series supports both clockwise and counter-clockwise rotation, providing flexibility for different truck configurations.
The hydraulic system should use suitable hydraulic oil, proper filtration, and correctly sized suction lines to ensure reliable pump operation. Poor installation conditions may cause noise, cavitation, reduced efficiency, or premature wear.
Before operation, check all connections, confirm the pump rotation, and verify system pressure and temperature during commissioning.
Although XPi hydraulic pumps are designed for reliable operation in demanding truck hydraulic systems, performance issues may still occur due to incorrect installation, hydraulic system conditions, or normal wear over time.
Common issues include low hydraulic pressure, insufficient hydraulic output, abnormal noise, reduced performance, and oil leakage. These problems are often related to factors such as incorrect rotation configuration, air entering the suction line, insufficient oil supply, restricted hydraulic connections, contaminated oil, or internal pump wear.
When troubleshooting an XPi pump, it is important to check the complete hydraulic system rather than the pump alone. Confirm the pump installation, PTO rotation direction, hydraulic oil level, suction conditions, filtration system, and operating pressure before replacing components.
Regular inspection, proper hydraulic oil maintenance, and correct installation can help maintain XPi pump performance, reduce downtime, and extend service life.
When replacing an XPi hydraulic pump, choosing the correct replacement requires more than matching only the pump displacement. The pump should be selected according to the complete hydraulic system requirements, including application, PTO configuration, rotation direction, mounting connection, working pressure, and flow requirements.
