Product details

Hydraulic plunger pump A2FO45/61L-PZB05-S

Product Overview

A2FO45/61L-PZB05-S is a Rexroth bent-axis fixed displacement Hydraulic piston pump, also named hydraulic plunger pump. It is a high-pressure hydraulic pump, designed for robust open-loop hydraulic system and heavy-duty industrial & mobile Machine. This pump adopts classic bent-axis piston construction, delivering constant flow proportional to the rotating speed, acting as the core power source for high-pressure hydraulic circuits of construction Machine.

This hydraulic plunger pump has a heavy cast iron housing with outstanding mechanical strength. Precision pistons and valve plate assembly reduce internal leakage, maintaining high volumetric efficiency under continuous high pressure. It converts rotary mechanical energy into pressurized hydraulic oil to drive cylinders and hydraulic actuators inside the hydraulic system.

Working Principle

When the Machine operates, the drive shaft spins the cylinder block of this hydraulic plunger pump. Thanks to the 40° bent-axis design, the pistons perform reciprocating linear motion inside cylinder bores, finishing oil suction and discharge cycles. As a fixed displacement hydraulic pump, it produces stable constant flow at a fixed rotating speed.

Pressurized hydraulic fluid is transmitted to the hydraulic system to actuate the working components of the Machine. Reinforced heavy-duty bearings endure high pressure and strong vibration during continuous running. The precision matching of piston and valve plate ensures stable flow output even under frequent pressure spikes, protecting the whole hydraulic system from premature damage.

Core Advantages

1. As Rexroth bent-axis fixed Hydraulic piston pump, this hydraulic plunger pump features ultra-high pressure resistance, perfectly suited for heavy-duty open-loop hydraulic system of mobile Machine.

2. 40° bent-angle structure delivers excellent power density, compact overall size for equipment with limited installation space.

3. Precision piston and sealing assembly greatly lower internal leakage and volumetric loss, reducing heat generation within the hydraulic system.

4. Reinforced drive shaft and bearing assembly, strong anti-vibration & impact resistance, extending the service cycle of your Machine.

5. Standard interchange dimensions, suitable for OEM assembly and spare part replacement of the hydraulic system.

Application Range

A2FO45/61L-PZB05-S hydraulic plunger pump, the fixed Hydraulic piston pump, is widely applied as the core hydraulic pump in the hydraulic system of concrete mixers, cranes, road rollers, drilling rigs and other heavy engineering Machine. It is popular among hydraulic equipment manufacturers, repair workshops and global spare parts distributors.
