Product details

Hydraulic plunger pump A2FO23/61L‑PZB06

Product Overview

A2FO23/61L‑PZB06 is a Rexroth bent‑axis fixed‑displacement Hydraulic piston pump, also named hydraulic plunger pump. It is a high‑pressure hydraulic pump built for heavy‑duty open‑loop hydraulic system and mobile & industrial Machine. Featuring classic 40° bent‑axis axial‑piston structure, this pump delivers constant flow proportional to rotational speed, acting as the core power source for high‑pressure hydraulic circuits of engineering Machine.

This hydraulic plunger pump adopts heavy‑duty cast‑iron housing with high mechanical strength. Precision one‑piece tapered pistons with piston rings minimize internal leakage, maintaining high volumetric efficiency under continuous high‑pressure operation. It converts rotary mechanical power into pressurized hydraulic oil to drive hydraulic cylinders and actuators inside the hydraulic system.

Working Principle

When the Machine runs, the drive shaft rotates the cylinder block of this hydraulic plunger pump. The 40° bent‑axis geometry makes pistons reciprocate inside cylinder bores to complete suction and discharge cycles. As a fixed‑displacement hydraulic pump, it outputs stable constant flow at fixed rotating speed[(Rexroth Pa...)].

Pressurized hydraulic fluid flows into the hydraulic system to actuate working components of the Machine. Reinforced heavy‑duty bearings resist high pressure and vibration under continuous operation. Precision‑matched piston‑valve‑plate assembly keeps steady 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 offers outstanding high‑pressure resistance, ideal for heavy‑duty open‑loop hydraulic system of mobile Machine.

2. 40° bent‑axis structure achieves excellent power density with compact size, suitable for equipment with limited installation space.

3. One‑piece tapered pistons with piston rings reduce internal leakage and volumetric loss, lowering heat generation inside the hydraulic system.

4. Reinforced shaft‑bearing assembly delivers strong anti‑vibration and impact resistance, extending service life of the Machine.

5. Standard interchangeable dimensions, fit for OEM assembly and spare‑part replacement of the hydraulic system.

Application Range

A2FO23/61L‑PZB06 hydraulic plunger pump, the fixed Hydraulic piston pump, is widely used as core hydraulic pump in the hydraulic system of concrete mixers, truck cranes, road rollers, drilling rigs, agricultural machinery and other heavy‑duty engineering Machine. It is well‑received by hydraulic equipment manufacturers, repair workshops and global spare‑parts distributors.
