The efficiency of a multi-section hydraulic system in construction machinery determines the ability to simultaneously and smoothly control travel, cab rotation, and working arm operation.

The presented FZ Hydraulics triple hydraulic pump is a proven equivalent designed to restore nominal working parameters in Schaeff and Atlas excavators.

The housing construction allows for continuous operation under high pressures, minimizing the risk of equipment downtime in the field.

Technical data and mounting specification:

Triple FZ Hydraulics design: Precisely machined internal pumping components for three sections (with capacities of 7.5 + 7.5 + 5.5 cm³/rev.) ensure stable oil delivery and high volumetric efficiency. This reduces internal leakage even when the hydraulic oil is heavily heated.
Precise drive transmission: Precise machining of the tapered drive output guarantees a direct and backlash-free connection with the driving engine. This contributes to smooth operation of the entire system and reduces vibration under load.
Wide machine compatibility: The component fits power hydraulics systems in Schaeff HR 12 and Atlas 404 mini excavators.
Full compliance with catalog designations: W9A3-7,5-7,5-5,5-R (direction of rotation: right-hand / clockwise).

Choosing an equivalent from FZ Hydraulics ensures trouble-free installation in place of a worn component and a long service life for the excavator's hydraulic system.

This guarantees stable attachment operation and proper equipment performance under all working conditions.
