A7V80LV1LZF00 Rexroth A7V Hydraulic Plunger Pump 350bar

Product Overview

The A7V80LV1LZF00, A7V107LR/60R-PPB01 and A7V250LRD/63R-VPB01 are Bosch Rexroth A7V/A7VO series bent-axis axial piston variable displacement pumps designed for open-circuit high-pressure applications. Flow is proportional to drive speed and displacement and can be steplessly adjusted. Manufactured to original technical standards with full dimensional, interface and control interchangeability, each unit undergoes 100% simulated operating-condition testing for volumetric efficiency, pressure stability and service life, delivering reliable drop-in replacement performance for mobile and industrial hydraulic systems.

Key Technical Advantages

1. Precision bent-axis and spherical port-plate design: Enhanced rotary group and optimized porting reduce noise by approximately 5 dB(A) while improving volumetric efficiency and contamination resistance.
2. High volumetric efficiency with constant-power / pressure-cut-off control: LV/LR/LRD regulators maintain power or limit pressure according to load, minimizing relief losses and heat generation.
3. Robust long-life bearing system: Heavy-duty roller bearings support intermittent high-pressure operation; long-life bearing versions available for continuous duty.
4. Full interchangeability and 100% duty-cycle testing: Mounting flanges, ports, shaft ends and control characteristics match original Rexroth units exactly. Every pump is tested under simulated pressure, flow, leakage and noise conditions prior to shipment for true plug-and-play reliability.

Application Areas

Construction machinery (excavators, loaders, cranes), industrial hydraulic power units, marine deck equipment, metallurgical machinery, injection-molding machines, mining equipment and any open-circuit system requiring high pressure and variable flow.

Expert Maintenance Tips

Ensure absolute inlet pressure at the suction port is at least 0.8 bar (adjust according to speed and displacement) to prevent cavitation. Fully bleed the system and verify correct rotation direction before first start-up. Use hydraulic fluid meeting ISO 4406 cleanliness class 20/18/15 with recommended operating viscosity 16–36 mm²/s. Monitor case-drain temperature (max. 90 °C) and bearing condition regularly. When replacing, always confirm the complete type code (control, shaft, seals and series index) so that control springs and pressure-cut-off settings match the original machine. For long-term storage, drain the fluid and apply corrosion-protective oil.
