PRODUCT DESCRIPTION

Variable Displacement Hydraulic Piston Pump A4PVFO Series – High Efficiency Open Circuit Pump

The A4PVFO series hydraulic piston pump is a variable-displacement, high-pressure hydraulic unit built for continuous heavy-load operation. It adopts reinforced friction pairs and optimized flow distribution design to resist abrasion and impact loads. Advanced sealing assembly effectively reduces internal leakage and maintains steady flow output under fluctuating working pressure. Compact body structure supports flexible layout on construction machinery. Wear components can be independently replaced to lower maintenance costs. This reliable pump stabilizes system performance, reduces equipment downtime, and suits demanding open-circuit hydraulic systems for engineering vehicles and mobile machinery.

A4PVFO Series Description

Heavy-duty variable displacement piston pump for mobile hydraulic systems. Constructed with high-strength cylinder block, wear-resistant valve plate and premium sealing kits. Direct interchangeable installation saves assembly time. Delivers precise adjustable flow and stable pressure output under harsh working conditions. Strict pressure cycling testing ensures dependable long-term operation.
