High Reliability PV Pump with Reinforced Shaft and Dual Hydrostatic Bearings
HPV pumps incorporate advanced high-pressure port sealing to prevent external leakage.
Customizable through-shaft options enable integration with secondary drive accessories.
Precision lapping of mating surfaces ensures minimal internal leakage under load.
Integrated control valve blocks simplify system design and reduce external plumbing.
High-grade steel bearings support extended operating cycles without fatigue.
PV20 Fast Delivery Hydraulic Piston Pump
our advantage
Product Description
Through computational flow analysis, the internal porting of the HPV pump is optimized to reduce pressure drop and turbulence. The result is smoother flow delivery, enhanced volumetric efficiency, and reduced heat generation.
Product Features
The reinforced swash bearing design maintains alignment during dynamic pressure changes.
Innovative oil recirculation design prevents localized overheating in high-duty cycles.
Balanced cylinder block construction reduces oscillation and mechanical resonance.
Anti-cavitation flow paths maintain continuous suction pressure under low inlet conditions.
Wide range of displacement settings supports diverse application requirements.
