FAQ Section

How does the Hydraulic Gear Pump PSVD2-21 achieve ≥95% volumetric efficiency?

Answer: The PSVD2-21 hydraulic gear pump utilizes precision-ground internal meshing gears and a thermally stabilized assembly process in a dust-free environment to minimize internal clearances. Combined with automated machining for micron-level accuracy and strict post-assembly testing (including pressure decay analysis), leakage is reduced by over 30% compared to standard pumps, ensuring stable fluid transfer efficiency even under 250-bar continuous operation.

How is the Hydraulic Gear Pump PSVD2-21 tested for casting defects?

Answer: Every casting undergoes X-ray scanning (ASTM E505 standards) and destructive cross-section analysis. Pores >0.3mm or cracks are rejected. Post-machining, components are dye-penetrant tested to ensure structural integrity before assembly.

Can the Hydraulic Gear Pump PSVD2-21 be customized for non-HITACHI equipment?

Answer: Yes. Provide flange dimensions, port configurations, and flow/pressure requirements. Our engineers will redesign mounting interfaces and validate compatibility via 3D simulation, with prototype delivery in 20-30 days.

How to troubleshoot leakage in the Hydraulic Gear Pump PSVD2-21?

Answer: Step 1: Check external seals (shaft, ports) for wear or debris. Step 2: Monitor case drain flow—if >10% of rated flow, internal wear may require gear replacement. Contact support for pressure decay test guidelines or onsite service.
