Komatsu's HPV (Hydraulic Pump Variable) series is the backbone of India's excavator hydraulic systems. The HPV95 in the PC210, HPV145 in the PC350, and HPV160 in the PC400 are axial piston variable-displacement pumps — sophisticated machines that wear predictably and refurbish exceptionally well when done correctly.

Understanding the Komatsu HPV Series
What HPV Stands For
HPV = Hydraulic Pump Variable. The variable displacement mechanism adjusts output based on system demand — reducing heat generation and improving fuel efficiency compared to fixed displacement pumps. This is why Komatsu excavators run cooler and more efficiently than older designs.
What Wears Out and Why
The primary wear points in the HPV series are the piston slipper pads (which ride on the swashplate), the cylinder barrel kidney ports, and the valve plate. Contaminated hydraulic oil accelerates all three. In a proper refurbishment, these are measured, assessed, and replaced to OEM specification.
What Our Refurbishment Covers
Full disassembly. Piston and slipper assembly inspection — replacement if slipper wear exceeds 0.3mm. Barrel flatness check against valve plate. Shaft seal and all O-rings replaced as standard. Reassembly to OEM torque specs. Bench pressure test at 350 bar with flow measurement. Written report issued.
Why Contractors Choose Refurbished Komatsu Pumps
Dealer Lead Time: 4-8 Weeks. Ours: 2-3 Days
Official Komatsu dealer channels for HPV145 and HPV160 often quote 4-8 week lead times, especially for less common models. PumpGrid dispatches in 2-3 working days — your excavator is back on site before the dealer even confirms stock.
₹70,000-₹1.5 Lakh Saved Per Unit
A refurbished Komatsu HPV pump from PumpGrid typically saves ₹70,000 to ₹1.5 lakh versus new OEM pricing, depending on model. For contractors running 5+ Komatsu excavators, the fleet savings are significant.
The Test Report You Can Show Your Client
Large contractors on government or private projects need documentation. Our written test report — with actual pressure and flow readings — is the paperwork that backs the quality claim and protects your project timeline.
Warranty That Means Something
3-month minimum warranty, confirmed in writing at the quote stage. If the pump fails due to a refurbishment defect within warranty, we replace it — not repair it. Your downtime window stays minimal.
Is Your Komatsu Excavator Showing These Signs?
If 2 or more of the above apply, your HPV pump likely needs refurbishment or replacement. WhatsApp us the symptoms and machine hours — we'll advise the most cost-effective option.
