While JCB dominates India's backhoe loader market by sheer volume, Komatsu's WB series holds a steady presence — particularly with contractors who already run Komatsu excavators and prefer a single-brand fleet for parts commonality and operator familiarity. The WB93 and WB93R are common on urban and utility sites in Delhi, Noida and Gurugram, while the larger WB97S and WB97R handle infrastructure and road work in Pune, Ahmedabad and Hyderabad.

Understanding the Komatsu WB Hydraulic Circuit
One Pump, Two Jobs
Unlike an excavator where the main pump serves boom, arm and bucket alone, a backhoe loader's pump powers both ends of the machine — front loader bucket and rear backhoe arm — plus steering and stabiliser legs, often on a single circuit. This makes the pump a genuine multi-tasker, and its wear pattern reflects that combined duty cycle.
What Wears Out First
On a WB-series pump, the most common wear points are the piston/slipper assembly (from continuous load-sensing operation) and the control valve, which regulates flow between simultaneous loader and backhoe demands. Contaminated oil accelerates wear on both.
What Our Refurbishment Covers
Full disassembly and inspection against Komatsu tolerance. Piston, slipper and barrel wear measured. Control valve function tested. Shaft seal and all O-rings replaced as standard. Bench pressure test with flow measurement. Written report issued before dispatch.
Why Contractors Choose Refurbished Komatsu WB Pumps
Faster Than Waiting on a Less Common Model
Because Komatsu backhoe loaders are less numerous in India than JCB, dealer stock of the WB pump is thinner and lead times can stretch to weeks. PumpGrid keeps refurbished units ready to dispatch in 2-3 days.
₹50,000-₹90,000 Saved Per Unit
A refurbished WB-series pump typically saves 40-60% versus new OEM pricing — a meaningful saving on a component that isn't cheap to import.
Documentation for Municipal & Utility Contracts
Contractors on municipal and utility projects in Delhi NCR and Tier-1 cities need maintenance records. Our written test report provides that paperwork.
Warranty Confirmed at Quote Stage
3-month minimum warranty, with replacement rather than repair if a refurbishment defect appears within that period.
Is Your Komatsu Backhoe Loader Showing These Signs?
If 2 or more of the above apply, the pump likely needs refurbishment. WhatsApp us the symptoms and machine hours for an assessment.
