Caterpillar is the benchmark. When a contractor runs CAT equipment, they're not compromising on anything — and they shouldn't have to when it comes to replacement parts either.
The problem is simple: a new CAT SBS140 or SBS120 pump through an authorised dealer costs ₹2.5-4 lakh and can take 6-8 weeks to arrive. For a machine sitting on a live construction or mining site, that's unacceptable.
PumpGrid's refurbished CAT pumps are pulled from machines with documented histories, fully disassembled, measured to OEM tolerances, rebuilt with new seals and bearings, and bench-tested at rated pressure. The test report goes with every pump. Performance is identical to new — at 40-60% of the cost, dispatched in days.
The CAT Difference — And Why It Still Applies to Refurbished
CAT pumps (the SBS series and E-series) are engineered to tighter tolerances than most OEM competitors. This actually makes a properly refurbished CAT pump more reliable than a new compatible aftermarket unit — because you're working with a CAT-engineered body, not a copy. We preserve that advantage in our refurbishment process.

Our Caterpillar Quality Guarantee
Measured to CAT OEM Tolerances
CAT pump internals — pistons, barrel, valve plate — are measured with precision instruments after disassembly. Any component outside CAT's specified clearance range is replaced. We don't guess; we measure.
SBS Series Test Protocol
CAT SBS pumps have a specific test sequence — pressure, flow, case drain flow, and noise. Every PumpGrid-supplied CAT pump is run through this complete sequence, with results documented in your test report.
3-Month Warranty — Documented
Minimum 3-month warranty on all refurbished CAT pumps. If the pump fails due to a refurbishment defect, we arrange a replacement — not a repair cycle. Your written warranty terms are confirmed at the quote stage.
Tested at CAT Rated Pressure
CAT excavator pumps operate at up to 340 bar. We test at this pressure — not at a reduced test pressure — to confirm the pump will perform under actual site conditions.
