The Caterpillar SBS (System, Basic, Swing) pump series is one of the most robust excavator pump designs in the industry — but it's also one of the most expensive to replace through official channels. A new SBS140 through a CAT dealer can cost upwards of ₹2 lakh with a multi-week wait. PumpGrid's refurbished SBS series pumps deliver the same performance, documented in a written test report, at a fraction of the price and time.

What Makes the CAT SBS Pump Different
Integrated Design
The CAT SBS pump integrates the main hydraulic pump, pilot pump, and in some models the swing motor drive in a single compact assembly — reducing leak points and simplifying installation compared to separate-component designs.
Tighter OEM Tolerances
Caterpillar machines are specified to tighter internal clearances than many competitor brands. This is why a properly refurbished SBS pump — where these clearances are restored — can outperform a generic aftermarket replacement that was never built to CAT's original specification.
Why CAT Operators Choose PumpGrid
Site Downtime is Your Cost, Not the Dealer's
A CAT 330D off-site on a ₹50L/month project costs ₹1.5-2L per day in idle cost and penalties. Waiting 6 weeks for a dealer pump versus 3 days from PumpGrid is a ₹9-12L difference in downtime loss alone — far more than any pump cost saving.
Premium Machine, Not Premium Part Price
Running a CAT machine doesn't mean you have to pay CAT dealer prices for every replacement part. A refurbished SBS pump with documented test results is not a compromise — it's a well-informed procurement decision.
Export-Ready for Gulf Markets
CAT is the dominant excavator brand on Saudi Arabian and UAE infrastructure and oil-sector sites. We regularly export refurbished CAT SBS pumps to Riyadh, Jeddah, Dammam, and Dubai with full export documentation.
Documentation for Large Contracts
Working on a government tender or a large private contract that requires equipment documentation? Our written test report — with actual SBS pump pressure readings — is the documentation your project manager needs.
