About GX Pump

GX Pump logo
GX Pump
China

GX Pump has spent two decades building portable PCP compressors, and it shows in the details that matter: patented compression structures, roller bearings at the wrist pin, and a model range that runs from the entry CS1 up to the water-cooled CS4 with its five-hour continuous duty rating. The -I variants build the 110V converter into the body so one unit covers home outlets and car batteries alike. GX also backs its machines with a genuinely useful parts store, offering filters, seals, fans, and rebuild components that keep these compressors serviceable for years.

Specifications come from manufacturer pages and named retailer listings; blanks mean a value wasn't published, not that it's zero. Fill-time figures are derived estimates, not lab measurements. Always follow the manufacturer's fill and duty-cycle guidance.
