Canpump CT 3510 GB: 3200 psi @ 9.8 US gpm, 1-in Shaft Pump with Gearbox & Unloader Valve

At the top-end of our premium 22 mm plunger pumps for direct-drive gas engines sits the CT 3510 GB (formerly DBF-2221G4). Its gearbox effectively reduces the RPMs coming out of the engine, significantly extending the pump's life.

This replacement pump kit offers near-universal compatibility for standard 1-inch shaft direct-drive gas engines from brands such as Honda, Annovi Reverberi, RIDGID, Blackmax, Generac, Husky, Excell, Troy-Bilt, Sears, Briggs & Stratton, and Campbell Hausfeld.

Constructed with forged brass and anodized aluminum, this pump features cooling fins and durable 22 mm ceramic-coated solid stainless steel plungers. The German-made packing seals ensure quality and reliability.

The pump also includes a detachable and pressure-adjustable internal bypass unloader valve with a detergent injector and built-in water filter. Its triplex plunger pump mechanism and sight glass for oil inspection add to its functionality.

Furthermore, the pump comes with a detergent tube with a strainer, a set of extra O-rings, and an operating manual with a spare parts list. Customers also benefit from 7x5 toll-free phone, email, and live chat support from Canada.

The pump's specifications include a pressure of 3200 psi (217 bar), a flow rate of 9.8 US gpm (37.3 L/min), and a power of 22 hp. With a gearbox reduction, the RPM ranges from 3400 to 1560 rpm. The inlet is ¾″ F (including a ¾″ Male to 1" Male adapter), while the outlet is ⅜″ F.
