The Gardner Denver FD-FXX J and K is a twin-cylinder mud pump rated by factory data at a maximum working pressure of 1136 PSI, 52 HP rated input power, an 8 in stroke and a rated speed of 330 SPM. Liner sizes step from 5.5 in (139.7 mm) rated to 338 PSI, through 5 in (127 mm) at 409 PSI, 4 in (101.6 mm) at 640 PSI and 3.5 in (88.9 mm) at 836 PSI, down to 3 in (76.2 mm) rated to the full 1136 PSI. The pump combines a cast iron power end housing with wear-focused fluid-end components such as forged alloy steel piston rods and high-chromium bimetallic liners, built to keep oilfield and general service units running. Staying with correct, well-matched fluid-end parts protects that uptime. We supply these parts to operators in Canada, the United States and international oil and gas markets.
