Designed and manufactured by HNA Plant, F-1300 and F-1600 mud pumps can meet the requirements of the same manufacturing technique and quality level as those of F series mud pumps .They feature advanced structural design, reliable use, easy maintenance and compact occupied area. To reduce drilling workers' labour intensity and make the operation easy on site, liners are designed to be fitted into the frame from the frame top. A mini hoist

with 500Kg lifting capacity is mounted on the frame for disassembling and changing liners.

Suction inlets of F-1300 and F-1600 mud pumps are fitted with 12"flanges, F-1300 and F-1600 mud pumps are fitted with API#7 valve pots. The suction valve and the discharge valve are interchangeable. Cylinders are made of forged alloy steel and nickel plated to improve their corrosion resistance. Three cylinders of each pump are interchangeable. Valve-over-valve (through type cylinder) design reduces the cyliner volume and promote the volumetric efficiency.

Notes: Cylinders, liners, pistons, valves and seats, valve springs, seal rings, valve covers and cylinder covers at the fluid end of F-1300 and F-1600 mud pumps are all interchangeable.
