Emsco F-800

Mud Pumps

The Emsco F-800 is a triplex single-acting mud pump long regarded as a workhorse for drilling and workover service, built with high-strength materials and precision engineering to stand up to harsh drilling environments while running efficiently. Factory data lists 800 HP rated input power, 5075 PSI max working pressure, 627 GPM max flow, a 9 in stroke length and 150 SPM rated speed. The fluid end accepts liners from 4 in (101.6 mm) up to 6.75 in (171.45 mm): with a 6.75 in (171.45 mm) liner it delivers 627 GPM at rated SPM against max 1965 PSI, while a 4 in (101.6 mm) liner delivers 220 GPM at rated SPM against the full 5075 PSI. We supply the complete fluid-end wear group for this model across Canada, the United States and international oil and gas markets.

FAQ

What fluid-end parts are available for the Emsco F-800?

We supply Liner （缸套）, Piston （活塞）, Valve （阀）, Valve Seat （阀座）, Valve Spring （阀簧）, Packing （盘根）, Fluid End Module （液力端模块） assemblies and Fluid End Repair Kit （液力端维修包） sets for the F-800.

What are the factory ratings of the Emsco F-800?

Factory spec data lists 800 HP rated input power, 5075 PSI max working pressure, 627 GPM max flow, a 9 in stroke length and 150 SPM rated speed.

What output does the F-800 deliver with different liners?

Per factory data at rated SPM: a 6.75 in (171.45 mm) liner gives 627 GPM against max 1965 PSI, a 5 in (127 mm) liner gives 344 GPM against max 3585 PSI, and a 4 in (101.6 mm) liner gives 220 GPM against the full 5075 PSI.

How do I choose the right liner for my F-800?

Match the liner to your target pressure and flow: larger liners favor volume, smaller liners favor pressure. Share your program requirements and we will supply the correct Liner （缸套） and Piston （活塞） combination.
