Our F series single acting triplex mud pumps which include Models of F-500, F-800, F-1000, F-1300 and F-1600 are interchangeable with Emsco pumps. The products keep the features in F series including advanced structure, small size, reliability and easy to maintenance.

Gear Pair It adopts herringbone gear transmission with larger transmission torque and stable performance.

Frame The frame is welded with steel plates. The pinion shaft bearing seat and the upper and bottom seats of crankshaft are made of cast steel and the frame is processed to eliminate stress after welding, therefore, it has good stiffness and strength. The bottom seat of crankshaft adopts slab reinforced structures. There are necessary oil sump and oil pipeline system within the machine frame, which are used for cooling and lubrication.

Crank Shaft  The Crank shaft is made of cast alloy steel. The inner bore of the herringbone gear and the crankshaft are jointed together by interference fit and fastened by bolts and locknuts. Both sides of the crankshaft are equipped with double row spherical roller bearings to the heart so as to ensure the stability in operation and to improve the bearing capability.

Pinion Shaft It is made of forging alloy steel. On the shaft there is herringbone gear whose tooth surfaces are of medium hardness. There is shaft extension at both ends, where belt wheels or chain wheels may be installed.

Crosshead The integral crosshead is casted with nodular cast iron so the crosshead has good resistance to abrasion. Apart from F500 pumps, which adopt guide tube structure, all other crosshead guides are made up of an upper and a bottom guide. Gaskets may be added under the crosshead guide to regulate the concentricity. The extension rod is connected to the crosshead by flange with pin so as to ensure the concentricity of the crosshead and the extension rod. The packing adopts double sealing structure, which realizes good seal performance.

Fluid Cylinder The fluid cylinder is made of forged alloy steel. Our F series pumps adopt straight-through type cylinders, with saw tooth threads at the top side. They are small in size and the volumetric efficiency is very high. The cylinder surface is processed by nickel-phosphor plating in order to increase their resistance to corrosion. The three cylinders of a pump are interchangeable.

Valve Assembly F500 pump adopts API #5 valves, F800 and F1000 pumps adopt API #6 valves, F1300 and F1600 pumps adopt API #7 valves, F2200 pump adopts API #8 valves.The parts of the fluid end of F800 and F1000 are interchangeable. The parts of the fluid end of F1300 and F1600 are interchangeable.

Lubrication System The lubrication system adopts pressure lubrication combining with splash lubrication, or otherwise it may also adopt external motor driven lubrication according to the customer’s requirement.

The spraying system The spraying system is composed of spraying pump, water tank and spraying pipes. The spraying pump is a centrifugal pump. It can be driven by a belt wheel installed on either side of the pinion shaft or by a motor, using water as cooling and lubricating liquid.

Cantilever Hoister System In order to reduce the labour intensity of drilling workers, and for easy field operation, the F1300 and F1600 pumps are equipped with a cantilever hoister, which is used to help removing or replacing the liner or other parts of the fluid end.
