China centrifugal pump

Actually, in China oil industry we usaully call centrifugal pump as “Sand pump”. Since the pumps are mainly used to pump drilling mud for Desander, Desilter, or mud cleaner.

Pumps transfer mud between mud tank and equipment. Finally, drilling fluid is transfered from one compartment to another; one tank to another.

The centrifugal pump can be divided into vertical type and horizontal type. Now we just take horizontal type compared with Mission pump.

The pump in China including oil seal type and mechanical seal type. For the mechanical seal pump, it is widely appreciated by oil&gas industy users, since it’s more stronger, and more durable.

NOV Mission pump features

Thicker, Stronger, Concentric casing. All of Mission pumps featur a concentric casing that is an average of 37% thicker than conventional pump casings, and up to 50% thicker for the larger, mud pumping models. They are pressure rated at 1.5 times the flange rating and are designed with a 1/8″ erosion allowance.
