Centrifugal pump is the ideal solids control equipment to provide impetus for desander, desilter and jet mud mixer. It can also be used as charge pump auxiliary perfusion for mud pump and trip pump for drilling well head. It is also called sand pump. Besides, it takes full consideration in the design of its parameters whether the equipment may operate in the best conditions. Its advantages are the strong versatility and interchangeability of its parts, less leakage in shaft seals, stable performance, long service life and ease of maintenance.
 

How to install a drilling pump in solids control system?

The pump should be located near the liquid source so that the suction line can be short and reduce losses. The foundation should be sufficiently rigid and substantial to absorb any vibration and support the base plate at all points. The base plate should be installed in a level position.

Connection of the Suction Pipes

1. The suction line should be equal to or larger than the pump suction.

2. The capacity of a centrifugal pump should never be adjusted by throttling the suction line, but a positive shut-off valve of a type to cause minimal turbulence should be installed in the suction line to permit the closing of the line for removal of the pump for inspection and maintenance.

3. The suction line should be designed to eliminate any air pockets. The pipes should gradually slope downwards to the supply source to eliminate air pockets. Please use a vacuum pump or foot valve for priming if you operate the pump under the condition of suction lift.

4. The suction line should have a straight section into the pump of a length equivalent to at least two times its diameter.

5. For temporary hook-up when flexible hose is used, a non-collapsing hose is essential since the suction line pressure is often below atmospheric pressure. A collapsed suction line will result in below average or complete loss of flow.
