First, Use and scope of application
ZSB series centrifugal sand pump is mainly used to the oil field drilling machine supporting the cycle of solid control system, its role is to desander, desilter, mixer, etc. to provide a certain displacement and pressure drilling fluid to ensure that these equipment efficient work.
JSB10 × 8 × 14 centrifugal sand pump is mainly adapted to support more than 3000m drilling rig, drilling fluid viscosity, the proportion of relatively large drilling engineering use; JSB8 × 6 × 14 centrifugal sand pump main support more than 3000m rig; JSB8 × 6 × 11 centrifugal sand pump main support 3000m below the rig, but also as a filling pump to the three-cylinder mud pump for the slurry; JSB6 × 5 × 11 centrifugal sand pump is generally used for car rigs or small rigs supporting; JSB4 × 3 centrifugal sand pump and metering tank supporting, usually called metering pump or feed pump; JSB3 × 2 centrifugal sand pump is generally used as a clean water pump.

Second, The Structural Characteristics
Centrifugal sand pump mainly by the pump shell, impeller, pump shaft, wear plate, sealing device, bearing, coupling, motor, base and other components. The series of centrifugal sand pump is characterized as
1. Open impeller, suitable for conveying high viscosity drilling fluid;
2. Combination of sealed, long service life;
3. All models of centrifugal pump bearing, shaft and other parts common, easy maintenance, cost savings;
4. The main parts are wear-resistant ductile iron, resin sand precision casting, long life, good looks.
