Centrifugal pumpsare used widely in drilling fluids system, as feeding pump, transfer pump, trip pump, charging pump, mixing pump, weighting pump. Mechanical seal became a popular type centrifugal pump at present.

What is mechanical seal?

Mechanical seal is a device which to prevent liquid under pressure from leaking out of the pump, or from drawing air into the pump when under vacuum conditions.

Mechanical seal centrifugal pump is a type of Single-stage & single-suction mud pump, Material of pump housing, stuffing box, impeller, bracket mount is Grey iron casting HT250, and pump shaft is made of 42CrMo, Mechanical seal material including :

Rubber material is viton

Skid, spring is made of SS316

Surface of seal is made of tungsten carbide

Centrifugal pump with mechanical seal some are required by GN Solids Control Clients for drilling mud System.As a manufacturer for mechanical seal centrifugal pump we give explanation info. as below.

Centrifugal Pump

A centrifugal pump is a roto dynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits into the downstream piping system. Centrifugal pumps are used for large discharge through smaller heads.

In some situations, packing material is not adequate for sealing a centrifugal pumps shaft. One common alternative method for sealing the shaft is with mechanical seals. Mechanical seals consist of two basic parts, a rotating element attached to the pump shaft and a stationary element attached to the pump casing. Each of these elements has a highly polished sealing surface. The polished faces of the rotating and stationary elements come into contact with each other to form a seal that prevents leakage along the shaft.

The most effective method of preventing the leakage of the drilling  fluids from the centrifugal pump to the external surroundings is using the mechanical seals. The mechanical seals Continue reading »
