GN Shearing pump saves the cost of mixing polymers and clays while improving mud properties. Shearing the polymers eliminates fish eyes and prevents polymer chaining (long strings), which cannot pass through the shaker screens. The Shear pump is available as a belt-driven or diesel-driven package including a mud hopper, mud gun, and transfer line orifice plate. A complete system with skid, tanks, and piping are also available.

Feartures of GN Shear Pump

The GNJQB6545 shear pump adopts a set of compound seal for no leakage at stuffing box. Inside pump is a 300series stainless steel turbine containing 44 nozzles, four scoops and shear plate. Fifty(50)% of the fluid is sheared twice each time through the pump. This turbine shear pump is mounted on a special base with belts and sheaves to drive pump, OSHA type belt guard and a 75HP(55KW)1800RPM EXPLON PEROOF U/L approved electric motor, 460 volt, 3 phase 60 cycle. Included is a special hopper(ZHP150) with nozzle sized for this
application and one mud kit as a package in order to build a complete shear and hydration system. The pump is designed to give longer service life through the improved.

Principles of the installation for shear pump

There are many principles of proper pump installation and application as well as special considerations for the pump design which, if followed, will further enhance the performance of your GNJQB turbine shear pump.

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

The capacity of a centrifugal pump should never be adjusted by throttling the suction line, but a positive shutoff 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.

The mud mixing system normally use shear pump to connect with hopper for mixing.
