Centrifugal Pump

Part I: GN Centrifugal Pump

• Long-life mechanical seal
• Thick, strong, concentric casing
• Famous brand bearing
• Open impeller design, lower axial thrust loads, easy for installation and maintenance
• Complete unit with pump head and motors mounted on one skid

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. 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.

Centrifugal Pump for drilling fluids solids control

An oilfield solids control system needs many centrifugal pumps to sit on mud tanks. The pumps are generally used to transfer drilling mud to make it circulate through tank system. According to mud feeding and drilling flow locations we name the centrifugal pump as feeding pump for desander / desilter or mud cleaner, mixing pump for jet mud mixer, trip pump for trip tank and supercharging pump for rig mud pump.

 Part II:Shear Centrifugal Pump

GNJQB series Shear Centrifugal Pump is new type equipment with compact structure. It enables the drilling staff to configure an desired drilling mud specification in a fast way. The shear pump is driven by an electric motor through a belt group, high strength impeller can mix the mud material effectively and transfer it to mud tank, reduce the time of configuration, and provide the high performance of the mud for the oil well drilling.

Shear Pump for Drilling Fluids Solids Control

In the solids control system, shear pump helps reduce the cost of polymers and clays and improve mud property. High cost mud chemicals can be sheared by the shear pump to eliminate the fish eyes and prevent polymer long strings, thus they could smoothly pass the shaker screen and maintain in the mud circulation system. GN shear pump impeller is specially designed to have winder flow pass and smooth vanes which make the pump reach the international efficiency and energy-saving standards. Made of high wear resistant cast iron, the impeller has a longer service life. Packed with a mixing hopper, pipeline and valve, the shear pump could be used as a jet shearing unit in the drilling mud recycling system.

Part III: Vertical Centrifugal Pump

GNYZ Vertical Centrifugal Slurry Pump is the cantilever pump structure of single stage and single suction. It mainly composes of bearing housing, supporting, intermediate pipe connecting the pump hydraulic components. The liquid is discharged out from the drain pipe parts; pump impeller is for semi-shrouded with the agitating vane on the vane extended. The main characteristic of the slurry pump is that shaft parts of underwater pump are rigid enough. The impeller and pump shell have no bearings or shaft seal, which can convey larger medium of solids particles. The depth of the slurry pump below the water is between 800 and 2000mm; the suction pipe can be matched if needed. The shaft runs into the underwater pump without setting up the shaft seal, vertical motor installed on the supporting seat connecting with coupling to drive and pump.

Submersible Slurry Centrigual Pump for Drilling Fluids Solids Control

• Feeding Shale Shaker from Mud Pit for HDD Mud Recycling System
• Feeding Desander Desilter
• Feeding Decanter Centrifuge

GNYZ Submersible slurry pump is also called cellar pump. It is structured of vertical single stage and single suction system overhung centrifugal pump. It is made of abrasion-resistant alloy, it can convey medium with high concentration particle by using centrifugal force. There is no bearing and Gland Seal between impeller and pump body, so the slurry pump is maintenance-free and high temperature resistance.
