Product Detail
The rotary oil pump: 1.Efficiency is higher,up to 80%. 2.Transfer medium that is from low viscosity to high viscosity.

Unloading pump

Unloading pump can transfer medium that is from low viscosity to high viscosity,or with larger particles of impurities,or some corrosive medium and the medium that require low shear rate .It can be widely used in environmental protection,chemicals,petroleum, mining,construction,shipping,

ceramics,and food processing and agriculture industries.Such as:conveying sewage,waste oil,mud water,mining waste,waste fuel oil,lime white,washing liquid,emulsion and so on.Flow range can cover 10m3/h-200m3/h.

Motor unloading pump

The device adopts the unloading equipment composed of GMTB cam rotor pump and YS explosion-proof speed adjustable motor.

Diesel engine unloading pump

The matching device is equipped with a diesel power pack.The configuration is complete,and the application range is wide.It combines unloading pump,power pack,hydraulic lines and support as a unit,which facilitates crane or forklift to move.

Structural characteristics

The pump adopts the meshing rotation of two elliptical arc cam rotors,and depends on the valley of cam to squeeze fluid from one side to another side along the pump shell.The cam rotor,driven by gear,rotates synchronously and makes the liquid move.The flow increases when the speed increases,and the outlet pressure increases when the speed increases,and the outlet pressure increases when back-pressure increases.

Performance characteristics

1,The flow has liner relationship with speed,and different working pressure need different input power

2,The medium whose particles are of large diameter can pass well,and the largest diameter of particles can be up to about 40 mm.

3,Because the surface of salient pole rotor is elastic,so the seal is particularly good and improve the capacity of self-suction.

4,Efficiency is higher,up to 80%.
