General introduction

Reciprocating plunger pump is a kind of positive displacement pump, that converts the mechanical energy into hydraulic energy by sucking the liquid into a cylinder. In this pump, a plunge is reciprocating, which uses thrust on the fluid and increases its hydraulic energy. It is often used where a small quantity of fluid handled and where delivery pressure is quite large.

Normally there are three-plunger/piston pump and five-plunger/piston pump.

General introduction

Rotary lobe pump is a kind of positive displacement pump, the two or three rotary lobes installed on shafts are driven through timing gears, during operation the sealed chambers are formed between casing and rotors, fluid is suctioned from pump inlet and discharged to pump outlet almost without any shear force or pulsation, it is especially applicable for pumping fluids with certain sludges or suspensions, also big capacity compared to progressive cavity pump.

Sanitary lobe pump with stainless steel wetted parts is applicable for food industry.

General introduction

The slip-fit vanes of pump are placed in the slotted rotor, and the rotor is eccentrically installed in the pump casing. When the rotor is rotated by driver, the sliding vanes slide out of the rotor and close to the internal surface of the pump casing. The cavity chamber formed by the rotor, sliding vanes and pump casing changes periodically with the rotation of the rotor. When the cavity chamber is enlarged, the medium is suctioned and discharged when the cavity becomes smaller. The transmission process of the medium is completed again and again.
