Rotary lobe 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.

Key Features

1.Due to symmetrical structure, shaft rotation direction is reversible

2.Easy installation and maintenance (Maintenance in Place = MIP)

3.Good self-priming ability compared to centrifugal pump

4. Max.50 mm diameter particle is allowed for pumped liquid

5. Low shearing force to pumped liquid

6.Various installation modes



Performance Range

-Capacity: 5 – 1428 m3/h

-Pressure: Max.11 bar

-Speed: 150-500 rpm

-Viscosity: up to 100000 cp

-Temperature: up to 113 ℃

Peristaltic hose pump

General introduction

The peristaltic hose pump is a kind of positive displacement pump with simple working principle, the pumping purpose is achieved by alternately compressing and relaxing a machined hose between the pump housing and the compressing shoes. The fluid ahead the shoe is pushed towards the discharge while the rebounding hose behind the shoe draws more fluid in. With 100% compression at all times, the pump provides stable metering accuracy and pressure performance. With no pump seals or valves, abrasive or aggressive fluids are safe to be pumped as fluid to contact only the inner wall of the hose.


Key features

1.Suction height is up to 9.1m and very strong self-priming

2.Dry-run definitely is allowed without damage

3.Ideal for shear sensitive or high viscosity fluids

4.Good solution for acids, large solids and abrasive fluids

5.Very easy maintenance – just change the hose

6.Hose material option: NR, NBR, EPDM


Performance range

-Capacity: 96 m3/h

-Pressure: up to 9 bar

Sliding vane pump

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.


Key features

1.Good self-priming ability (up to 5m within 20 second)

2.Liquid-gas phases applicable pumping (gas Max.48%)

3.Dry run allowable up to Max 8 min

4.Slip-fit vanes to ensure pump performance against wears

5.Easy maintenance (simple vanes change procedure)

6.Applicable for volatile organic fluids as non-metal with non-metal contacts


Performance Range

-Capacity:3-200m3/h

-Pressure: Max.10bar

-Temperature: -35 to 75 ℃

Reciprocating plunger pump

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.

Key features

1. three or five cylinders available

2. API 674 standard compliance


For details, contact sales@shenmech.com


Performance range

- Pressure: Max.180 MPa

- Capacity: 118 m3/h

- Temperature: up to 400 ℃

- Plunger stroke: 818 mm




Double diaphragm pump

General introduction

Air diaphragm pump is driven by compressed air, Air enters the air valve which will allow pressurized air into one of the two chambers. As the air enters and fills the chamber on the left, the flexible diaphragm expands and compresses the fluid on that side of the diaphragm. This to force the upper valve to open, releasing the fluid into the discharge pipe. It is called the “discharge chamber” at this point of the pumping cycle. At the same time when the discharge chamber is pumping liquid out of the pump, the opposite diaphragm is pulled in toward the center housing by the drive shaft. Negative pressure is generated in that fluid chamber lifting the lower valve which draws fluid into this chamber, this is the “suction chamber” of the pumping cycle.As soon as this “suction chamber” diaphragm makes contact, the air pilot pin is forced across the center housing, air exhausts to atmosphere from the discharge chamber, at the same time compressed air enters the “suction chamber” and the pumping action is reversed. The vacuum side becomes the pressure side and vis versa.


Key features

1.Integrated center housing for compact pump structure

2.Module design of external air valve for easy maintenance

3.No dynamic sealing and can dry run

4.Low shear force to maintain fluid’s material structure

5.Chance pump capacity and head by adjusting compressed air’s amount and pressure

6.Pump driven by electric motor is available


Performance range

-Capacity: Up to 64 m3/h

-Pressure: Max.8.1 bar

-Particle allowable: Max.5.8 mm
