Progressive Cavity Pump SESP35, Superior Hygiene

Introduction of Hygienic Progressive Cavity Pump

The hygienic progressive cavity pump is a kind of positive displacement rotor pump. It relies on the volume change of the sealed cavity formed by the screw and the bush to suck and discharge the liquid. This type of pumps does not form eddy current when pumping medium. It is not sensitive to liquid viscosity and can pump high-viscosity medium. SeFluid’s hygienic progressive cavity pump series has the advantages of simple structure, safe and reliable operation, convenient use and maintenance, continuous and uniform liquid discharge, and stable pressure.

Principle of Hygienic Progressive Cavity Pump

When the motor drives the pump shaft to rotate, the screw rotates around its own axis on the one hand, and on the other hand it rolls along the inner surface of the bushing, thus forming the sealed chamber of the pump. The liquid in the sealing cavity advances one pitch for each revolution of the screw. With the continuous rotation of the screw, the liquid is pressed from one sealing chamber to the other sealing chamber in a spiral shape, and finally squeezed out of the pump body.

Features of SeFluid's Hygienic Progressive Cavity Pump

1

Low inertial force of the rotating parts, ideal for very high speed.

2

Less sensitive to incoming gas and dirt than other rotary pumps.

3

Uniform and continuous flow, small vibration and low noise.

4

No end-flow pulsation and pulsation; smooth running and flow rate.

5

Forward and reverse double running directions.

6

Ability for pumping multi-phase fluid mixed with liquid, gas and solid.

7

Outstanding ability of suction and self-priming.

8

Sanitary design with flash protection cover.

9

Viscosity of the pumped fluid can reach 50000 cps and the solid content can reach 50%; Can pump fluid with solid.

10

Wide range of pressure and flow. The pressure is about 3.4-340 kgf/cm², and the flow rate can reach 18600 cm³/min.

11

The spiral sealing line completely separates the suction cavity and the discharge cavity, so that the pompa monovite igienica has the same isolation function as a valve.

Advantages of Hygienic Progressive Cavity Pump

Compared with Centrifugal Pumps

Hygienic progressive cavity pump does not need valves, and the flow is a stable linear flow.

Compared with Plunger Pumps

It has strong self-priming ability and higher suction height.

Compared with Diaphragm Pumps

This type of pumps can transport various mixed impurities, such as media containing gas and solid particles or fibers, and can also transport various corrosive substances.

Compared with Gear Pumps

Hygienic progressive cavity pump can transport substances with high viscosity. Furthermore, unlike plunger pumps, diaphragm pumps and gear pumps, progressive cavity pumps can be used for pharmaceutical filling and metering.

Applications of Hygienic Progressive Cavity Pump

Hygienic progressive cavity pump is widely used in the food, beverage, and pharmaceutical industries for the transfer of liquids and viscous materials. This type of pumps is designed to handle fluids with high viscosity and are ideal for gentle handling of delicate fluids, shear-sensitive liquids, and those containing solids or abrasive particles. Some common applications include:
