Single Screw Progressive Cavity Pump – Technical Data Sheet
Product Description
The single screw progressive cavity pump is compact, easy to maintain, and suitable for a wide range of light and heavy fluids. It delivers stable flow with minimal pressure fluctuation and strong self-priming ability.
The stator is made from food-grade elastomers (NBR, silicone, FKM), while the rotor and casing are manufactured from 304/316 stainless steel, ensuring safety in handling food, pharmaceutical, and chemical products.
The pump is ideal for transferring high-viscosity fluids and semi-solids such as tahini, hummus, honey, molasses, syrups, creams, oils, emulsions, suspensions, and more.
Working Principle
Single screw, progressive cavity pump.
Fluid advances through sealed cavities formed between the rotor and stator in a continuous spiral motion.
Flow rate is proportional to the pump’s rotational speed.
Main Features
-
Stable, non-pulsating flow.
-
Handles both low and high viscosity fluids.
-
Capable of pumping fluids containing soft solids or fibers.
-
Hygienic design with food-grade materials.
-
Easy operation, cleaning, and maintenance.
-
Long service life and wear resistance.
