Sanitary Progressive Cavity Pumps

No! Even short period of dry running can result in damage to the rotor and stator, making dry run protection a must if there is risk of this.

Our progressing cavity pumps can be supplied with auger feed allowing non-flowing mediums such as dry sludge and waste matter to be pumped without clogging. We can also provide liquid injection ports which are popular when liquid waste is added to dry content waste to allow it to flow.

Yes they have excellent solid handling capabilities! However, it should be noted that abrasive fluids e.g. low viscosity/water based fluids containing solids may cause shorter stator wear.

The design is best suited to highly viscous and lubricating fluids including oils, sludges, waste matter, biomass, pastes and grape pressing that may contain very large solids, as well as pumping viscous products over long distances.

Their pressure capabilities and viscosity handling is unrivalled, which means that whilst they are quite expensive in design and large in footprint, they are often selected for applications when all other pumping technologies will fail.

It consists of a spiralled helical rotor (like a cork screw) that sits tightly inside a rubber stator/sleeve. As the rotor turns inside the stator, it forms a set of fixed-shaped cavities that progress along the length of the stator and force the fluid inside to move along with them as they turn.

The FDA states that in order to be food grade, the food contact surfaces of a hygienic pump need to be smooth, free of cracks and crevices, non-absorbent, cleanable, non-toxic and corrosion resistant to ensure that no food or bacteria can harbour and contaminate the product.

All products that we offer for food, cosmetics and pharmaceuticals are as a minimum constructed of FDA approved materials for human consumption. Where more stringent approval is required, we also offer pumps certified to 3A and EHEDG.
