Progressing cavity pumps for viscous fluids & slurries
Progressive cavity pumps are a type of positive displacement pump, also referred to as a helical rotor pump, a mono pump or an eccentric screw pump. Thanks to their ability to handle viscous fluids, slurries, liquids that contain large particles, gas-liquid mixtures and sheer sensitive fluids, the progressing cavity pump is a popular type of pump for potentially tough applications when other pumps may fail.

FAQs
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.
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.
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.
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.
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.
