Why use a progressive cavity pump?

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.

What are progressive cavity pumps used for?

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.

Are progressive cavity pumps self priming?

Yes! A progressive cavity pump's tight tolerances mean it has excellent suction capabilities.

Can progressive cavity pumps handle solids in my fluid?

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.

Can these pumps be supplied with hopper?

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.

Can progressive cavity pumps run dry?

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.

The Nova Rotors DX/JX series of sanitary progressive cavity pumps are the hygienic range of helical rotor pumps within the Diamond series. The series, which consists of models DX, JX, DXO and DXC are state of the art mono pumps for the handling of viscous, shear sensitive and solids in the food processing, pharmaceutical, chemical and cosmetic industries. Designed for the pumping of wine, dairy and beverages, and with typical applications in breweries, distilleries and the tomato and sugar industries, these hygienic progressing cavity pumps have a complete sanitary design and comply with EHEDG and 3A standards, ensuring maximum sanitation and clean in place capabilities.

Specifically designed to allow drainage and avoid dead zones, these Nova Rotor progressive pumps are top rated, with each component manufactured to the highest level finish and cleanliness.

DX Series: Drive is directly coupled to the eccentric screw pump via a flange. A cheap and compact solution, with reduced installation costs and simplified maintenance.

JX Series: Drive is connected to shaft inlet via coupling joint. Best solution for performance and durability. Requires greater installation space.

DXO & DXC: Solutions with the best sanitary characteristics, due to it being free of dead zones and stagnation. Both suitable for abrasive fluids.

DXO Series: Open joint hygienic pump meaning guaranteed lubrication and long duration. Pumping lubricant products improves performance considerably.

DXC Series: Hygienic pump with patented pin joint.

For more information on the working principle and typical applications, read our progressive cavity pump guide.

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.
