Rovar progressive cavity pumps are ideal for pumping neutral or slightly corrosive liquids, contaminated or abrasive liquids, liquids with gases or forth, liquids of low or high viscosity, liquids containing fibrous, semi-solid, or solid particles.
These pumps consist of the single-threaded metal screw which rotates eccentrically within a double helix vulcanized rubber stator, of twice the pitch length of the stator. On rotation, the rotor screw creates mobile chambers/cavities which progress towards the discharge end carrying the pumped material. The pumping product is conveyed or transferred without being churned or changing the properties of the product.
Self-priming even with entrained air.
The capability of pumping very high viscous products.
Shaft seal flexibility.
Minimal damage to shear sensitive liquids.
Low NPSHR, Pulsation free.
Can handle liquids with solids or abrasive particles.
Externally housed bearings.
Wide throat inlet with anger for very high viscous non-flowable media.
Easy cleaning with CIP ensuring complete self-emptying.
