Progressive Cavity Pump Seals

Progressive cavity pumps are a unique type of rotary positive displacement pumps. Their sealing area geometry and mechanical arrangement are distinctive, rendering the use of ordinary cartridge seal impractical or complex. Furthermore, they are used mostly for pumping of pastes and slurries at low speeds, making the operating conditions nonstandard. Ettem sealing solutions for such pumps are pump specific and are offered in a variety of material combinations.
