An exclusive design that combines the high flow of a centrifugal pump with the pressure producing and self-priming capabilities of a positive displacement pump. The Series Varna's magnetic drive means no shaft seals leak, run hot or wear out. Material construction consisting of 100% engineered plastic ensures that fluids will not come into contact with any metallic parts. The pump operates at low speeds with a quiet, gentle, low-shear, non-pulsing action.
