Visflow Helical Pumps are manufacturer of Self-Priming Progressive Cavity Positive Displacement Pump. It consists of Two Elements: A Rotating Single Helical Rotor & A Double Helical Stationary stator. The medium is conveyed with low pulsation and turbulence. In the conveying of abrasive media an advantage is achieved by the flexible choice of materials for the rotor and stator. The flow rate is proportional to the speed of rotation. Increasing the number of stages raises the pump pressure proportionally. The design allows pumping in both directions, a high suction lift and gentle conveying. Due to the numerous combinations of materials for rotor and stator and the gentle conveying with extremely low shear forces, these Progressive Cavity Pumps are also highly suitable for transferring and metering tasks.
