Solving Problem Applications > ■ Designed to pump liquids that challenge other pumps, includingshear-sensitive liquids, liquids with solids, low lubricity liquids, and high viscosity liquids. > ■ Pump materials available to accommodate corrosive, abrasive,or high temperature liquids. > ■ Excellent for self-priming and suction lift applications. The Pumping Principle > ■ Pumping elements are bi-wing rotary lobes that provide agentle, non-shearing, low pulsation pumping action. > Packed Gland (RL016 & 025) ■ Liquid feeds the lobes from three sides to provide excellentsuction performance on viscous...

Seal chambers vented tomaximize seal performance.Labyrinth seals standard to isolatebearing housing from contaminants.Rigid shaft support on bothsides of seals minimizes wear, extending seal life. > Fluid access on three sides oflobes enhances filling with highly viscous fluids.A variety of port sizes, flange ratings,and styles are available to match the ports to the system requirements. Patented adjustable cartridge-stylebearing housing provides simple end clearance adjustment.Direction offlow is reversible for loading / unloading applications. Easy timing,with no shims or special tools required....
