The Leistritz L3 Re-Engineered Pump gives you a drop-in replacement that may cost less than repairing your existing pump. This can replace any brand of three screw pumps, generally at a better price and delivery than other OEMs. The Leistritz Re-Engineered Pump utilizes a standard 3-Screw Pump Cartridge with a fabricated casing to match your existing footprint and piping/driver connections. The modern 3-Screw Pump Cartridge has only one mechanical seal, one bearing and no wear components, thus assuring reliable, efficient operation.
