AL Industrial Rotary Lobe Pump is Versatile

Take a proven design with tight manufacturing tolerances, offer multiple lobe styles and seal options, and you have the AL Industrial Series positive displacement pump.

Derived from the AL Sanitary Series, the AL Industrial Rotary Lobe Pump carries the same 3A and EHEDG Sanitary Certifications for hygienic applications.

Embraced by the chemical industry, the AL is in processing applications around the world. The AL’s 316L stainless steel construction and non-contacting lobe design provide back-face tolerances as precise as .006”/.1524mm.

Low pulse pumping of shear sensitive products like dimethanolamnine and polyvinyl acetate is achieved through the variety of seals and lobe options.

Multiple rotor designs are available including single wing, double wing, tri-lobe and multi-lobe. The standard rotor material is 316L stainless steel with optional Alloy 88 and Nitronic 60 available.

The AL Series offers 6 seal options including the double mechanical seal with flush ports to extend seal life and increase processing uptime. Contact Ampco’s application engineers today to discuss how the AL Series can fit your application requirements.

All AL Industrial  Rotary Lobe Pumps come standard with a 304 stainless steel gearcase, 150# flange connections – predrilled for flush, and offer a front-loading seal design making them a maintenance department favorite.
