The AL Series Rotary Lobe Pump is the Low Cost, Big Technology Leader

The AL Series offers big value to the positive displacement pump market. This pump offers high level technology and performance – at an economical price.

Ampco’s AL is well-suited for a variety of applications in the food, dairy, beverage and pharmaceutical industries with viscosity ranges from 1 to 1,000,000 cP and self-priming capabilities up to 12 feet.

There are several optional features in the AL Series line-up providing maximum flexibility for each application.

Seal choices include: double mechanical, mechanical seal with flush, double lip seal, triple lip seal, O-ring, and double O-ring. Heating and cooling jackets for temperature sensitive processing are available.

Multiple rotor options are a tremendous advantage to the AL Series. Four rotor configurations – single or double wing and tri or multi-lobe – allow users to customize the AL to their specific application requirements.

All AL pumps are 3A and EHEDG certified.

As with all Ampco positive displacement pumps, the AL Series offers a stainless steel gearcase. Add to that a front loading seal design with superior CIP-ability and ease of maintenance, and you have the best value in rotary lobe technology.
