Hybrid Hygienic Centrifugal Pumps

Overview

The Sawa LES series stainless-steel hybrid centrifugal pumps are an excellent alternative to side channel pumps. They have a specially developed pump cover with an inducer and an integrated recirculation system, thus allowing it to be used successfully as a self-priming pump.

Typical applications include loading/unloading and CIP supply/return.

Suitable for foodstuffs, bevereages, alcohols, oils, solvents, emulsions, pharmacutical products, chemicals, fruit juices, fruit pulp, beer, cooking oil, fats.
