The SP-LR self-priming liquid ring pumps are specially designed for pumping liquids with a high air or gas content. An excellent example of this are CIP-Return applications in the food-, dairy-, beverage- and pharmaceutical industry.
All liquid touching parts of the SP-LR pumps are compliant with the relevant standards. The open impellers are provided with pressure relief holes, which at the same time ensure an optimal cleaning of the shaft seal and the seal chamber. The impeller is ‘dry’ mounted to the shaft by means of O-rings. The applied O-ring constructions are designed to minimise the liquid contact and at the same time to provide an optimal cleaning of the contact faces.
Depending on the application range, but always compliant with the hygienic standards, the SP-LR-line can be executed with several options:
