Electric pressure booster pump unit IH11

centrifugalmulti-stage

Inline pressure boosting pumps IH11 are multi-stage centrifugal pumps with suction and discharge ports arranged on the same axis (inline). They operate with closed impellers, achieving optimal hydraulic performance with low motor power. These pumps are not self-priming. With opposing suction and discharge ports, the pumps can be installed in horizontal pipelines or connected directly to the tank. The IH series is suitable, for example, for supplying coolant to internally cooled tools.
