4 Product Advantages at a Glance Self-priming after the pump casing has been filled with the fluid handled Excellent suction behaviour, self-priming up to 9 m; no foot valve required Pump unit is insensitive to the penetration of gas and air Double-acting mechanical seal available for tough applications High operating reliability due to sturdy deep-groove ball bearings UG26676:0/1 Inspection cover for easy cleaning Shaft sleeve prevents wear on the shaft Back pull-out design: thecasingmayremain in the pipeline when the pump is dismantled Reliable, maintenance-free mechanical seal Sturdy support foot; even in the case of external forces the shaft is only slightly displaced in the coupling area
