Leo LEP100-80-200 Bare Shaft End Suction Centrifugal Pump Only
12275
The LEO LEP100-80-200 is a bare-shaft end suction centrifugal pump built to the European standard BS EN733 / DIN 24255. It has a DN100 suction and DN80 discharge flange and a 200 mm nominal impeller, in a horizontal, single-stage, back pull-out volute design. This is the pump only: it is supplied without motor, coupling or base plate, so it can be matched to a 2-pole (2900 rpm) or 4-pole (1450 rpm) motor for the duty point you need.
Back pull-out construction lets the rotating assembly be removed for servicing without disturbing the suction and discharge pipework. Typical uses are water supply, pressure boosting, HVAC heating and cooling circuits, industrial process water and fire-fighting systems.
