KSB now offers a slide rule type selector that helps to size and select floodable sewage lifting units for building services applications.

According to KSB, the front side of the slide rule serves to establish the flow rate Q and discharge head H required for selecting the pump. Functions also include establishing the design units (DU), sizing the piping as well as calculating the head losses in piping, valves and fittings.

With the slide rule’s rear side it is possible to select the optimum pump hydraulic system on the basis of the flow rate and discharge head. In addition, the user can calculate the discharge pipe’s volume and the tank size as a function of the suction head.
