KSB Expand Range of Water Pumps

KSB report it has responded to the increase in the volume flow rates demanded of pumps installed in water transport systems by expanding its RDLO type series from 21 sizes to 33.

The pump sets are axially split volute casing pumps primarily used for clean water transport. The company add that their extreme durability is the main reason why they are used in pumping stations all over the world. A casing with double volute compensating radial forces and a double-entry impeller compensating axial forces are key to a long service life. As a result, the generously dimensioned rolling element bearings are subjected to a minimum load only. Excellent efficiencies guarantee low energy costs over the pumps’ entire service life.

KSB state that low-vibration operation is ensured by solid bearing brackets bolted to the upper part of the casing and a rigid shaft. The loads on the rolling element bearings, the mechanical seals and the coupling between pump and motor are thus significantly reduced. Ease of service played an important role when designing this type series. The self-centring upper part of the casing and the spring-loaded rotor enable cover and rotor mounting without any further adjustments.
