Self-priming centrifugal pumps revised
KSB launched the latest versions of its self-priming centrifugal Etaprime pumps. The pump sets offer good suction properties, also under relatively poor inlet conditions. They deliver even if the inlet pressure is low. At negative inlet pressure, for example, the pumps still manage up to 9 m suction lift. Fluids with entrained gas can also be handled, while it is not necessary to install a foot valve. The pump sets are designed for handling fluids of temperatures between -30 and +90 °C. Their maximum head is 105 m and the flow rate can come up to 180 m³/h. The type series comprises 28 sizes, which can be driven by either 2-pole or 4-pole IE3 motors. The pumps are available in compact close-coupled design or as classic baseplate-coupling-motor versions. All mating dimensions are fully compatible with those of the previous generation. The customer can choose between oil-lubricated rolling element bearings or those grease-packed for life. It is also possible to provide connections for temperature or shock pulse sensors on the bearing brackets.
