Innovative Etabloc Pump range from KSB with intelligent design

This April, German pumps and valves specialists KSB release the latest incarnation of their enduring Etabloc pumps series, taking specifications to the next level thanks to a raft of intelligent design features and an extended range of pump sizes. PIF looks at some of the advantages of this new innovation.

Diverse materials and seal variants

Choose from a range of materials comprising cast iron, bronze, stainless steel and nodular cast iron. This diversity of materials and a large choice of seal variants has extended the suitability of the new type series to applications beyond just water. Plus, confined gaskets ensure reliable sealing between pump casing and casing cover, even in highly varying operating conditions.

The space allocated to the mechanical seal has been enlarged to enhance venting in this area. Single or double mechanical seals to EN 12756 are standard and special variants – like mechanical seals in tandem or back-to-back arrangement – as specific applications dictate.

Service-friendly design

Another feature of the updated Etabloc pumps series is its new, spacious and service-friendly design that facilitates dismantling and reassembly of the mechanical seals. The conical seal chamber, for example, allows easy access and provides more space for maintenance work.

Easy-to-replace casing wear rings protect the impeller and the casing cover from wear and the drive lantern comes in standardised mating dimensions, offering the operator maximum choice in selecting an electric motor. Plus, forcing screws provided at the lantern make dismantling of the drive train much easier.

Clever discharge nozzles

Discharge nozzles are fitted with more connection options for pressure gauges, so several measurements can be conducted simultaneously. The flanges of suction and discharge nozzles – in all materials – are optionally drilled to EN 1092 or ASME dimensions and a large variety of nozzle positions, and installation options, enables maximum flexibility.

Wide variety of pump sizes

KSB's newly enhanced series proudly boasts up to 43 pump sizes, which can be driven by either 2-pole or 4-pole motors. With further additions to the selection chart, the pump size can now be selected even closer to the best efficiency point.

Impeller trimming as standard

Every pump from KSB comes supplied with the impeller diameter trimmed exactly to the duty point. Combined with the large range of pump sizes available for selection, impeller trimming is the only way of keeping the pump set's energy consumption to a minimum.
