KSB Etaprime

Product features

The self-priming Etaprime is perfect for pumping pure, contaminated and aggressive liquids without abrasive and solid components.

KSB’s Etaprime is a versatile pump for the most diverse of applications:

The self-priming Etaprime pump is a trendsetter in many aspects. We have compiled a summary of the versatile pump’s many benefits for you:

After the pump casing has been primed with the fluid to be handled, Etaprime is self-priming with a suction lift of up to 9 metres.
The pump is insensitive to the penetration of gas and air.
Etaprime is very service-friendly. Its robust KSB IE3 motor complies with the IEC 60034-30 standard.
Its replaceable shaft sleeve prevents wear on the shaft.
Provided with an inspection hole, the pump is easy to clean.
A foot valve may not be required under certain circumstances.
Etaprime pumps can be dismantled without removing the casing from the piping.

The horizontal, self-priming Etaprime volute casing pump is available in the following designs:

Etaprime L: This pump is designed with a torsion-resistant baseplate, made of sectional steel, for the complete pump set (pump and motor). It provides connection options for temperature and shock pulse measurement. Etaprime L can be supplied grease-packed for life or with oil lubrication (constant-level oiler or oil level gauge).
Etaprime B: In this design version, the pump shaft is rigidly connected to the motor shaft. This is a close-coupled pump without a separate coupling, so no manual alignment is required.
Etaprime L/B: For demanding fluids both pump designs are available in either grey cast iron or stainless steel. The smallest pump sizes come with a screwed pipe connection (to ISO 7-1 as standard, on request drilled to ASME B1.20.1). All other pump sizes are designed with a flanged end (standard to EN 1092, on request drilled to ASME B16).
