End-Suction Water Pump construction and operation

End-Suction Water Pump: illustrative pump assembly and construction

Horizontal end-suction, back-pull-out construction

The impeller transfers energy to the liquid through the pump casing. Final selection depends on the model curve, liquid properties, sealing arrangement, drive and piping conditions.

An end-suction pump for clean water and similar liquids in supply, circulation, boosting and irrigation duties.

  • Single-stage single-suction end-suction construction
  • Back-pull-out arrangement needs rear maintenance access
  • Clean water and similar liquids; check the specific model table

applications

Typical applications

Application illustration: industrial cooling-water circulation

water supply

For water supply, state demand, pumping water level, source quality and seasonal operating range. Check the proposed arrangement against horizontal end-suction arrangement and wetted materials selected for the liquid and temperature, then verify the operating point on the selected model curve.

circulation

For circulation, define design and part-load flow, required differential head, water temperature and the resistance of the circuit. Check the proposed arrangement against horizontal end-suction arrangement and wetted materials selected for the liquid and temperature, then verify the operating point on the selected model curve.

pressure boosting

For pressure boosting, provide inlet pressure, target outlet pressure, peak demand, control method and the number of operating zones. Check the proposed arrangement against horizontal end-suction arrangement and wetted materials selected for the liquid and temperature, then verify the operating point on the selected model curve.

irrigation

For irrigation, state demand, pumping water level, source quality and seasonal operating range. Check the proposed arrangement against horizontal end-suction arrangement and wetted materials selected for the liquid and temperature, then verify the operating point on the selected model curve.

questions

End-Suction Water Pump FAQs

How do I select a model?

medium name and composition; required flow; total head; operating temperature; suction conditions; installation arrangement; power supply and drive method; materials, standards and inspection requirements; required supply scope. Review the complete duty on the applicable model curve.

Which materials and sealing can be supplied?

Wetted materials selected for the liquid and temperature. Packing or mechanical seal, as selected. Confirm compatibility with the complete liquid composition and temperature.

Are catalogue model references guaranteed duty points?

Catalogue ranges summarize printed records and may combine different conditions. Check each model against its source curve and required speed.

What is included in the delivery?

Confirm pump, driver, controls, auxiliaries, spares, drawings, manuals and required test records in the agreed quotation.
