applications

Typical applications

Application illustration: industrial cooling-water circulation

building water supply

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

pipeline boosting

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

HVAC

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

hot- and cold-water circulation

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

questions

Vertical In-Line 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.
