Selection and Quotation
Send the required flow rate, total head, liquid composition and temperature, installation conditions and quantity. Model-specific flow rate, head, motor power, connection size and dimensions will be confirmed with the quotation.
Selection resources for the ISW series
Review the ISW horizontal arrangement against the available installation and the required clean-water duty. Matching nominal flow and head is one part of the decision; the actual inlet, discharge, base and connection dimensions also need to be checked.
- HVAC circulation applications — connect the loop requirement to the proposed installation.
- Building pressure boosting — prepare the inlet condition and required flow/head duty.
- ISW and ISG comparison — review orientation, piping and maintenance access.
What should I send when replacing a horizontal pump?
Send the existing nameplate and installation details, plus the duty you need to achieve. Request the proposed ISW model's performance curve, connection layout and dimensional drawing, and review these against the pipework, base and electrical supply.
Use the pump RFQ checklist to record the requirement and the purchasing FAQ for document and order questions.
ISW catalogue reference points
For the horizontal ISW offering, the manufacturer groups ISW/IHW with ISG/IRG/IHG in a shared performance table. The selected printed codes below do not establish identical pipe connections, dimensions or interchangeability. Confirm the complete ISW designation with the quotation.
| Printed model code | Flow Q (m³/h) | Head H (m) | Motor power (kW) | Speed (r/min) |
|---|---|---|---|---|
| 40-125 | 6.3 | 20 | 1.1 | 2900 |
| 50-160 | 12.5 | 32 | 3 | 2900 |
