Installation & Selection Tips
Confirm your electrical supply matches three-phase requirements. Ensure suction and discharge piping matches the listed NPT sizes to support the rated capacity range. Verify that the required duty point falls within the listed 40–190 GPM and 70–170 ft head performance range.
For cooling tower, HVAC circulation, water transfer, or booster service, confirm the system flow rate, total dynamic head, fluid temperature, suction conditions, and available NPSH before ordering. For complete boiler room packages, see our condensate return systems.
