Pump Replacement Checklist: Liquid, Head, Flow and Connections

Black submersible water pump with outlet fitting

Replacing a pump requires the application and operating conditions, not just the old pump's wattage. Record the liquid, required flow, head and connections before comparing replacements.

Build a replacement record

Photograph the identification plate and note the original model. Describe the system, including vertical lift, pipe route and any control arrangement. Confirm whether the pump handles clean water, specified dirty water or another permitted liquid.

Detail What to match
Performance Required flow at the actual operating head
Connections Size, thread and approved pipe arrangement
Materials Compatibility with the liquid and temperature
Controls and supply Intended switching, power and installation requirements

Compare the operating point

Maximum flow and maximum head should not be assumed to occur together. Use the performance curve and appropriate technical advice. A physically similar pump can be unsuitable for the original duty or installation. Plumbing, electrical and specialist applications may require qualified installation. Do not adapt an unsuitable connection or use a general pump for drinking water or chemicals without explicit support. Choose from a complete replacement specification and retain it for future servicing.
