How to identify pumps
Pumps move fluid by adding energy — pressure, flow or both.
Have one in front of you? Photograph it and get an evidence-backed identification.
Identify from a photoIdentification clues
- —Name plate: model, flow, head, speed, serial
- —Casing geometry (volute, inline, close-coupled)
- —Inlet/outlet sizes and orientation
- —Drive arrangement and motor frame
- —Seal type visible at the shaft
Common types
- —Centrifugal end-suction
- —Inline
- —Gear
- —Vane
- —Diaphragm
- —Peristaltic
- —Submersible
Typical failure modes
- —Mechanical seal leakage
- —Bearing failure
- —Cavitation erosion
- —Impeller wear
- —Misalignment vibration
What a replacement must match
- —Match duty point (flow and head)
- —Match connections and footprint
- —Match materials to the fluid
- —Confirm motor and speed
Photos that help identification
- —Photograph the name plate clearly
- —Show inlet and outlet
- —Show the shaft seal area
