Application Details:

• Pump / Service Type: Complete mechanically driven bronze flexible-impeller pump

• Always compare the removed impeller or pump against the listed dimensions, drive style, material and housing depth before installation.

🔌 Function

The complete flexible-impeller pump uses rotating flexible vanes to create suction and move fluid through the bronze pump body. Correct voltage, capacity, port orientation, mounting and impeller material are all required for safe operation.

Common signs replacement or service is required:

• Pump will not prime or repeatedly loses suction

• Reduced flow, pressure or deck-wash performance

• Motor runs but little or no fluid is discharged

• Pump overheats, draws excessive current or trips thermal protection

• Fluid leaks from the shaft seal, cover or port connections

• Impeller has been damaged by dry running or incompatible fluid

📦 Condition

• Brand-new aftermarket replacement pump assembly

• New and unused

• Supplied in suitable manufacturer or equivalent protective packaging
