SHURflo Revolution 4008 Water Pump Exploded Parts Diagram & Repair Kits

The SHURflo Revolution 4008 fresh-water pump can be serviced with specific head, valve, check-valve and pressure-switch components. Use the numbered Pentair exploded diagram to identify the failed assembly, then match the complete model number on your pump: the 12V, 24V and 115V versions use different motors.

Identify your Revolution 4008 pump

These three complete-pump listings show the different electrical versions. Pentair lists 3 GPM flow and a 55 PSI nominal shutoff rating for the models below; confirm the electrical rating on your old pump's label.

Check compatibility before ordering

The 12V 4008-101 series uses motor 94-11-302-00, the 24V 4008-131 uses 94-11-303-00, and the 115V 4008-171 uses 94-11-306-00. Do not interchange motors between voltage versions. The 4028 family uses a different upper housing, drive, complete head and switch even though the 94-800-01 valve assembly and 94-800-03 check valve also appear in its Pentair service table.

Repair safely: Disconnect the pump from power, relieve water pressure and isolate the fresh-water supply before removing a pump head or switch. The factory diagram identifies parts, but does not replace the installation and servicing instructions for your exact pump.
