APPLICATIONS
The PAR-MAX Automatic Water System Pump is
designed for self-contained boats and RV's with multiple
fixture water systems. The system operates auto-
matically. When a fixture is opened, the pump instantly
begins operation to provide a smooth constant flow from
tank to faucet. Closing the faucet automatically discon-
tinues pump operation.
The Deluxe model 31630-Series has a corrosion
resistant coated motor for extra protection in harsh
environment applications.
