Marine Utility Pump

The Dayton 1P811 is a 12V DC marine utility pump rated for potable water systems. It delivers a maximum flow rate of 6 gpm and a shut-off head of 14 ft. The unit operates within a media temperature range of 40 to 160 degrees F and draws 2 A. It is designed for marine and general utility applications.

Hardwired Installation and Connections

The pump requires a hardwired 12V DC electrical connection for power. It features MNPT threads on both intake and discharge ports, compatible with 1/2 in intake and 3/8 in discharge pipe sizes. This configuration allows direct plumbing into existing water systems without proprietary fittings.

Capacity and Headroom

The pump provides a maximum discharge pressure of 6 psi and handles up to 14 ft of head. It comfortably moves water in typical bilge, transfer or circulation tasks within that pressure envelope. Flow will drop to zero at the 14 ft shut-off limit, so it is not suited for high-lift or high-pressure demand.

Questions about this item

What is the maximum head pressure the 1P811 pump can overcome?

The pump is rated for a maximum of 14 ft of head and a shut-off level of 14 ft.

How much current does the motor draw during continuous 12 V DC operation?

The motor draws 2 A at 12 V DC; heat will build from motor and fluid friction, and the pump produces audible motor noise while running.

What pipe sizes must already be on the system for the MNPT connections to fit?

The discharge port accepts 3/8 in compatible pipe and the intake port accepts 1/2 in compatible pipe, both with male NPT threads.
