Pentair 2088-394-144 Diaphragm Spray Pump 1/15 Hp

Product Description

The PENTAIR 2088-394-144 is a diaphragm-style spray pump designed for on-demand liquid transfer and spray applications. Rated at 1/15 horsepower and powered by 115-volt AC current, it delivers up to 3.6 gallons per minute (GPM) at a maximum working pressure of 45 psi. The pump body is constructed from polypropylene, providing resistance to corrosion and chemical exposure. Both the inlet and outlet connections measure 1/2 inch. An integrated demand switch automatically cycles the pump on when flow is called for and shuts it off when downstream demand stops, reducing wear and power consumption. Licensed plumbers and irrigation technicians are the primary installers.

This pump suits residential and light commercial spray, chemical dosing, water transfer, and pressure-boosting installations where a compact, self-priming diaphragm design is appropriate. The demand-switch feature makes it a common choice for RV water systems, marine freshwater delivery, agricultural chemical sprayers, and small-scale irrigation setups. The polypropylene construction is compatible with a broad range of treated water and mild chemical solutions. Verify chemical compatibility with polypropylene before use in aggressive media applications.

Key Features

• Diaphragm pump design supports self-priming and dry-run tolerance typical of this pump type
• Integrated demand switch starts and stops the pump automatically based on downstream flow demand
• 3.6 GPM maximum flow rate suitable for spray, transfer, and pressure-boost applications
• 45 psi maximum working pressure
• Polypropylene body resists corrosion and a wide range of mild chemical solutions
• 1/2 inch inlet and 1/2 inch outlet for straightforward plumbing integration

Compatibility

Designed as an OEM-style diaphragm spray pump for residential and light commercial spray and liquid-transfer systems requiring a 1/2 inch inlet and outlet, 115-volt AC supply, and on-demand operation up to 3.6 GPM and 45 psi.

Installation Notes

Installation should be performed by a licensed plumber or qualified technician familiar with low-pressure fluid systems. Shut off the water supply and disconnect electrical power before servicing or replacing the pump. Secure all fittings to the rated torque specifications provided in the pump manufacturer documentation and verify that system pressure does not exceed the 45 psi maximum working pressure rating. Follow applicable plumbing codes, including IPC guidelines, for potable water or chemical-handling installations.
