Pentair 8020-513-236 Diaphragm Spray Pump 1/10 Hp

Product Description

The PENTAIR 8020-513-236 is a diaphragm spray pump designed for on-demand liquid transfer in spray and dispensing applications. Rated at 1/10 HP and powered by 115 volts AC, it delivers up to 1.4 GPM with a maximum working pressure of 60 psi. The pump body is constructed from polypropylene, making it resistant to many chemicals encountered in agricultural, horticultural, and light industrial spray systems. It features a built-in demand switch that automatically starts and stops the pump based on downstream pressure, eliminating the need for a separate pressure switch or manual control. Both the inlet and outlet ports are 3/8 inch, allowing straightforward connection to standard tubing or fittings.

This pump is suited for residential and light commercial spray applications where a compact, self-priming diaphragm pump is required. Typical installations include spot sprayers, boom sprayers, chemical metering systems, and irrigation dosing setups. The demand switch operation makes it a practical choice for systems where flow is intermittent and consistent pressure control is needed without continuous operator intervention. Licensed plumbing or irrigation contractors and knowledgeable service technicians typically handle installation in fixed systems.

Key Features

• Demand switch provides automatic start and stop based on system pressure
• Polypropylene pump body offers resistance to common spray chemicals
• 1.4 GPM maximum flow rate suits low-volume spray and dispensing applications
• 60 psi maximum working pressure supports a range of spray nozzle types
• 3/8 inch inlet and outlet ports for straightforward plumbing connections
• Diaphragm pump design handles moderately viscous and particulate-laden fluids better than centrifugal alternatives

Compatibility

Designed as an OEM-style replacement or direct-install diaphragm spray pump for on-demand spray and chemical dispensing systems requiring a 3/8 inch ported, 115-volt AC pump with demand-switch operation.

Installation Notes

Disconnect and lock out power to the circuit before servicing or replacing this pump. Verify that supply voltage matches the 115-volt AC requirement before energizing. All plumbing connections should be sealed with appropriate thread sealant rated for the fluid being pumped, and tubing or pipe must be rated for at least 60 psi working pressure. Installation in chemical dispensing or agricultural spray systems should comply with applicable local codes and chemical handling regulations.
