The SHERWIN-WILLIAMS PT2500 Sprayer has a 1/2 HP, 120 V, 60Hz AC, single phase, 1725 rpm motor (18). The motor is supplied with a three-wire power supply cord and a three-prong plug. The sprayer ON/ OFF switch is located on the box on the side of the motor. The motor's function is to drive the hydraulic pump. The motor runs continuously when it is turned on to keep the paint at the desired pressure.

Paint Pump

The paint pump (22) is immersed directly into a 5 gal- lon paint pail, so the pump is actually being pressure fed without the mess and trouble of pouring paint into a hopper.

Hydraulic Pump

The hydraulic pump (A) is located inside the hydraulic reservoir. The motor drives an eccentric bearing which pushes the piston in and out of the hydraulic pump.

The pump reciprocates the hydraulic fluid to operate the diaphragm.

Diaphragm

The diaphragm (21) separates the hydraulic and paint portions of the paint pump. Hydraulic oil causes the diaphragm to move up and down almost 30 times per second, no matter what pressure you are spraying at.

The paint pressure is regulated by turning the pressure control knob (4) clockwise to increase pressure and counterclockwise to decrease pressure.

Bypass Valve

The bypass valve (66) has two functions: (1) to assist in priming the paint pump during initial startup, and (2) to provide positive relief of paint pressure from the gun, hose and sprayer.

Paint Hose

One electrically conductive nylon paint hose (101) is supplied with the sprayer. This 7 m (25 ft.) hose has a 6 mm (1/4 in.) ID, 1/4 npsm(f) couplings and spring guards on both ends.

Spray Gun, Reverse-A-Clean (RAC) IV Tip Guard and Spray Tip

The spray gun (102) has a tough, lightweight plastic body. The gun has a trigger safety lever which pre- vents accidentally triggering the gun when the lever is set in the safe position. (See WARNINGS, page 4.)

The Reverse-A-Clean IV Tip Guard (B) uses high pres- sure fluid to unclog the spray tip without removing it from the gun. (See page 12.) The RAC IV includes a safety tip guard which helps reduce the risk of a fluid injection injury. A No. 413 spray tip for use with latex paint is also included.
