Installation

Mountings

CAUTION

The pump exhaust air may contain contaminants. Ventilate to a remote area if the contaminants could affect your fluid supply. See Air Exhaust Ventilation on page 10.

1.Be sure the mounting surface can support the weight of the pump, hoses, and accessories, as well as the stress caused during operation.

2.For all mountings, be sure the pump is bolted directly to the mounting surface.

3.For ease of operation and service, mount the pump so the air valve cover (2), air inlet, and fluid inlet and outlet ports are easily accessible.

4.Rubber Foot Mounting Kit 236452 is available to reduce noise and vibration during operation.

Installation of Remote Pilot Air Lines

1.Refer to Parts Drawings. Connect air line to pump as in preceding steps.

2.Connect 1/4 in. O.D. tubing to push type connec- tors (14) on air motor of pump.

NOTE: by replacing the push type connectors, other sizes or types of fittings may be used. The new fittings will require 1/8 in. npt threads.

3.Connect remaining ends of tubes to external air signal, such as Graco’s Cycleflo (P/N 195264) or Cycleflo II (P/N195265) controllers.

NOTE: the air pressure at the connectors must be at least 30% of the air pressure to the air motor for the pump to operate.

Fluid Suction Line

DIf using a conductive (Acetal) pump, use conductive hoses (G). If using a non-conductive (polypropy- lene or PVDF) pump, ground the fluid system. See Grounding on page 5.

DThe pump fluid inlet (R) is a 1” raised face flange. See Flange Connections on page 8.

DIf the fluid inlet pressure to the pump is more than 25% of the outlet working pressure, the ball check valves will not close fast enough, resulting in ineffi- cient pump operation.

DAt inlet fluid pressures greater than 15 psi

(104 kPa, 1 bar), diaphragm life will be shortened.

DSee the Technical Data on page 32 for maximum suction lift (wet and dry).

Fluid Outlet Line

WARNING

A fluid drain valve (J) is required to relieve pres- sure in the hose if it is plugged. The drain valve reduces the risk of serious injury, including splash- ing in the eyes or on the skin, or contamination from hazardous fluids when relieving pressure. Install the valve close to the pump fluid outlet. See Fig. 2.

1.Use grounded fluid hoses (L). The pump fluid outlet (S) is a 1” raised face flange. Refer to Flange Connections on page 8.

2.Install a fluid drain valve (J) near the fluid outlet. See the WARNING above.

3.Install a shutoff valve (K) in the fluid outlet line.
