Installation

Fluid Suction Line

DScrew the suction line (L) into the pump inlet (M) snugly. Use a compatible liquid thread sealant on connections to prevent air from getting into the fluid line.

DDo not pressure feed this pump.

DSee the Technical Data on page 24 for maximum suction lift.

DUse an agitator (U) to prevent fluid from settling out. Part No. 245081 Agitator Kit (accessory) is available.

Fluid Outlet Line

WARNING

A fluid drain valve (J) is required in your system to relieve pressure in the hose if it is plugged. See Fig. 2. The drain valve reduces the risk of serious injury, including splashing in the eyes or on the skin, or contamination from hazardous fluids when relieving pressure. Install the valve close to the pump fluid outlet. To use the valve as a circulation valve, connect a tube (K) between the valve and pail.

CAUTION

Some systems may require installation of a pressure relief valve at the pump outlet to prevent overpres- surization and rupture of the pump or hose.

Thermal expansion of fluid in the outlet line can cause overpressurization. This can occur when using long fluid lines exposed to sunlight or ambient heat, or when pumping from a cool to a warm area (for example, from an underground tank).

Overpressurization can also occur if the pump is being used to feed fluid to a piston pump, and the intake valve of the piston pump does not close, causing fluid to back up in the outlet line.

DUse electrically conductive fluid hoses (P). Screw the fluid fitting into the pump outlet (N) snugly.

DInstall a fluid regulator (H) at the pump fluid outlet to control fluid pressure, if desired. See Air Line, step 1a, for another method of controlling pressure.

DInstall a fluid drain valve (J) near the fluid outlet. See the WARNING at left.

Flush the Pump Before First Use

The pump was tested in lightweight oil. If the oil could contaminate the fluid you are pumping, flush the pump thoroughly with a compatible solvent. Follow the steps under Starting and Adjusting the Pump on page 11.
