Installation

General Information

The Typical Installation shown is only a guide for selecting and installing system components. Contact your Graco distributor for assistance in planning a system to suit your needs. Always use Genuine Graco Parts and accessories. Be sure all accessories are adequately sized and pressure rated to meet the system’s requirements.

Reference letters in the text, for example (A), refer to the callouts in the ﬁgures.

Variations in color between the plastic components of this pump are normal. Color variation does not affect the performance of the pump.

Tighten Fasteners

Before mounting and using the pump for the ﬁrst time, check and retorque all external fasteners. Follow

Torque Instructions, page 16, or see the torque

tag on your pump. After the ﬁrst day of operation, retorque the fasteners.

Tips to Reduce Cavitation

c. Increase the size of the suction piping.

NOTE: Be sure the inlet ﬂuid pressure does not exceed 25 % of the outlet working pressure.

3. Reduce liquid velocity: Slow the cyclic rate of the pump.

one to cavitation.

Mount the Pump

Cavitation in an AODD pump is the formation and collapse of bubbles in the pumped liquid. Frequent or excessive cavitation can cause serious damage, including pitting and early wear of ﬂuid chambers, balls, and seats. It may result in reduced efﬁciency of the pump. Cavitation damage and reduced efﬁciency both result in increased operating costs.

Cavitation depends on the vapor pressure of the pumped liquid, the system suction pressure, and the velocity pressure. It can be reduced by changing any of these factors.

1. Reduce vapor pressure: Decrease the temperature of the pumped liquid.

2. Increase suction pressure:

a. Lower the installed position of the pump

relative to the liquid level in the supply.
