Installation
DISCHARGE LIHE
1. Use a pulsation dampener or a desurger in the discharge line. It should be placed in the line as near the fluid cylinder as possible and ahead of any bend in the line.
2. Do not reduce the size of the discharge line below that of the pump outlet until the line has passed through the desurger, and is away from the pump approximately 20 feet {6m).
3. Any bend in the discharge line should be made with a long radius 45" ell. Do not use a bend directly adjacent to the fluid cylinder, particularly a 90" bEnd-4- A pressure relief valve should be installed in the discharge line. The relief valve should be set to operate at a pressure no greater than 2506 above the maximum rated pressure for the plunger size being used. lt should be installed in the line ahead of any valve and be piped so that any flow ls returned to the supply tank rather than the suction line. This will prevent possible damage to the suction line and suction dampener.
5. A by-pass line should be installed to permit the pump to be started without load. This allows oil to circulate and reach all parts in the power end before they are loaded.
