Control Panel

B - Sump Inlet Piping

Locate the inlet piping as far as possible from the pump suction.

Where possible, locate the inlet piping below the sump liquid surface, to prevent drawing air into the liquid in the sump.

If the liquid entering the sump contains significant amounts of air or vapor, use baffles to allow the air to reach the surface before reaching the pump suction connection.

C - Discharge Piping

Support the piping independently of the pump. The piping should line up naturally with the pump connection and not need to be forced into position.

Provide a discharge valve for isolation of the pump, should maintenance be required.

Provide a discharge check valve located between the pump discharge connection and the discharge isolation valve. A check valve is normally required to prevent back flow of the pumpage through the pump.

Provide a pressure gauge or at least a gauge connection on the discharge as close to the pump discharge connection as possible and before any valves.

D - The Pump Suction

Locate the pump in a position that will minimize turbulence at the suction connection.

Insure a sufficient clearance between the pump suction connection and sump floor to allow liquid to enter the pump.

If large solids are possible in the sump, utilize a suction strainer.

E - Mounting

Support the pump. Provide a rigid structure under the pump mounting plate to reduce vibration and noise.

Typically, vertically mounted pumps need to be level. Before installation, review the manufacturer's instruction manual to determine the degree of level required for the particular pump being used.

Note: There are many mounting configurations for vertical turbine pumps, including wet pit, dry pit, canned type, booster and other types of installations. Work with the manufacturer or local distributor to gain more practical information about your particular installation.
