Design & Installation of Submersible Pump

SELECTION OF PUMP

Choose a pump appropriate for liquid handled.

• Liquid and Solid Size
• Example of foreign matte
• Application, Model

Be sure pump capacity is correct

Should too large a pump be selected, the following troubles can occur:

• The pump will be costly to operate
• Operation will not be economical because the pump is inefficient. Excess water will be discharged, resulting in motor over load.
• The pump may take in foreign matter.
• Pump wear will be excessive.

Accurately calculated piping loss plus additional 10% total head will assure correct pump operation.

Install pump in location facilitating maintenance

• When a building is constructed after pump installation, allow sufficient space for removal of pump.
• A manhole should be located above pump.
• Attach a mounting/demounting device to pump.

INSTALLATION AND PRECAUTIONS

It is recommended the following be checked immediately after the pump is delivered:

• Model, head, capacity, speed, output, voltage, frequency,etc. on the nameplate are as ordered.
• Possible damage incurred during shipment. Possible loose bolts and nuts.
• All accessories are included. Should there be any discrepencies, contact the dealer immediately.

In conclusion, selecting the right pump is crucial for efficient operation. Factors like liquid type, solid size, application, and model must be considered. Avoiding an oversized pump prevents costly operation, inefficiency, foreign matter intake, and excessive wear. Accurate calculations of piping loss and adding 10% to total head ensure proper pump performance. During installation, prioritize maintenance accessibility with ample space and necessary attachments. After delivery, check the pump’s specifications, inspect for damage, and verify accessory completeness. Promptly contact the dealer if any issues arise. Following these steps ensures optimal pump selection, installation, and maintenance.
