Submersible Pump Selections
Document Number: 247
A Submersible Pump is a pump that can operate when totally submersed in the liquid being pumped. Since submersible pumps are submersed in a liquid and/or in direct vicinity to liquids, the electrical components/connections are UL Listed for water applications as well as being waterproof to prevent electrical shock. In addition to electrical components being waterproof, the manufacturers still suggest use of a GFCI (Ground Fault Circuit Interrupter) to be installed in the branch circuit that supplies electricity to a submersible pump.
Submersible pump motor housings are completely sealed and require little or no service when installed and used per manufacturers instructions.
Motors of submersible pumps are designed for continuous-duty use, meaning that they are engineered and constructed in a manner to operate for long duration. Pump motor housings of submersible pumps are normally filled with dielectric oil for motor heat transfer as well as for lubricating of the internal moving parts of the motor. Cooling of the motor is also assisted from the liquid that the submersible pump is in contact when in use.
Submersible pumps are offered in a variety of models that are constructed specifically for pumping of water and wastewater in commercial and/or industrial settings. Some examples of typical uses include crawl space and basement sump drainage, seepage cleanup, wash area discharge, flooded rooms, water discharge from construction sites, dewatering waters that collect on flat roofs, and recirculating water systems (eg. fountains).
The most common categories of submersible pumps for use in special applications are frequently marketed/referred to as Portable Utility Sump Pumps, Sump/Sewage Pumps, Continuous Duty Sump Pumps, High Temperature Effluent Pumps, Dewatering/Sludge Pumps, and Waterfall/Stream Pumps. Performance specifications like horsepower, liquid discharge rates/volumes, material construction and portability are the key elements that differentiate these categories of submersible pumps from one another. Choosing a submersible pump that fits a specific application should be done with the help of the distributor and/or manufacturer who will indicate what and how their specific sump pump is primarily been designed for.

| A. |
|
LSS offers a variety of submersible pump offerings of different brands and performance specifications. Some of these pump offering choices are:
- Continuous duty stainless steel pumps for standard sump draining, overflow tank draining, and waste water draining.
- Dewatering and Effluent pumps for light to medium duty wastewater transfer demands that require movement of liquids that may contain solids.
- Sewage Ejector Pumps for effluent waste water removal, wastewater and sewage handling where liquids that may contain solids need to be moved from a collection area to sewer or septic lines or to drainage areas.
- High Temperature Effluent pumps that have the specifications to handle liquids containing solids at temperatures up to 200 degrees F.
- Portable Sump and Sewage Pumps that are continuous-duty that are designed for draining flooded excavation sites, basements, or swimming pools.
- Waterfall & Stream Pumps that are ideal for use in decorative indoor and/or outdoor applications requiring continuous water flow.
- Small/Miniature Submersible Pumps that are commonly used for saw coolant systems, and/or machine tool coolants, or for use where continuous flow of liquid is needed.
- Sludge Pumps for use in removing water containing sand, solids, leaves, and/or other debris.
