Submersible Pumps

Siegert Water Wells, Inc. has been in business since 1933

Submersible Pumps or Electric Submersible Pump (ESP) is a pump that may be submerged in a liquid or fluid. The motor is hermetically sealed and is encapsulated in the body of the pump casing. This ensures that the motor will remain functional even when it is submerged in liquid, usually water, storm water or sewage. Submersible dry pit pumps can be installed without being submerged, unlike wet well submersible pump installations dry well stations are not flooded with water or sewage. They are typically built below ground level, the dry well pumping station is most vulnerable to flooding, thus the use of a submersible pump to protect the motor from liquids. The biggest problem becomes how to keep the submersible pump motor cooled, the popular way is with a cooling jacket. Other names for submersible pumps may include sump pump or sewage pump.

Submersible pumps vary in size and capacity depending on the conditions, required GPM discharge, head/lift condition, as well as friction losses from distance of piping, valves and fittings. Proper sizing is most important. Some submersible pumps are automatic incorporating a float switch built into the pump itself, larger systems usually relay on a control panel and float switches to operate one or more pumps.

Pump Types
Submersible pumps consist of both sump pumps and sewage pumps. The submersible pump can be used in a number of other applications as well such as well pumps, fountain pumps.

How Sump Pumps work
Submersible pumps work by protecting their motors from the liquid being pumped. Usually, the motors are placed in water tight compartment filled with air or oil. Most motors used in submersible pumps are electric.

Submersible pumps are typically used for effluent and sewage for basements, loading docks, low lying areas where water collects, sewage drains that are below sewer from restrooms in homes and businesses.

Submersible pumps feature a submerged motor (either air-filled or oil-filled motors) and different impellers which are designed to accommodate solids of various sizes.

Types of Fluids
Submersible pumps are designed to handle water and thinner liquids. They can pump liquids with or without solids when proper impeller type is chosen.

Submersible pumps eliminate vertical column shafts, bearings, housings and other wearable parts, they are more compact and reduce installation costs. They are shorter and usually have a smaller footprint. Cost savings for conversions from Vertical Column pumps to submersible.
