A sump pump is a suction pump designed to remove groundwater from a structure and to displace it to the outside, away and as far from the structure as possible. The pump is typically installed inside of a pit, otherwise known as a sump pit or catch basin. When installed properly, the sump pit will collect groundwater at the lowest point within the structure. The sump pump rests on the bottom of the pit and will be in direct contact with ground water. The pump is then connected to a plumbing pipe, otherwise known as a discharge pipe. The discharge pipe is connected to the sump pump and installed in a manner that will guide the groundwater to a location outside and away from the structure.
When in operation, it is not uncommon for the best sump pump to be fully submerged by groundwater. When activated, the pump sucks the liquid from the pit and moves it (displaces it) to the connected discharge pipe. The pump stays in operation until a majority of the liquid is removed from the sump pit, however, does not remove all the liquid. Once the water is reduced to a manageable level within the pit, typically within 10-15 seconds, the best sump pump turns off and sits idle in anticipation for pit to fill with water once again. The rate at which the sump pit will fill with water, thus requiring another discharge depends on the volume of groundwater at that specific location.
The most common application of a best sump pump is to act as a water drainage device and is typically installed in residential basements and to prevent flooding. However, sump pumps can be installed anyplace else water drainage is required.
Types of Best Sump Pumps
SUBMERSIBLE SUMP pumps are electrically operated pumps which incorporate both the motor and pump into one unit. The entire assembly is designed to operate fully or partially “submerged” underwater. The pump is typically installed within a sump pit or catch basin. Most submersible pumps are designed to incorporate oil-cooled motor motor, which is sealed. This design protects the motor from moisture and dust, thus submersible pumps operate quieter and yield longer life expectancy than other types of best pumps. Due to these features, submersible sump pumps tend to be more costly than the other pump types listed.
SUBMERSIBLE SEWAGE pumps are similar in design and operation to a submersible sump pump. The main difference being that sewage pumps incorporate a heavy duty impeller, which enables a sewage pump to pump sewage waste water containing solids up to 2” in diameter.
PEDESTAL sump pumps are electrically operated pumps in which the motor is separate from the pump. The motor is elevated on a pedestal, above the water line, and the motor is not intended to get wet. The pump is typically installed within a sump pit or catch basin. Pedestal pumps are preferred in applications requiring more frequent pumping. Since the motor is exposed (not submerged), pedestal pumps tend to be noisier. Pedestal pumps tend to be less expensive than a submersible type sump pump.
WATER POWERED sump pumps are operated by water pressure generated by your buildings plumbing system. Water Powered pumps require no electricity to operate, however, they do not have the pumping capacity comparable to an electric pump. These pumps are typically installed as secondary pump, used to work in tandem with a primary pump or as a back-up sump pump during power loss.
FLOOR SUCKER UTILITY pumps are electrically operated pumps that incorporate both the motor and pump into one unit. Floor sucker pumps are similar in design to submersible sump pumps, however are designed to be operated in locations where a sump pit does not exist, ie, crawl spaces, basements cellars, roofs, etc… Where a pit is not present, it is ideal to remove as much of the water from the surface as possible. Floor sucker pumps remove water to within 1/8” of the floor surface. These pumps are great solutions for temporary or secondary pumping applications where additional pumping capacity is required or where water seepage is not commonly a problem.
