Submersible Pumps

A submersible pump is one that has a sealed motor, fitted in a pump body. The total assembly is immersed in the fluid that needs to be pumped. The main advantage of this type of pump is that it can offer a considerable amount of lifting power, as it does not rely on external air pressure.

A submersible pump has a system of mechanical seals that is used to prevent the fluid being pumped from entering the motor, resulting in a short circuit. A pump can either be attached to a pipe or a flexible hose.

Some of the types of submersible pumps are bladder pumps, bilge and ballast pumps, borehole pumps, booster pumps, and centrifugal pumps. Other examples are condensate pumps, dewatering pumps, fountain pumps, grinder pumps, micro pumps, sampling pumps, trash pumps, utility pumps, and well pumps. Some submersible pumps are manufactured for particular applications. These pumps are water submersible pumps, sewage submersible pumps, 12-volt submersible pumps, sand submersible pumps, irrigation submersible pumps, and solar submersible pumps. Solar submersible pumps have many uses and are suitable for slow and steady water transfer into a holding tank.

Submersible pumps are found in many appliances. Single stage pumps are utilized for drainage, sewage pumping, common industrial pumping, and slurry pumping. Multiple stage submersible pumps are normally used for water abstraction. These pumps can also be found in oil wells. Moreover, submersible pumps can be positioned directly in a pond and require comparatively little installation. These pumps are also relatively silent.

The four main specifications that should be considered while choosing a submersible pump are maximum expulsion flow, maximum discharge pressure, horsepower, and discharge size.

Earlier, the main drawback of submersible pumps was that its pump seal could rupture and release oil coolant into the water. However, newer pumps are magnet-driven, and no longer require a coolant. These magnet-driven pumps are more expensive, but they consume less electricity.

This is a nice blog, thank you for posting!

Earlier this week I toured the Franklin Electric factory in Wilburton, OK and it was very interesting.

The submersible motors Franklin makes are very quality. We learned about the kingsbury thrust bearing and that when the motor comes on it must reach 1800 RPM within 1 second and full speed within 3 to ensure a good life span of the motor.

You should come see my blog that is about submersible pumps and constant pressure pumps
