Submersible pumps operate with partial or full immersion in the pumped medium. The pumped liquid cools the pump.
Well pumps. They are used to lift water from wells and shallow wells and special tanks and natural reservoirs. These pumps are completed an adjustable float switch for autonomous operation.
Downhole pumps. They are used to lift water from artesian wells located at a depth of more than 30m. These pumps provide high water pressure.
Drainage pumps. They are used for pumping water with large mechanical impurities.
Fecal pumps. They are used to pump out sewage.
Surface pumps are installed on land and can lift water from a shallow well, river, or lake. For the surface pump to raise water from a considerable depth (up to 25 m), it is equipped with an external ejector. The ejector increases the pressure of the liquid in the pipeline.
Centrifugal pumps. They are among the most demanded.
Execution options:
Working principle: using impeller blades, a centrifugal force is created, under the action of which water is pushed out under pressure.
Vortex pumps. They are used for pumping clean water.
Vortex pumps are installed indoors or in places protected from atmospheric influences.
Vibrating (membrane) pumps. They have a working vessel divided by a flexible membrane.
On one side of the membrane, there is a cavity filled with water. On the other hand, there is a mechanism that sets the membrane in motion.
The vibrator bends the membrane, a vacuum is created, and water is sucked into the pump cavity. Then the vibrator bends the membrane in the opposite direction, creating an excess working pressure, as a result of which the water is pushed into the water supply system.
Vibrating (electromagnetic) pumps.
Circulation pumps. They are used mainly for water circulation in heating systems, hot water supply, and floor heating. They have low power consumption, small dimensions, and operate almost silently.
Cantilever pumps. These pumps circulate the liquid in heating, air conditioning, ventilation, fire extinguishing systems and are used to increase pressure in water supply systems. The working body of the cantilever pump is a centrifugal wheel. The cantilever pumps include centrifugal single-stage cast iron pumps with a one-way liquid supply to the impeller.
The hand pump for water is designed to lift water from a source with a depth of 7-30 m.
The design of the pump depends on the operating conditions and the depth of the well.
There are several types:
Water pumps are highly mobile and operate autonomously, which allows them to be used in places where conventional pumps are not possible.
The heart of a pump is made up of two elements: the pump and the motor that drives it. Water pumps are predominantly equipped with centrifugal pumps.
Water pumps can be:
