Submersible pumps are designed to lift water to the surface from a great depth. These pumps are mainly used in wells that supply water to private homes, cottages, farmsteads, businesses and other places where water is needed.

Advantages of submersible water pumps:
• The pumps are cylindrical and compact, so they can supply water even from narrow wells.
• They can deliver water from great depths and over long distances, while maintaining sufficient pressure.
• Submersible pumps are strong and durable.

There are two types of submersible water pumps:
• Pumps with impellers made of technical polymer.
• Pumps with all stainless steel parts. The latter are highly resistant to abrasives. They can pump mineral water, water with a high content of sand, water with a low concentration of acids and oil impurities.

For wells with a high sand content, it is advisable to use submersible water pumps with floating impeller technology. Pumps of this design can successfully pump water with a sand content of up to 400 g/m.

Submersible pumps are lowered into wells using a steel cable
Pumps in their design must be equipped with a check valve so that water from the pipeline does not flow back into the well when the pump is not working. If the valve is not included in the design, it must be installed individually before the pump is lowered into the well.

Submersible water pumps can operate both vertically and horizontally. Pumps installed in a horizontal position are usually used to supply water from rivers, lakes or other natural reservoirs, as well as from fire fighting tanks.

Modern submersible pumps have frequency converters.
They regulate the speed of rotation of the electric motor of the submersible pump, which helps to maintain constant pressure in the pipeline regardless of the amount of water consumed. Submersible pumps also have dry running sensors that protect the pump from running out of water, as well as hydraulic accumulators (diaphragm tanks) that help stabilize the pumps.

The pumps are designed in such a way that the water is drawn at a higher level than the pump's electric motor. In this way, the pump motors are cooled. The pump's electric motor is cooled by water through the motor housing, so there is no direct contact between the water and the submersible pump's electric motor. The electric motor is completely sealed, and the torque is transmitted to the turbine of the submersible pump through a special connection. This allows the pump to run much longer. ¡Bienvenidos a Farmacia Mera Cerrato , tu farmacia de confianza en Parla!
