Submersible Pumps SQE

SQE pumps are designed for pumping thin, clean, non-aggressive, and non-explosive liquids that do not contain mechanical or fibrous impurities. The main advantage of the SQE well pump series is the built-in electronic unit with a frequency converter that allows smooth speed regulation and ensures a soft start. They are made of AISI 304 stainless steel, which is suitable for contact with drinking water.

Applications

Pumps are suitable for continuous operation and are suitable for a wide range of operational applications

• Household water supply
• Use in small waterworks
• Irrigation
• Filling and emptying tanks
• Pressure boosting

Dry Run Protection

The pumps are protected against dry running. In case of insufficient water in the well, the pump will automatically shut off thanks to the control unit CU301, preventing overheating and motor winding damage. However, this function is only for emergency purposes. In the case of low well yield, the pump should be supplemented with external level monitoring.

High Efficiency of Pump and Motor

The electrohydraulic design ensures high efficiency for this pump, which is reflected in low electricity consumption, and thus in low operating costs. The motors are designed according to the permanent magnet principle (PM motor). This is the most modern type of synchronous electric motor, characterized by high efficiency and reliability across a wide performance range. The same type of motors is used, for example, in electric vehicles. Reliability and efficiency are also supported by auxiliary elements such as:

• Tungsten carbide or technical ceramic bearings
• Axial bearings as protection against upward axial pressure
• Longevity comparable to conventional motors
