Submersible pump SQE 5-70 1.85kW 1x230V hydrophore package 96524503

Compact submersible pump with constant pressure system

The device is a complete hydrophore set designed for supplying groundwater to single-family homes, small water supply installations, and irrigation systems. The construction, based on a 3-inch centrifugal pump with a diameter of 76 mm, allows installation in drilled holes starting from the pump's own diameter, significantly simplifying installation in narrow boreholes.

The key feature of this package is the built-in electronic system with a frequency converter, which ensures automatic maintenance of constant pressure in the installation regardless of current water consumption. The pump independently adjusts its rotational speed to changing demand, eliminating pressure fluctuations when multiple outlets are used simultaneously.

Motor with permanent magnets and protection system

The package uses a modern single-phase motor with a rated power of 1.85 kW powered by 230V, based on permanent magnet (PM motor) technology. This solution is used in electric vehicles, providing extremely high efficiency across a wide load range and significantly lower energy consumption compared to classic asynchronous motors.

The electronic system performs a soft-start function, eliminating the starting current peaks typical of submersible pumps and allowing operation even at reduced supply voltage. Integrated protections include dry-run, overload, overheating, and incorrect voltage protection - the CU301 controller will automatically switch off the pump in case of water shortage in the well.

Complete set for quick installation

The package is delivered as a ready-made set containing all necessary components: SQE pump with a 40-meter power cable, CU301 controller, stainless steel pressure transducer, 8-liter diaphragm tank, and a shut-off valve. This solution eliminates the need to select additional components - the installer receives everything in one package.

The maximum installation depth is 150 m, and the head reaches 73 m at a nominal flow rate of 5 m³/h (up to 100 m at a maximum flow rate of 7.4 m³/h). The pump is designed for continuous operation and can be installed vertically, horizontally, or in any intermediate position.

Materials and resistance to operating conditions

The pump body is made of AISI 304 (EN 1.4301) stainless steel, ensuring safe contact with drinking water according to current standards. The floating impellers made of GF30 nylon composite (ZYTEL) have their own ceramic bearings, ensuring quiet operation and wear resistance.

The device is designed to pump clean water at temperatures from 0°C to 35°C, without mechanical impurities or abrasive substances. The IP68 protection class allows direct contact with groundwater, and the factory-installed check valve prevents liquid return to the well hole after the pump is switched off.

The set meets the requirements of CE, PCBC, and RCM certificates, confirming its compliance with European safety and quality standards for water and sewage equipment.
