Domestic waterworks with submersible pump 3" STM 20 with frequency converter - RTS

Product detailed description

Domestic waterworks with 3" STM 20 submersible pump with VESSER frequency converter for setting the desired pressure in the system. Application: regulation to a constant system pressure via frequency converter pumping of domestic and drinking water from deep and narrow boreholes and wells pumping of tanks irrigation and sprinkling setting up of water supply systems for houses, cottages, social and agricultural buildings water supply automatic pressure stations suitable for domestic and professional use suitable for continuous operation The 3" STM 20 submersible pump has increased resistance to sand or other abrasive substances that may be present in the water. The submersible pump with the RTS designation stands for Resistance To Sand. The 3" STM 20 submersible pump with floating impellers is also designed for new, fresh boreholes, wells, tanks, reservoirs and sumps. This pump is suitable for pressure boosting when installed in distribution pipes, furthermore for domestic or industrial use, irrigation or water spraying. The hydraulic part of the 3" STM 20 pump is separated from the motor (the pump is not built as a monoblock - in case of failure, the pump can be easily dismantled. Any repairs (which are carried out by us) do not have to be too expensive and are especially quick, which is a great advantage in the event of a breakdown. The pump is equipped with a thermal protection fuse. The 3" STM 20 submersible pump is also suitable for small and medium-sized fire stations or as part of a domestic waterworks with a submersible pump. Equipment and advantages: 3" STM 20 submersible pump with VESSER frequency converter electronic motor speed control via built-in frequency converter soft smooth pump start-up protection against dry running and low level protection against overvoltage and undervoltage overload protection overheating protection stainless steel construction guarantees long service life and corrosion protection encapsulated single-phase motor floating impellers housed in their own bearing suitable for pumping from depths of more than 8 m; 50m submersion below the surface suitable for domestic and industrial applications easy assembly and disassembly The 3" STM 20 submersible domestic water pump with VESSER frequency converter includes: Pump 3" STM 20 Frequency converter VESSER IQ-E 2,2kW Pressure vessel 8l with fitting Nipple reduced 5/4" x 1" Check valve 1" Transition piece with external thread 32x1" 2x
