Product detailed description

S4 4/14 M 4GG submersible 4" pump for boreholes and wells - 1,1kW - 1x230V

Submersible centrifugal pumps for wells and boreholes with a diameter greater than 4". These pumps are used for pumping out water, for pressurising and supplying water to distribution systems in small and large buildings, both residential and industrial, as well as for irrigation, washing and fire-fighting systems. Technopolymer impellers with stainless steel suction rings. Pump casing, shaft, motor coupling, integrated suction strainer and cable guard made of stainless steel. Suction casing, discharge casing and lifting handles are made of stainless steel AISI 304. Removable integrated check valve made of technopolymer or with a stainless steel plate (depending on the model). Technopolymer impellers designed to ensure a high level of efficiency in accordance with Directive 2009/125/EC (Eco design - ErP) with an MEI index ≥ 0.4 across the whole range. Certified to ACS, certified to WRAS. Motor 4GG is a two-pole asynchronous motor; the parts in contact with water are made of stainless steel AISI 304. The thrust block and bushings are cooled and lubricated by a water-glycol mixture. The rotor runs on sliding radial bearings, while the axial load is taken up by a robust sliding thrust bearing.
