S4 12/24 T 4GG 4" submersible pump for boreholes and wells - 4,0kW - 3x230V DAB.S4 GG

Submersible centrifugal pumps for wells and boreholes greater than 4" in diameter. The pumps are used for pumping water , for pressurizing and supplying water to water distribution systems of small and large buildings, civil and industrial, as well as for irrigation, washing, and fire-fighting systems. Technopolymer impellers with stainless steel suction rings. Cladding pumps , shaft, motor coupling, integrated suctionfilter and stainless steel cable cover. body , the displacement body and the hinge lugs are AISI 304 stainless steel. Removable integrated check valve of technopolymer or with an anti-corrosion plate (depending on the model). Technopolymer impellers designed to ensure a high level of efficiency in accordance with the 2009/125/EC Directive (Eco design - ErP) with an MEI ≥ 0.4 for the entire range. ACS certified, WRAS certified. The 4GG motor is a two-pole asynchronouswater , they are made of AISI 304 stainless steel. The pressure block and bushings are cooled and lubricated with a mixture of water and glycol. The engine is housed in slippery radial bearing , the axial load is captured by a robust slippery heel bearing.
