Product detailed description

S4 2/52 T 4GG 4" submersible pump for boreholes and wells - 3,0kW - 3x400V

Submersible centrifugal pumps for wells and boreholes larger than 4" diameter. The pumps are used for pumping water, pressurizing and supplying water to water distribution systems of small and large buildings, civil and industrial, as well as for irrigation, washing and fire protection systems. Technopolymer impellers with stainless steel suction rings. Pump casing, shaft, motor coupling, integrated suction filter and stainless steel cable cover. Suction casing, discharge casing and hanging lugs in AISI 304 stainless steel. Removable integrated check valve in technopolymer or stainless steel (depending on model) Technopolymer impellers designed to ensure a high level of efficiency in accordance with Directive 2009/125/EC (Eco design - ErP) with an MEI >0.4 for the entire range. ACS certified, WRAS certified.

The 4GG motor is a two-pole asynchronous motor whose parts in contact with water are made of AISI 304 stainless steel. The pressure side and bushings are cooled and lubricated with a mixture of water and glycol The rotor is housed in plain radial bearings and the axial load is captured by a robust plain heel bearing
