Product detailed description

S4 1/37 M KIT 4OL 4" submersible pump for boreholes and wells - 1,1kW - 1x230V

Submersible centrifugal pumps for wells and boreholes, larger than 4" diameter. The pumps are used for pumping water, for pressurizing
and supplying water, for the distribution of small and large objects, civil and industrial, as well as for irrigation, washing and fire-fighting
systems. Technopolymer impellers, with suction rings, stainless steel. Pump casing, shaft, motor coupling, integrated suction filter and stainless steel cable cover. Suction body, discharge body and hanging lugs in AISI 304 microalloyed 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 compliance with the 2009/125/EC Directive (Eco design - ErP) with MEI ≥ 0.4 for the entire range. ACS certified, WRAS certified.

The 4OL motor is a two-pole asynchronous motor whose parts in contact with water are made of AISI 304L stainless steel. Cooling and lubrication of the ball bearings is provided by a special food grade liquid. The rewindable stator is housed in an AISI 304L stainless steel housing, fixed by steel pins to the upper motor support.
Equipped with a carbon-ceramic mechanical seal.
