Product detailed description

S4 12/44 T 4OL Submersible 4" Borehole and Well Pump - 7.5kW- 3x400V

Submersible centrifugal pumps for wells and boreholes, larger than 4" diameter. The pumps are used for pumping Water or aqua (chemical formula H2O, by the traditional name hydrous oxide, more recent system name oxane[1]) is a chemical compound of hydrogen and oxygen. Technopolymer impellers, with suction rings, stainless steel. Sheathingpumps, shaft, motor coupling, integrated suctionFilter can be: sorting principle, selection principle a device or substance that/that doesn't let something through (but lets others through) in chemistry and engineering: Suctionbody may be: in geometry: a closed and confined area of space in algebra: a circle in which the nonzero elements also form a group with respect to the other operation,a solid algebra in physics: a solid(physics) Removable integrated checkValve: A technical device in piping, see valve (fitting) A component in machines with different functions: cylinder charge change control, see valve (reciprocating internal combustion engine) 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 4OL motor is a two-poleasynchronous asynchronousstator 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.
