S4 8/15 T 4OL submersible 4" pump for boreholes and wells - 2.2kW - 3x230V

Product detailed description

S4 8/15 T 4OL submersible 4" pump for boreholes and wells - 2.2kW - 3x230V

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, for distribution in small and large buildings, both residential and industrial, and also for irrigation, washing and fire-fighting
systems. Technopolymer impellers with stainless-steel suction rings. Pump casing, shaft, motor coupling, integrated suction filter and cable guard made of stainless steel. Suction body, delivery body and lifting eyes are made of AISI 304 stainless steel micro-castings. Removable integrated check valve made of technopolymer or stainless steel (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.

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 sleeve, fixed to the upper motor bracket with steel pins.
Fitted with a carbon-ceramic mechanical seal.

Frequently asked questions

• How do I choose the right pump power/head? It must cover the pressure losses of your specific circuit (pipe length, number of fittings) - if unsure, consult a heating technician who will size the pump precisely for you.
• Does the installation have to be done by a professional? Fitting the pump into the prepared piping can be handled by a competent home handyman; we recommend having the electrical connection and system balancing checked by a professional.
