Product detailed description

S4 8/27 T 4OL 4" submersible pump for boreholes and wells - 4,0kW - 3x230V

Submersible centrifugal pumps for wells and boreholes, with a diameter greater than 4". The pumps are used for pumping out water,  for pressurising and supplying water, to the distribution systems of small and large buildings, residential and industrial, furthermore pre irrigation,  washing a 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. Sacie teleso, discharge  teleso a lifting eyes are z stainless ocele AISI 304 z mikroliatiny. Removable integrated non-return ventil z  technopolymer or made of stainless steel (depending on the model). Technopolymer impellers designed k zaisteniu  vysokej level efficiency in accordance with the directive 2009/125/ES (Eco design - ErP) with an MEI index ≥ 0,4 across the whole range. Have  certificate ACS, certificate WRAS.

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

Frequently Asked Questions

• How do I choose the right pump output/head? It must cover the pressure losses of your specific circuit (pipe length, number of fittings) - if in doubt, consult a heating engineer who will size the pump precisely for you.
• Must the installation be carried out by a professional? Fitting the pump into prepared pipework can be handled even by a skilled DIYer, but we recommend having the electrical connection and system balancing checked by a professional.
