Product detailed description

S4 16/12 M 4OL 4" submersible pump for boreholes and wells - 2,2KW -1x230V

Submersible centrifugal pumps pre wells a vrty, s priemerom larger ako 4". The pumps are used for pumping out water, pre tlakovanie
a supply water, do pipework small i large objektov, residential i industrial, furthermore pre irrigation, washing a fire-fighting
systems. Technopolymer impellers, so suction rings, z stainless steel. Casing pump, shaft, spojka s motorom, integrated suction filter a kryt cable z 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 z stainless steel (v depending od modelu). Technopolymer impellers designed k zaisteniu vysokej level efficiency v accordance so smernicou 2009/125/ES (Eco design - ErP) s indexom MEI ≥ 0,4 across the whole range. Have ACS certification and WRAS certification.

Motor 4OL je two-pole asynchronous motor, whose parts, which are v styku s water, are made z AISI 304 stainless steelL. Chladenie a mazanie ball bearings, ensures special food-grade kvapalina. Rewindable stator je housed v puzdre z AISI 304 stainless steelL, pripevnenom steel pins k hornej podpere motoru.
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.
