Product detailed description

S4 6/21 T 4OL submersible 4" borehole and well pump - 2,2kW - 3x400V

Submersible centrifugal pumps for studne and vrty, with priemerom larger as 4". Pumps are used for pumping-out water, for tlakovanie
and supply water, to rozvodov small i large objektov, residential i industrial, further for irrigation, washing and fire-fighting
systems. Technopolymer impellers, with suction rings, from stainless steel. Casing pump, shaft, spojka with motorom, integrated suction filter and cover cable from stainless steel. Sacie teleso, discharge teleso and hanging eyes are from stainless ocele AISI 304 from mikroliatiny. Removable integrated return valve from technopolymer or from stainless steel (in dependence from modelu). Technopolymer impellers designed to zaisteniu vysokej level efficiency in accordance with smernicou 2009/125/ES (Eco design - ErP) with indexom MEI ≥ 0,4 for whole range. Have certificate ACS, certificate WRAS.

Motor 4OL is two-pole asynchronous motor, whose parts, which are in styku with water, are made of stainless steel AISI 304L. Cooling and mazanie ball bearings, ensures special food-grade liquid. Rewindable stator is mounted in puzdre from stainless steel AISI 304L, pripevnenom steel pins to hornej podpere motor.
Equipped 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 can size the pump precisely for you.
• Must installation be carried out by a professional? Fitting the pump into a prepared pipe run can be handled by a handy homeowner; we recommend having the electrical connection and system balancing checked by a professional.
