Submersible centrifugal pumps pre wells a vrty s priemerom larger ako 4“. Pumps sa are used pre pumping out water, pre tlakovanie a supply water do pipework small i large objektov, residential i industrial, furthermore pre irrigation, washing i 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 AISI 304 stainless steel. Removable integrated non-return ventil z technopolymer or s nerezovou doskou (v depending od modelu). Technopolymer impellers designed k ensuring 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 4GG je two-pole asynchronous motor, jeho parts, which are v styku s water, are made z AISI 304 stainless steel. Pressure blok a puzdra are cooled a lubricated zmesou water a glykolu. Rotor je housed v plain radial bearings, axial load is absorbed by a robust plain thrust bearing.

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.
