Submersible centrifugal pumps for wells and boreholes with a diameter greater than 4“. The pumps are used for pumping water out, for pressurising and supplying water to the piping of small and large buildings, 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 strainer a kryt kabla z nerezovej ocele. Suction casing, discharge casing and lifting eyes are made of stainless steel AISI 304. Removable integrated check valve made of technopolymer or with a stainless steel plate (depending on the model). Technopolymer impellers designed to ensure a high level of efficiency in accordance with directive 2009/125 / ES (Eco design - ErP) s indexom MEI ≥ 0,4 across the whole range. They hold certification ACS, certifikat WRAS. Motor 4GG is a two-pole asynchronous motor, the parts in contact with water, su made of stainless steel AISI 304. The thrust block and bushings are cooled and lubricated by a water/glycol mixture. The rotor runs in radial sliding bearings, the axial load is absorbed by a robust sliding thrust bearing.

Frequently Asked Questions

Ako si vybrat spravny output/head pump? Musi pokryt tlakove straty vasho konkretneho okruhu (dlzka potrubia, pocet armatur) - pri nejasnostiach sa poradte s kurenarom, ktory vam pump vydimenzuje presne.
Musi installation vykonat odbornik? Osadenie pump do pripraveneho potrubia zvladne aj domaci majster, elektricke zapojenie a vyregulovanie systemu odporucame nechat skontrolovat odbornikom.
