DAB.S4 GG - 4" submersible pumps with water-filled motor
SUBMERSIBLE PUMPS
DAB.S4 GG ( S4 AMERIA)
Submersible centrifugal pumps for wells and boreholes larger than 4" diameter. The pumps are used for pumping water, for pressurizing and supplying water to the distribution systems of small and large buildings, civil and industrial, as well as for irrigation, washing and fire protection systems. Technopolymer impellers with stainless steel suction rings. Pump casing, shaft, motor coupling, integrated suction filter and stainless steel cable cover. Suction body, discharge body and hanging lugs in AISI 304 stainless steel. Removable integrated check valve in technopolymer or with stainless steel plate (depending on model). Technopolymer impellers designed to ensure a high level of efficiency in accordance with Directive 2009/125/EC (Eco design - ErP) with MEI ≥ 0.4 for the entire range. ACS certified, WRAS certified. The 4GG motor is a two-pole asynchronous motor, its parts in contact with water are made of AISI 304 stainless steel. The pressure block and bushings are cooled and lubricated with a mixture of water and glycol. The rotor is housed in plain radial bearings, the axial load is captured by a robust plain heel bearing.
