Submissive pumps such as PV centrifugal, multi-stage, sectional. Designed for pumping water from large depths and with a large fluctuation in groundwater level, in which the content of mechanical impurities (sand, clay) does not exceed 50 mg/l and with particles of not more than 0.5 mm. Water temperature up to 25 ° C. The aggressiveness of water is allowed to pH = 6 ¸ 8.
PV type pumps are equipped with 380V immersion electric motors and a frequency of 50hz. < /span>
by agreement with the buyer, electric motors can be made with a different voltage and frequency. < /span>
