Multi -stage centrifugal pumps with increased sand resistance. 3.5 SDM pumps as one of the few on the market have constructions resistant to compact sand in water. The effect of sand resistance was achieved thanks to the use of "floating" rotors and the selection of consumption resistant materials (brass compressing connector and a brass suction body).
The best and most economical solution for single -family houses and farms agricultural. Thanks to the small diameter and the factory connection of the 20 m long cable (capacitor Built in the engine engine) a simple pump in assembly. Very high efficiency compared to the pump diameter, allow wider use of pumps. Max. Pump diameter 90 mm. Power supply 230V ~ / 50 Hz.
3.5 "SCR1,8-50-0.5 is a deep, displacement pump, screw. Power supply 230V ~ / 50Hz.
