Thanks to a refined hydraulic design, combined with innovative patented mechanical solutions, the new 4SR-S series of floating impeller pumps has been created, providing exceptional performance and efficiency, as well as a remarkable resistance to wear caused by the presence of sand in the water, 10 times higher than that found on other pumps on the world market!
The new 4SR-S pumps come standard with an innovative patented inductor that provides high priming capacity for operation in wells with mixed gas or air in the water.
They are recommended for pumping clean water. Due to their high efficiency and reliability, they are suitable for domestic, civil and industrial uses, water distribution in coupling with autoclaves, irrigation, washing plants, pressure raising, etc.
ADVANTAGES FOR THE USER: Reduced energy consumption and remarkable durability, even in the presence of sand (up to 200 g/m3), thanks to the innovative patented hydraulics.
reliability and ease of use, they represent the ideal solution for domestic use, particularly for water distribution coupled with autoclave tanks of small or medium size, as well as for the irrigation of gardens and vegetable gardens.Pedrollo 4srm4/6 s sumpmp pump - pd - 0.75hp - 230v
