Deep well pump with stainless steel pump housing and multi-stage pump impeller. Sand-resistant up to 50 g/m³ water. With built-in check valve, 23 m connection cable and 21 m lowering rope. The small external diameter of just 9.6 cm enables use in narrow drilled wells as little as 10 cm in diameter. For pumping water from great depths and sending it on under pressure. In addition, this AJ series model with 7 floating impellers is distinguished by its high flow rate.

A pump’s flow rate is mainly dependent on its static head. The term “static head” refers to the height difference between the water surface and the water outlet. The above table gives the capacity of the AJ 4 Plus 55/50 deep well pump at different static heads. At a static head of 20 metres, for example, the expected delivery rate for this pump is 2,100 litres per hour.
