This high-powered AJ 3 Plus series model is distinguished by an extra-high static head. The maintenance-free capacitor motor with thermal overload protection is water-cooled and suitable for non-stop operation. This deep well pump has a stainless steel pump housing and multi-stage impeller, and is sand-resistant at a content of up to 50 g/m³ of water. The small external diameter of just 7.4 cm enables use in narrow drilled wells as little as 8 cm in diameter. Designed for pumping water from great depths and sending it on under high pressure.
Package includes:
– 21 m lowering rope
Flow rate and static head:
50.0 m – 850 l/h
40.0 m – 1,600 l/h
30.0 m – 2,100 l/h
20.0 m – 2,400 l/h
10.0 m – 2,700 l/h
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 3 Plus 50/55 deep well pump at different static heads. At a static head of 20 metres, for example, the expected delivery rate for this pump is 2,400 litres per hour.
