An extra-high-powered model specifically designed for household use: for watering gardens and lawns, cleaning patios and footpaths, automatic water supply and running watering systems.
Deep well pump with 8-stage pump impeller.
High-quality stainless steel pump housing
Patented hydraulic system: sand-resistant up to 50 grams of sand per cubic metre of water; protection from damage due to dry running.
With built-in check valve and lowering rope.
For very narrow drilled wells 10 cm or more in diameter.
For pumping water from great depths and sending it on under high pressure.
Flow rate and static head:
45 m – 36 l/min – 2.15 m³/h
40 m – 49 l/min – 2.95 m³/h
35 m – 59 l/min – 3.55 m³/h
30 m – 66 l/min – 3.95 m³/h
25 m – 69 l/min – 4.15 m³/h
20 m – 78 l/min – 4.65 m³/h
15 m – 83 l/min – 4.95 m³/h
10 m – 88 l/min – 5.30 m³/h
5 m – 94 l/min – 5.65 m³/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 4 Plus 100/57 deep well pump at different static heads. At a static head of 20 metres, for example, the expected delivery rate for this pump is 78 litres per hour or 4.65 cubic metres per hour.
Maximum number of sprinklers:
Just like garden pumps, deep well pumps are ideal for running watering systems such as sprinklers. This model is suitable for connection to a maximum of 6 sprinklers. This number is based on the following standard values:
Water flow at sprinkler: approx. 600 l/h
Water pressure at sprinkler: approx. 2 bar
