Choosing the right pump and hose
Choosing a pump (deep water pump, submersible pump, borehole pump, deep well pump) & hose
There are different types of pumps, which work on different principles. Suction pumps are used for water from dug wells, lakes or other water bodies. Submersible pumps and
ejector pumps are used for water from boreholes or for irrigation from dug wells and watercourses.
Once you have chosen the type of pump, it is important to choose the right model. Different models have different capacities, and therefore provide different amounts of water. But the amount of water you get is not only determined by the maximum capacity of the pump. The difference in level, the distance and the size of the pipe are also factors.
How much water do you need?
Start by making a note of all the places where you want running water. Washbasins and WCs, for example, require 6 liters/minute. Showers, sinks or small washing/dishwashing machines require 12 liters/minute
and bathtubs about 24 liters/minute.
Add up the liters and then choose the right pump for the water you need to use at the same time.
Where do you place the pump?
Submersible pumps, which push the water up, are lowered into the well.
Suction pumps are placed either indoors or in a pump house between the well and the house. The total suction height, expressed in meters of water column (mvp), must not exceed 7 meters.
The suction head is calculated by adding the difference in level and friction. If the suction head is more than 7 m, you must place the pump in a pump house somewhere between the well and the house.
(Frost-free if the pump is to remain in place all year round.)
Answer the questions and then look at the Suction Pump Guide. This will help you choose the right pump for your
particular circumstances. If you are unsure, you should consult us.
What level difference do you have?
The first step is to estimate the difference in level between the water surface and the pump location. The suction height is not affected by the fact that the
pipe runs over a hill or similar (siphoning effect).
What is the distance to the well?
Now you need to find out the length of the suction line, the distance between the well and the pump. The easiest way is to
increase the distance.
What dimension of the suction line?
Lastly, the choice of the right pipe size is extremely important. To make your work easier, we have compiled
all the information in a lathund showing the maximum pipe length in relation to level difference for different pipe dimensions and water velocities in polyethylene hose = Pem. Better to take a dimension too big than one too small.
Correct air pressure in a hydropressure tank
1. The pre-pressure (air pressure) in the hydro-pressure tank is loaded at the factory with 1.5 bar and should be checked 2-3 times a year.
2. The air pressure is easiest to measure with an air pressure tester for ordinary car tires, when the tank is emptied of water. The air valve is located under the black protective cap.
3. Disconnect the electrical power to the pump and open the nearest tap. The correct pressure in the empty hydropressure tank must always be 0.3 bar below the starting pressure.
Example: the pump starts at 2 bar. The correct pressure in the tank is then 1.7 bar.
Guide for suction pumps
The table shows different combinations that work well.
This concerns the dimension of the suction line, the level difference and
the line length.
Read this:
You need 60 liters/minute and the suction height is 3 meters. If you choose the 40 mm dimension, the pipe length must not be more than 42 meters. If you choose the 50 mm dimension instead, the line can be up to 180 meters.
