Water Pumps
There are a large number of different types of pump that are generally available to lift, move and pressurise private water supplies.
In summary, pumps are either installed into an underground water supply (Submersible Pumps) or they are located above ground where they draw water from a supply(Surface Pumps). SCL Water specialises in the supply of quality branded submersible and surface water pumps and is happy to offer advice and guidance on appropriate models.
Submersible Pumps
The abstraction of water from a purpose drilled borehole can vary significantly in depth. A domestic supply can be available from a depth of only a few metre however in most cases a minimum of 50 metres is necessary. For commercial and even more complex domestic boreholes, drilling to hundreds of metres is sometimes required to provide the quantity or quality of water. Accordingly the pumps needed to lift the water to the surface and then provide the correct pressure and flow vary enormously in shape , design and manufacture. SCL Water specialise in the supply of 3 " , 4" and 6" pumps powered by single or 3 phase electricity. The Grundfos 3" SQ/SQE range is a good example of a flexible , high quality solution
Well pumps
A large number of older properties have wells that were constructed many years ago. Some wells are being rediscovered as houses are extended and a small submersible pump can be used to lift the water for use in the garden as irrigation or even, after treatment, as part of the house supply. The DAB Divertron is an excellent example of a well pump as is the Grundfos SPO multistage pump.
Drainage pumps
These pumps tend to be submersible in design and specifically allow for the free passage of some solids. The degree of contaminant that can be pumped varies with the pump type but good examples can be found by clicking on the following link. DAB Drainage pumps
These systems are based on technology that senses water pressure and flow and adjusts the pump speed to maintain a constant supply at a pre set pressure.
A good example of the benefit of these systems is with domestic showers. When installed for a domestic property these systems ensure shower flow and pressure is unaffected by a tap being opened somewhere else in the house.
Booster systems
These surface mounted systems are designed to increase flow and pressure to preset levels without the need for large expansion vessels. Systems are typically installed where high pressure is required such as water supply for agricultural irrigation.
Water Regulation AB Air Break systems
The WATER SUPPLY (WATER FITTINGS) REGULATIONS 1999 mandates that a private water supply must not be allowed to cross contaminate with water supplied by a water authority unless an AB air break is installed.
Many customers believe that double check valves are acceptable. This is not so as they are mechanical valves, subject to breakdown and therefore unacceptable to the regulation authority.
To achieve this compliance, systems using booster pumps and tanks have been designed and an example of such a solution can be found on the Water regulation AB Air Break Web Page.
