Genyo Flow Controller We stock Lowara Genyo flow controller, an innovative solution for controlling and protecting various single phase pumps. Ideal for single use applications such as filling a tank or supplying a garden hose or washdown nozzle. |
Solar Powered Pumping Systems We are Proud to be Official UK distributors for Mono Solar Products. |
|
Washdown & Pressure Boosting Sets We offer a wide range of solutions for boosting water pressure, from domestic to commercial applications; including agricultural wash-down sets for parlors and dairy's. |
Variable Speed Pumps Variable Speed Pumps supply a constant pressure regardless of demand (within the capabilities of the pump). To achieve smoother operation, the pump will start off slow and speed up as the demand for flow increases. VSDs also reduce the pump wear extending their life expectancy and in many cases a VSD can reduce your electricity consumption. |

Ultra Violate Sterilization We supply ATG Willand and ITT Wedeco stainless steel UV systems. They have proven themselves in the field time and again, to be one of the best value for money and performance, with low running costs and ease of instillation and servicing. |
Sediment Filtration We offer a wide range of solutions for Sediment removal. |
Pressure Vessels, or Expansion Tanks are a necessary part of any booster set or pressurization system. They act as an intermediate buffer between pump and duty point, this prevents the pump(s) from running every time a tap is opened. This means the pump has fewer starts and overall wear is reduced, they also help prevent hammer from the pumps eventual start up and smooth out fluctuations in pressure.
How they work.
We use Lowara branded Zilmet Membrane Vessels, they have a steel shell (Mild and Stainless Versions available), with a Nitrile rubber bag inside. Pressurized air is held between the bag and shell, (air pressure is generally 3psi below the pump cut in pressure).
Water is pumped into the bag, the air compresses allowing the water to be stored under pressure, a sensor of some kind will turn off the pump at the desired pressure. When a tap is opened the stored water will leave the vessel, once sufficient water is expelled the pressure inside will drop and cut the pump in, filling the vessel again whilst meeting the systems demand.
The size of the vessel should be calculated based on the pump size and systems peek demand, bigger is not always better and conversely too small a vessel can be detrimental to the pumps and the vessels life. Regular maintenance is highly recommended, water pressure in the vessel would be determined by the pumps capability and the system requirements, air pressure should be set to 3 PSI below the cut in of the pump.
We stock a variety of pressure gauges and switches, we will also be happy to help size a pressure vessel or complete booster set for your system.
