VARIABLE SPEED BOOSTER SETS Wide range of 1, 2, 3 and 4 pump variable speed booster sets with individual transducers for each pump giving a very robust operating system. APPLICATIONS • Water supply to domestic dwelling and ofce buildings, hotels, shopping centers, factories, and greenhouses. • Water supply for agricultural use (irrigation systems). • Water supply to systems requiring constant pressure. GTKS MULTISTAGE INTRODUCTION Lowara booster sets have been designed to be both compact and cost effective. Both the TKS and Hydrovar range are built to exacting standards and as such are suitable...

INSTALLATION AND SERVICE Each set comes fully packaged complete with isolating valves, non return valves (Anti-vibration feet), and pressures sensors. Small sets are provided with screwed manifolds whilst all other sets are provided with anged manifolds. Pressure vessels are normally supplied separate from the base to keep the pump set size to a minimum for ease of shipping and manoeuvrability, however vessels can be integrated into the pump set when required. All pumps can easily be removed for servicing. PUMPS Lowara have been manufacturing a large range of high quality end suction and vertical...

SELECTING A SET The rst thing to do when selecting a set is to determine the volume of water required and the pressure it must produce. CALCULATING THE FLOW RATE • The volume of water called water requirement depends on the type of users, e.g. homes, ofces, schools, as well as their number. The theoretical requirement is the total volume of water required by all the users. In actual fact, since it is very unlikely that there should be a simultaneous demand by all the users, the real requirement is lower than the theoretic one. CALCULATING THE HEAD • The pressure required depends on the type of...

ASSESSMENT OF PROBABLE DEMAND The method adopted is based on loading unit values as detailed in the Plumbing Engineering Design Guide published by the Institute of Plumbing. When designing a hot or cold water supply system an assessment must be made to obtain the maximum probable simultaneous demand. Depending on the type of services being provided it rarely occurs for all the appliances to be used at the same time therefore the design usually allows for a peak usage which is less than the maximum. Probable demand will depend on, the type of building and its use, type of appliances installed...

ASSESSING HEAD REQUIREMENT The head required in a boosted cold water system consists of three components, static head, residual pressure and system friction losses. The values of these three components are added together to give the total required head at the system ow rate. Static head (He): This is the difference between the break tank low water line and the highest discharge point in the building. If the height of the build is not known, then 2.83.0 metres per oor can be used to assess the building height. Residual pressure (Hr): This is the pressure required at the highest outlet device,...
