These guidelines are intended for those planning metering pump installations. They do not replace the instruction manual which should be read and understood before installation and commissioning.
Location
Site pump with protection from elements, preferably in a building. It should be on a level plinth or floor close to the supply tank with an adequate space for maintenance, especially dismantling of the pump head.
A containment bund should be provided with a capacity at least 110% of the volume of the tank. In extreme climatic conditions a hood or cover should be considered for the pump and associated pipework and fittings. Mounting the pump above the containment ood level will minimize damage in the event of a chemical leak.
Pipework General
Suction and discharge pipework should be short and direct Avoid use of short elbow fittings, unnecessary bends and loops Pipework must not impose strain on pump connections Always flush pipework to remove dirt etc. before initial start-up All pipework must be of adequate size, long runs may require larger bores
Suction
For accurate results, variations in suction conditions should be kept to a minimum. Where possible use solution vessels having a larger diameter and minimum change in contents level. Termination should always be 100-200mm (4-8’’) from the bottom to prevent
