Masterprime

Self-Priming Centrifugal pump with closed or semi closed impeller suited to dewatering and transfer applications on flooded suction and suction lift installations.

Economical, reliable and convenient

Self-priming pumps are often the best solution if your water source is beneath the level of your pump. For example, using sub artesian water to provide make up water to a cooling tower or drawing sea water from the harbour for recirculation through a heat exchanger. Varying tide levels can mean standard centrifugal pump to lose their prime causing major performance and maintenance issues with your HVAC plant. The problems of having partial block foot valves is also a compelling reason for installing a self-priming type pump.

WE CAN HELP YOU CHOOSE THE RIGHT MASTERPRIME PUMPS FOR YOUR PROJECT

The design of the Masterprime volute casing, ensures the residual volume inside the casing allows the pump to prime from a dry start. This eliminates the requirement for a foot valve to be installed as a means of keeping the suction line full of liquid. Masterprime can be supplied in exotic materials for use in landfill and sea water applications where transfer of corrosive liquid is required.

To select the correct self-priming pump for your application you need to obtain critical information about your system. On the suction side you need to measure the vertical height from the water level to the pump centreline. If the source is tidal, then this distance must be the low tide measurement. On your discharge side the static head plus a list of all the devices installed in the pipework system. If this is a completely new installation, Masterflow can work though the selection process with you and assist in determining pipe diameters, pump location and determine the best method of control. If your enquiry is for a pump replacement, then a site measure may be necessary to ensure pipe modification is minimised.

Masterprime pumps are available in a range in sizes including 80mm,100mm,125mm,150mm and 200mm discharge.

Frequently asked Questions

In most cases there is no need to install a foot valve because the pump already has an integral flap valve which acts as a non-return valve. This prevents liquid from draining to the water source and ensures there is a residual liquid volume to enable the pump to prime on the next start-up.

On a centrifugal pump you can operate on a closed discharge but only for relative short periods of time. Operating the pump indefinity will eventually cause the trapped liquid to heat up and get very hot causing damage to the pump.
