This pump is designed to increase pressure to enable a higher flow rate and improved dispense accuracy. It is ideal for applications where a low water level in a boiler causes an insufficient flow rate through traditional boiler dispense valves. Use of the pump allows for flexible positioning of dispense valves inside the machine, including up to 1 metre above the water level in the boiler. This is particularly useful in applications such as table top vending machines where space is limited. When a dispense valve bank is used with the pump, the bank can be fitted with a re-circulating bypass which allows water to be fed back into the boiler. This helps maintain a constant water temperature within the system. Varying the voltage supplied to the pump will change its speed and thus vary the flow rate output. The impeller is driven by a non-contact magnetic connection which avoids the use of additional seals preventing potential leak paths. The pumps body housing is suitable for use...
