Grundfos MQ Jet Pump
|
The MQ is a compact water supply system consisting of
a pump, motor, pressure tank and controller all combined in one unit. The MQ starts when
it senses a minimum flow of 0.8 GPM or a pressure drop to 30
PSI (whichever occurs first). It then monitors the output to keep
the pump running until a very low flow rate is reached
(approximately 1/2 GPM). The MQ pump has a small built-in pressure tank to ensure that
water is readily available from the tap. When water is required
the pump automatically starts and no loss of pressure will be felt.

The pump starts automatically when the water is turned on and stops when the
flow stops. The MQ is a low-noise pump. The pump is self-priming and has a
built-in check valve. The pump is cooled by the pumped water which eliminates the need
for a noisy fan. Because the pump is self-cooling you don't need
to have free space around the pump for cooling purposes. And because the pump will keep
running down to very low flows, this overcomes problems of cycling.
The pressure tank incorporated in the pump reduces the
number of starts and stops in case of leakage.
Built-in dry-run protection
If the pump runs dry it automatically stops.
It will attempt to restart for a maximum of 24 hours until
water is available from the source. If more than 24 hours pass
without water it must be restarted manually. The auto reset
function can also be disabled.
Built-in thermal protection
If the pump overheats (dry running, overtemperature of liquid, overloaded motor, locked
rotor condition) it immediately stops. After a 30 minute
cooling-down period, the pump will automatically restart.
