The Grundfos MQ is a compact all-in-one pressure boosting system, designed for domestic water supply. This unit is ideal for pressure boosting from water storage tanks and/or from city supply (maximum 45 PSI inlet pressure).

In rural applications, such as drawing water from a well, lake or river, the MQ self primes from a depth of up to 25'.

All-in-one unit with two models to choose from. There is no need to worry about a separate pressure tank, pressure switch, electrical connections, fittings or any other separate items. The unit is made from weatherproof, corrosion resistant materials and can be placed outdoors.

Operating the pump is simple and easy.The actual settings are clearly indicated by light-diodes (LEDs) on the user-friendly control panel.

The MQ has a small built in pressure tank to ensure the water is readily available from the tap. When water is required, the pump automatically starts and no loss of pressure will be felt. It also feature a built in check valve.

Very quite to operate, this unit is specially designed for use in domestic applications where low noise is a major consideration. The pump is cooled by the pumped water, which eliminates the need for a noisy cooling fan. The control is calibrated to prevent the pump from continuously starting and stopping, when you have a dripping tap or minor leak in the system.

Protective features:
Built-in dry-run protection:
If the pumps starts dry, it will automatically stop. It will then attempt to restart every half hour for a maximum of 24 hours, until water is available from the source.

Automatic re-start:
If more than 24 hours pass without water, the pump must be re-started manually. The auto reset function can be disabled, if required

Built-in thermal protection.

Accessible priming plug.
