Compact, all-in-one unit, designed for home water supply systems The Grundfos MQ is a compact all-in-one water pressure boosting pump unit, designed for domestic water supply and other boosting or lift applications. The MQ is a compact and reliable, easy-to-install water pump, with many standard features. The MQ is a self-priming multistage centrifugal pump. It self-primes from a well depth of down to 25 feet within a maximum time of 5 minutes. The MQ pump is also ideal for pressure boosting from water storage tanks or from city water supply (maximum 45 psi inlet pressure). The MQ pump is built for long life, trouble-free operation. It is made from weatherproof, corrosion-resistant materials and can be placed outdoors.

EASY TO SELECT

The Grundfos MQ makes it easy to select the right pump. The MQ is an 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. With MQ it is literally a matter of connect the power and turn on the pump. Installation of an MQ pump is simple and can be done in a matter of minutes, which gives you more time to relax.

EASY TO INSTALL

The MQ pump is easy to install. The discharge connection can move up to 5° to fit existing pipework, and the compact design makes the pump easy to place even where space is limited. Easy to select Easy to install Easy to operate The Grundfos MQ features an easy-to-use control panel with indicator lights for indication of:

• pump on

• auto reset

• alarm (dry-running or overheating).

In the event of dry-run, the pump will stop and afterwards attempt to restart automatically. Restarting can also be done manually. If required, the auto reset function can be disabled as well.

General Description

The MQ is a compact water supply system consisting of a pump, motor, pressure tank and controller combined in an integral unit.

The pump starts automatically when water is consumed in the installation and stops when the consumption ceases. The MQ is a low-noise pump. The pump is self-priming and has a non-return valve incorporated in the suction port. The pump features a user-friendly control panel.

The pressure tank incorporated in the pump reduces the number of starts and stops in case of leakage in the installation.

The MQ pump has built-in over temperature and dry-running protection.
