The Grundfos MQ is a compact all-in-one pressure boosting unit that integrates pump, motor, diaphragm pressure tank, pressure and flow sensor, controller and non-return valve in a single self-priming package. Delivering flows up to 5 m3/h and heads up to 45 m, it starts and stops automatically on demand, with built-in dry-run protection, automatic reset and anti-cycling for quiet, low-maintenance operation. Self-priming from depths up to 8 m, the MQ installs on a small footprint with simple G1 pipe connections. Ideal for domestic water supply, pressure boosting from overhead and underground tanks, shallow wells, gardens, and light irrigation.
