Grundfos MQ Jet Pumps
The Grundfos 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.
