SQE pumps are designed for pumping clean, non-aggressive and non-explosive liquids, not containing solid particles or fibres. Equipped with a high efficiency motor with permanent magnets, they also incorporate a frequency inverter to ensure constant pressure operation. For variable speed operation SQE pumps require a CU300 or CU301, pressure transducer and a pressure tank. CU301 is easy to use with Up/Down arrows to control pressure. CU300 is advanced control requiring a GrundfosGO. SQE pumps are suitable for both continuous and intermittent operation for a variety of applications: domestic water supply, small waterworks, irrigation, tank applications or pressure boosting.

Pumps with high efficiency motor and integrated protection against :

• Dry running (automatic restart every 5 minutes)
• Overvoltage and undervoltage, cuts out below 150 Volt and above 315 Volt (up to 6000 Volt)
• Overtemperature
• Overload
