GRUNDFOS SQFLEX
SQFlex pumps
The complete SQFlex pump range consists of 11 different pump sizes: 5 helical rotor pumps for medium to high heads and low to medium flows, and 6 centrifugal pumps for shallow heads and high flows. It is available in two different stainless steel material variants: type AISI 304 as standard and type AISI 316 for slightly aggressive water. The pump is fitted with a highefficiency motor for DC and AC voltage. This makes pump sizing and selection extremely easy
SQFlex pumps have built-in protection features that protect the pump itself and in many cases the well. Among these features are:
- Protection against dry-running, overloading and overheating
- Automatic restart when water returns to the well or when the motor temperature returns to the safety range
- Continuous load condition and voltage monitoring
- A wide voltage range enables the motor to operate at any voltage between 30V – 300V DC or 90-240V AC, which makes installation and sizing especially easy.
- Centrifugal pump (4”) Technology based on 30 years’ experience enables high flow in shallow water conditions. Stainless steel components give high wear resistance.
Backup systems
Natural energy rarely runs low, but if it ever does, both the SQFlex Solar and SQFlex Wind systems can temporarily use a gas or diesel-driven generator or batteries. intelligent control units make changing between power supplies very easy. Stay flexible with SQFlex SQFlex
