Grundfos 25 Sqf-6 Sqflex Solar Pump,25Gpm Nominal

To avoid risk of voiding the warranty for the Flex Series pumps, use of a Grundfos control box is highly recommended.

Grundfos
SQFlex Pumps

The complete SQFlex pump range consists of 7 different pump sizes: 4 centrifugal and 3 helical rotor pumps. All pumps are fitted with the same size motor which, together with the new sizing tools, makes system sizing simple.

SQFlex - Features

SQFlex pumps have build-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

SQFlex - Applications
WATER, WHEREVER, WHATEVER
With the advances in pump technology over recent years, areas that would previously have been considered uninhabitable or not supportive of life have become viable and attractive. With the new SQFlex system, Grundfos can consolidate these areas and pioneer further into new territories: Consolidating by upgrading older unreliable pump technology, and pioneering by providing more stable and low-maintenance pumping solutions in even more remote areas.

Potential SQ Flex applications include:

• Live stock watering
• Remote Homes
• National/State Parks
• Irrigation
• Remote Camps
• In locations where power is scarce and water is a necessity.

	1 HELICAL ROTOR PUMP Based on original pumping principles, the helical rotor pump uses a few, simple components for effective pumping in high head and low flow conditions.	CENTRIFUGAL PUMP (4") Technology based on 30 years' experience enables high flow in shallow water conditions. Stainless steel components give high wear resistance.
	2 PUMP CASING Stainless steel for long pump life.
	3 BEARINGS Powerful carbon/ceramic bearing system ensures extreme reliability.
	4 MOTOR Only one motor for the entire pump range with built-in unique features. A newly developed segmented stator provides high efficiency.
	5 POWER TRANSMISSION The unique Grundfos micro frequency converter ensures power transmission to the motor.
	6 SYSTEM EFFICIENCY Maximum Power Point Tracking (MPPT) means even and high system efficiency regardless of power source.
	7 COMMUNICATION Two-way communication between interface box and pump eliminates the needs for additional wires.
	8 ANY VOLTAGE A wide voltage range enables the motor to operate at any voltage between 30V and 300V DC or 90-240V AC, which makes installation and sizing especially easy.

SQFlex - Energy Sources

In the middle of nowhere, the only things you can depend upon are air and daylight. The SQFlex pump is fully operational from only one or, for greater peace-of-mind, a combination of these energy sources. SQFlex Solar and Wind systems are reliable, low-mainteance and cost-effective. In addition, the systems are sustainable and totally environmentally sound.

SQ Flex Grundfos centrifugal or helical rotor quality system for about the cost of a diaphragm pump. The Grundfos SQ Flex pumping system can also be powered by a wind generator if you have the right site. The Whisper H-80 Waterpumper is the required generator. Features:

• Up to 390 foot head applications
• 30-300 VDC, or 90-240 VAC single-phase AC input
• Permanent magnet high efficiency motor
• Overload protection
• Over temperature protection
• Dry running protection
• Maximum Power Point Tracking to optimize pump operation according to DC Power available
• Power line communication with the CU200 (optional) to display operational conditions
