Grundfos SQ Flex

The Grundfos SQ Flex is a versatile submersible pump system designed for off-grid water supply applications, particularly in remote or challenging environments. With its ability to run on both solar and AC power sources, the SQ Flex offers a wide range of applications. Here are some examples:

1. Remote Water Supply: The SQ Flex is ideal for providing water supply in remote areas where access to grid power is limited or unavailable. It can be used to extract water from boreholes, wells, or other water sources, ensuring a reliable water supply for domestic use, livestock watering, or irrigation.

2. Off-Grid Living: The SQ Flex is well-suited for off-grid residential settings, such as cabins, cottages, or remote homes. It can provide a self-sufficient water supply solution, utilizing solar power when available and seamlessly switching to AC power when needed.

3. Agriculture and Irrigation: This pump system can be used in agricultural settings for irrigation purposes. It can efficiently deliver water from boreholes or wells to sprinkler systems, drip irrigation setups, or other agricultural irrigation methods, supporting crop growth and water conservation.

4. Livestock Watering: The SQ Flex is suitable for providing water to livestock in remote areas or off-grid locations. It can reliably pump water from boreholes or wells to watering troughs or other livestock watering systems, ensuring proper hydration for animals.

5. Community Water Supply: The SQ Flex can be utilized to supply water to small communities or villages. It offers a sustainable water solution, especially in areas where centralized water supply systems are not available or unreliable.

6. Environmental Projects: The SQ Flex is applicable in environmental conservation projects that require a reliable water supply. It can be used to support habitat restoration, wildlife watering stations, or ecological monitoring projects in remote or off-grid locations.

7. Emergency Water Supply: This pump system can serve as an emergency water supply during power outages or natural disasters. It ensures immediate access to water from boreholes or wells, providing a critical resource for drinking, sanitation, and emergency response.

8. Remote Monitoring Stations: The SQ Flex can be used in remote monitoring stations or research facilities that require a dependable water supply. It provides water for scientific studies, data collection, or environmental monitoring applications in off-grid or challenging environments.

The Grundfos SQ Flex, with its adaptability to solar and AC power sources, offers a reliable and versatile solution for various off-grid water supply applications. Whether it's remote water supply, off-grid living, agricultural irrigation, or community projects, this pump system provides efficient water delivery, sustainability, and flexibility in challenging environments.

PUMP
A range of four models of helical rotor pumps for high heads and low flows (suitable for 3” boreholes) and six models of centrifugal pumps for low heads and high flows (suitable for 4” boreholes) are offered with stainless steel used extensively in construction for both pump designs. Pump model selection is determined by the duty requirement.

MOTOR
Grundfos MSF 3 high-efficiency permanent magnet motor is specified with all pump types. The motors can be powered by either DC or AC voltage within the range of 30-300V DC and 1X90-240V, 50/60Hz AC. An integral control module uses MPPT technology that continuously optimizes output frequency to maximize system efficiency and protects against over and under voltage (except lightning), electrical overload, and over temperature. Effective dry running protection is provided by a sensor in the motor cable.

CONTROL UNITS
A variety of switch boxes are available for the various installation options including IO50 for a manual solar system, IO101 for solar/generator systems, and IO102 for a wind system. In addition, a CU200 (1400W) or CIU903 (2500W) control units are offered which provides for high-level switch control together with system monitoring and alarm indication.

SOLAR MODULES
SQ Flex systems are recommended to be powered by crystalline photovoltaic modules connected in arrays to provide the power selected. Arrays should be connected to produce at least 40V input voltage with a higher voltage of around 100V recommended for maximum efficiency operation.

ACCESSORIES
A complete range of accessories including connecting cabling and fittings, drop cable, and module support structures are available to provide all necessary components for a complete site installation.
