Grundfos CRFlex 5-6 - Surface Inline Pump - 13,000 Litres/HourSpecial Order
DescriptionThe CRFlex pump is available as a complete unit only, consisting of these parts:
- MGFlex motor
- CRN pump end.
The CRN is a vertical, centrifugal multi-stage pump. This inline (non-self-priming) pump is suitable for in-pipe systems and should be mounted on a foundation. It can lift up to 13,000 litres per hour @ 5 metres head, or up to 4,300 litres @ 55 metres head.
The pump is equipped with the MGF motor which can be run on both DC and AC. The motor electronics already include all the necessary motor protection functions; therefore, no extra motor protection device is needed. The Maximum Power Point Tracking (MPPT) software in the motor allows it to operate efficiently with solar panels. The motor has P1 1730W and maximum speed 3600 rounds per minute (RPM).
This new generation of CRFlex pumps has a DC voltage input of 30-300V DC - which means that they can operate with a single 24V solar panel (depending on your required head or output).
An external sensor can be connected in order to control the pump operation.
CRFlex pumps are applicable in thin, clean, non-aggressive, non-explosive liquids, not containing solid or long-fibred particles larger than sand grains. Maximum sand content: 20 ppm. A higher sand content will reduce the pump's life expectancy.
The price quoted is for the above items only. To calculate a full pump system for you (with solar panels, regulator, pipes, etc) we need to know:
- installation location
- maximum head required
- quantity of water required
- pipe and cable distances

The MGFlex motor was developed for optimal performance using solar power, for surface pump applications. In addition to solar panels, Grundfos solar surface pumps can be run from the grid or a generator. With variable speed operation and motor protection built in as standard, Grundfos solar surface pumps offer:
- Easy installation
- Virtually no maintenance
- Low cost and highly-efficient pumping
