Design Specifications
Renewable energy-based water supply system: The Grundfos solar surface pump is the simplest system utilizing solar energy for water transfer. This system offers the following benefits:
Technical Support
Grundfos teams of skilled service technicians provide different services:
Replacement Components
Spare parts are supplied by Grundfos. Grundfos provides 24/7 worldwide delivery through the MyGrundfos platform
Lifecycle
The lifetime is typically 10 - 25 years. End-of-life information for the MGFlex motor is online
Manufacturer Specified Performance Parameters
Specified performance targets: Temperature Range [°F]: -4 to +250 If the pump is used for liquids with a viscosity higher than that of water, this will reduce the heat and increase the power consumption. Specified chart see below, with - Typical deviation: + / - 15 %. - The measurements have been made at a water temperature of +70 °F (+20 °C).
Vetted Performance Status
The solar surface pump respects the Tolerances to ISO 9906 test. and the motors used for the measurements are standard Grundfos MG motors.
Safety
Built-in protection for under and overvoltage and system overload. No additional protection is therefore required. Care should be taken when handling the motor due to the weight.
Complementary Technical Systems
Three models are available, all powered by the same 1250W motor providing a selection of head and flow outputs depending on the application. Grundfos has developed a PC-based sizing tool enabling the sizing of the system. The sizing tool is integrated into Grundfos WinCAPS and covers solar-powered systems. The following three parameters must be known for the sizing of the optimum system:
