Page 3: Information On This Manual
The Teflon power cable is available in different lengths. Applications The Grundfos MP 1/Redi-Flo2 pump is designed for the purging and sampling of contaminated water. The maximum sand content of the water must not exceed 50 g/m . A larger sand content will reduce the life of the service parts and increase the risk of blocking of the pump. -
Page 4: Technical Specifications
The MP 1/Redi-Flo2 pump is not designed for continuous operation like for instance remedial pumping. Continuous operation may reduce the life of the pump. Technical specifications Marking: The MP 1/Redi-Flo2 sampling pump system is CE-marked. Submersible pump Grundfos MP 1/Redi-Flo2: Power input: 1.3 kW Voltage: 3 x 220 V, 400 Hz Maximum current: 5.5 A... -
Page 5: Safety
Safety Safety precautions During handling, operation, storage and transportation, the environmental regulations covering the handling of hazardous material must be observed. When the pump is taken out of operation, care must be taken to ensure that the pump contains no hazardous material that might be injurious to human health or to the environment. -
Page 6: Storage
Storage The pumping system should be stored in a clean and dry area. 4.2.1 MP 1/Redi-Flo2 pump Storage temperature: –20 °C to +50 °C. If the pump has to be stored after use, it must be cleaned thoroughly before storing. See section 9. Maintenance and service. -
Page 7: Checking Of Liquid In Motor
Checking of liquid in motor The level of the liquid in the motor should be checked before the pump is installed. 1. Place the pump and motor in a vertical position with the discharge port pointing downwards (i.e. the bottom of the motor is uppermost), and remove the filling screw. See fig. 4. 2. If the water stands up to the edge of the threaded hole, no filling is required. If not, fill demineralised water into the motor. -
Page 8: Converter
Converter Position of the converter Place the converter with cabinet (case) in such a way that water cannot enter into the cabinet. Do not close the cabinet during operation. The converter must be installed vertically to ensure free air circulation around the unit. See fig. 7. -
Page 9: Electrical Connection
Electrical connection Before starting work on the pump, make sure that the electricity supply has been switched off and that it cannot be accidentally switched on. Use the separate manual (M122746) on both converters for instructions on connecting the converter. Connection of the MP 1/Redi-Flo2 pump to the converter Connect the power (motor) cable from the pump with the power/motor cable of the converter. -
Page 10: Operation
After use After use, switch off the electricity supply to the converter before the motor cable is disconnected from the converter. Performance curves MP 1 / Redi-Flo2 pump Example When the static head is 66 m, discharge of the pump will be 0,34 l/s. -
Page 11: Maintenance And Service
Maintenance and service Maintenance If the pump is used alternately in several boreholes, it must be decontaminated before every sampling event or before possible storing. Clean the pump, cable, straining wire, etc. on the outside. Then dismantle the pump. Thoroughly clean the pump components before reassembling the pump. -
