2GPe cVM e- drive - 1

Inverter controlled units with two vertical multi-stage pumps. TYPICAL APPLICATIONS GPE pressurisation units have the following applications: • Water supply or distribution networks, apartment blocks, schools, hotels, etc. • Generic industrial water supply • Irrigation for gardens, parks and sports facilities UNIT EQUIPMENT • Two CVM series pumps with 2-pole self-ventilating asynchronous motor, efficiency class IE2 for three-phase motors starting from 0.75 kW with E-drive series INVERTER • Control unit: pumps equipped with inverters for modulating control • INVERTER control of each pump with pressure transducer and electronic control display • Corrosion resistant materials for all components in contact with fluids • Galvanised steel base • Galvanised steel manifolds (AISI 304, AISI 316 available on request). The manifolds are dimensioned in relation to the total hydraulic output of the pressurisation system • Delivery side shut-off valve on each pump • Delivery side check valve • Protection against water supply failure as standard supply • Equipped for connection to delivery side accumulation tank Your Life, our Quality. Worldwide. INVERTER CONTROL UNIT E-drive is device for controlling and protecting pumping systems by varying the pump power voltage. E-drive can be connected to any commercially available pump, and is used to keep a given setting constant (pressure, flow rate, fluid temperature, etc.) as the operating conditions vary. This means that the pump runs only when needed, thus preventing energy wastage and increasing its service life. E-drive can also: • protect the motor from overloads and dry running • provide soft starts and stops to increase system life and reduce absorption peaks • provide information about current absorption and power voltage • register the hours of operation and trip alarms as required • run one or more pumps at constant speed (DOL: Direct On Line) • connect to other E-drives for combined operation • Voltage: - Version MT: - Power voltage: single-phase 230V - Output voltage (pump): three-phase 230V - Version TT: - Power voltage: three-phase 400V - Output voltage (pump): three-phase 400V • Mains power frequency: 50 - 60 Hz (+/- 2%) • Max. ambient operating temperature at nominal load: 40°C (104 °F) • Max. altitude at nominal load: 1000 m • Protection rating: IP55 (NEMA 4) • Digital outputs configurable as NO or NC: 1. motor run signal 2. alarm signal 3. pump command DOL 1 4. pump command DOL 2 • Analogue inputs (10 / 15 VDC): 1. 4-20 mA 2. 4-20 mA 3. 4-20 mA / 0 - 10 VDC (configurable) 4. 4-20 mA / 0 - 10 VDC (configurable) • 4 digital inputs, configurable NO or NC, for motor start/stop The contents of this publication must not be regarded as binding.
