Hydro 2000

Product dataHydro 2000System configurationHydro 2000 consists of three main groups:• Hydro 2000 S• Hydro 2000 F• Hydro 2000 E.The main groups are divided into subgroups as shown in the table below.Description of pumpsMain groupSubgroupSizeNumberNumberof controlledpumpsMode of operationCommentsMS Full-size All Mains operation (start/stop)Hydro 2000 S(start/stop)MSHHalf-size 1 Mains operation (start/stop)Full-sizeAll otherpumpsMains operation (start/stop)MFFull-size1 1All otherpumpsSpeed control via frequency convertermounted in control cabinetMains operation (start/stop)Frequency-converter controlalternates among all pumps in thesystem.Hydro 2000 F(variable speed)MFHHalf-size 2 1Speed control via frequency convertermounted in control cabinetOnly one pump is frequency-converter-controlledat a time.Frequency-converter controlalternates between the two pumps.The uncontrolled pump is mainsoperated(start/stop).Full-sizeAll otherpumpsMains operation (start/stop)ME Full-size All AllSpeed control via frequencyconverter integrated in the motorAll pumps in operation run at thesame speed.Hydro 2000 E(variable speed)MEHHalf-size 2 2Full-sizeAll otherpumpsSpeed control via frequencyconverter integrated in the motorMains operation (start/stop)The two pumps run at the samespeed when both are in operation.MESFull-size 1 1Full-sizeAll otherpumpsSpeed control via frequencyconverter integrated in the motorMains operation (start/stop)Abbreviations:M: Control 2000 features a microprocessor for thecontrol of all functions.S: Some or all of the pumps in the system are mainsoperated(start/stop).F: Control 2000 features a frequency converter forthe control of some of the pumps in the system.E: Some or all of the pumps in the system are fittedwith MGE motors with integrated frequency converter.H: The system has one or two half-size pumps.(One half-size pump provides approximately thesame head as one full-size pump, but only approximatelyhalf the flow).7
