Grundfos bus communication.

3 Stop function when operating at low flow (increases the efficiency when operating at low flow). Automatic cascade control of pumps. Automatic changeover between pumps in operation (ensures the same number of operating hours for all pumps). Manual operation (enables testing of individual pumps). Various setpoint influences: friction-loss compensation (pressure decreases with a decreasing flow) setpoint adjustment via external signals (temperature, time, level and flow). Various digital remote-control functions: start/stop of system reduced operation (limits the maximum number of pumps in operation) 2-point control of the setpoint (enables control of the setpoint by means of 2-point contact) 3-point control of the setpoint (enables control of the setpoint by means of 3-point contact) firefighting operation . Pump and system monitoring functions: minimum and maximum limits for the value measured pre-pressure measurement motor protection Grundfos bus communication.

4 Display, alarm and signal functions: 2 x 24 character LCD display indicator lights for operating and fault indication(green and red light-emitting diodes) potential-free changeover contacts for operating and fault signals.

The starting point when planning a booster set is supply area has its own consumption Grundfos Hydro 2000 booster set can be used fora wide range of applications.

5 A number of typical exam-ples are shown supplyAccess to the right quantity of clean water at the righttime is the key to a healthy term water supply covers: waterworks, pressure boosting in distribution circuits blocks of flats, schools, hotels, hospitals, of the water consumption in a typical water-works have revealed large differences in the daily waterconsumption pattern. Consumption is characterised by: sudden variations between min. and max. consump-tion variation taking place over long periods constant 2 Typical consumption pattern in waterworksIndustryIn a number of processes, water plays a vital part. Theindustrial consumption pattern varies with the type ofindustry. Many manufacturing processes consist of acycle requiring an absolute constant pressure evenwhere large and very quick flow variations areconcerned.

6 Among others, industrial pressure boosting and liquidtransfer comprise: the food industry the textile industry the petrochemical industry the pharmaceutical general, consumption is characterised by: large variations from minimum load to peak load sudden variations constant 3 Typical industrial consumption patternIrrigationIn order to maintain recreational areas used for specificpurposes, it may be necessary to term irrigation covers: gardening parks sports grounds, typical irrigation system could be used in connectionwith a golf course. When the irrigation system isstarted, consumption depends on the number of sprin-klers typical irrigation system is characterised by: irrigation zones variable, but known consumption system divided into pressure 4 Typical consumption pattern in irrigation applicationTM00 9197 1303 QhTM00 9200 1303TM00 9198 1303 QhQh6 Product dataHydro 2000 Type keyConstructionFig.

Pump changeover is automatic and depends on load, time and fault. The cut-out pressure (Hstop) can-not be set, but is calculated auto-matically. Maintains an almost constant pressure by cutting the half-size and full-size pumps in or out, as required. The half-size pump is always started first and cut out when a full-size pump is cut in. Pump changeover between the full-size pumps is automatic and depends on load, time and fault. The cut-out pressure (Hstop) can-not be set, but is calculated auto-matically. Maintains a constant pressure through continuously variableadjustment of the speed of one pump. The other pumps are cut in or out on mains operation, asrequired. The frequency-converter-con-trolled pump is always started first.
