Hydro 2000

Technical dataHydro 2000Dimensions and weightsThe previous pages state dimensions and weights forHydro 2000.Please note that the dimensions stated may vary by±10 mm and that all systems are supplied without vibrationdampers.All systems have the control cabinet mounted to theright of the pumps on a common base frame. However,there are certain exceptions:• Systems marked have the control cabinet centredon the base frame.• Systems marked are supplied with the controlcabinet mounted on a separate base frame.• Systems marked are supplied without a separatebase frame for the control cabinet.The control cabinet is mounted on its own base.The weights stated for these systems do not includethe control cabinet.ConstructionHydro 2000 is built up on a common stainless-steelbase frame (EN/DIN 1.4301). The pumps are fixed tothe base frame by means of bolts. The control cabinetis fixed to the base frame by means of a stainless-steelstand (EN/DIN 1.4301).A suction manifold of stainless steel (EN/DIN 1.4401 orEN/DIN 1.4571) is mounted on the suction side of thepumps. An isolating valve and a non-return valve aremounted between the suction manifold and the individualpumps. The non-return valve may be mountedon the discharge side on request.A discharge manifold of stainless steel (EN/DIN 1.4401or EN/DIN 1.4571) is mounted on the discharge side ofthe pumps. An isolating valve is mounted between thedischarge manifold and the individual pumps.The Control 2000 control cabinet is fitted with all necessarycomponents. All Hydro 2000 F control cabinets arefitted with a fan to remove surplus heat generated bythe frequency converter.Operating conditionsLiquid temperature: 0°C to +70°C.Ambient temperature: 0°C to +70°C.Operating pressure:The operating pressure depends on the pressure transmitter,but maximum is 16 bar. The maximum operatingpressure may also be limited by the diaphragm tankinstalled.InstallationA Hydro 2000 booster set must be installed in a wellventilated room to ensure sufficient cooling of pumpsand control cabinet.The booster set should be placed with a 1-metre clearancein front and on the two sides.Mechanical installationThe pipes connected to the booster set must be ofadequate size. To avoid resonance, expansion jointsshould be fitted in the suction and discharge pipes. Thepipes are to be connected to the manifolds of thebooster set. Either end can be used.It is advisable to fit pipe hangers both on the suctionand discharge sides.The booster set should be positioned on an even andsolid surface, e.g. a concrete floor or foundation. If thebooster set is not fitted with vibration dampers, it mustbe bolted to the floor or foundation.2Fig. 18 Mechanical installation1122TM00 7748 19961. Expansion joints.2.
