Compact pressure-boosting system in accordance with DIN 1988 and DIN EN 806, for direct or indirect connection. Consisting of non-self-priming, switched in parallel, vertical stainless steel high-pressure multistage centrifugal pumps. Ready for connection with stainless steel pipework, mounted on a base frame, including control device with all necessary measurement and adjustment equipment.
For fully automatic water supply and pressure boosting in residential, commercial and public buildings, hotels, hospitals, department stores and for industrial systems.
For pumping drinking water, process water, cooling water or other service water, which does not affect the materials used, neither chemically nor mechanically, and does not contain any abrasive or long-fibre constituents.
Special features/product benefits
– High operational reliability, thanks to system with one, two or three vertical multistage CV1-L pumps with stainless steel hydraulics
– Easy installation and maintenance thanks to special, flexibly adjustable connections to manifolds
– Easy commissioning and operation with the Easy Controller
– Drinking water approval (ACS and UBA List) for pumps with components made of stainless steel that come into contact with the fluid
Equipment/function
– 2 or 3 CV1-L pumps per system
– Components that come in contact with the fluid are corrosion-resistant
– Electrogalvanized base frame with height-adjustable vibration absorbers for insulation against structure-borne noise
– Stop valve on every pump on the suction and discharge sides
– Non-return valve, pressure side
– Pressure sensor, on the discharge side
– Pressure gauge optional, on the suction side
– Pressure gauge, discharge side
– Diaphragm pressure vessel (8 l/PN 10)
– Low-water cut-out switchgear, optional
– EC-control with IP54 plastic housing, consisting of an internal power supply unit, microprocessor, analogue and digital input and output modules
Operation / display
– Fully electronic Easy Controller with internal power supply unit, microprocessor, analogue and digital inputs and outputs for control and linking of speed-controlled single pumps
– Factory-preset parameters for easy commissioning/start
– Configuration of setpoint, operating parameters and acknowledgement of fault signals using red-button technology
– LC display (backlit) for display of the operating data, controller parameters, operating statuses of the pumps, actual pressure, error messages and history log
– LEDs for display of the system status (operation/fault/low water/overpressure)
– Lockable main switch
– Menu navigation with symbols
– Locking the parameter settings
– Operation selectable with / without standby pump
– Elapsed time indicator for each pump
– Elapsed time indicator for entire system
– Mains on/off counter for each system
