Compact pressure boosting system according to DIN 1988 and DIN EN 806, for indirect connection. Consisting of non self-priming, switched in parallel, horizontal stainless steel high-pressure multistage centrifugal pumps. Ready for connection to mains water supply via 260 litre Reg 4 approved fibreglass tank 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. The ISAR booster is fully compliant to The Water Supply (Water Fittings) Regulations 1999 (Regulation 4) and is suitable for safe drinking water applications
Special features/product benefits
- High operational reliability, thanks to system with one, two or three horizontal multistage CH1-L pumps with stainless steel hydraulics
- Easy installation and maintenance thanks to special, flexibly adjustable connections to manifolds
- Easy commissioning and operation with the Smart Controller
- Drinking water approval (reg 4) for pumps with components made of stainless steel that come into contact with the fluid
- 260 litre WRAS approved fibreglass tank with a removeable AB air gap lid, 3/4" inlet equilibrium ball valve, overflow and drain connections.
Equipment/function
- 2 CH1-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
- Low level float switch installed inside the tank.
- Pressure gauge, discharge side
- Diaphragm pressure vessel (8 l/PN 10)
- SCe comfort control device, maximum degree of control performance with symbol-based LCD display, simple navigation with clear menu and Green Button Technology for setting parameters for controlling the electronic pumps with frequency converters
- Ready for integration into building automation with the SCe switchgear via standard Modbus RTU
Operation / display
- LC display (backlit) for display of the operating data, controller parameters, operating statuses of the pumps, error messages and history memory
- Menu navigation with symbols and menu numbers
- LEDs for display of the system status (operation/fault)
- Factory-preset parameters for easy commissioning/start
- Setting of operating parameters and acknowledgement of fault messages using Green Button Technology
- Lockable main switch
- Operation with/without standby pump selectable by customer service
- Elapsed time indicator for each pump and for entire system
- Switching cycle counter for each pump and for entire system
- Fault memory for the last 16 faults
Monitoring
- Actual value of the system is output via a 0 – 10 volt analogue signal for external measurement/display applications, 10 volts correspond to the final sensor value
- 4 – 20 mA sensor signal (conductivity test of the sensor cable) for control variable actual value
- The pump mains power feed is protected via the circuit breaker
- Automatic switchover to standby pump in the event of an operating pump fault
- Monitoring of maximum and minimum system values with adjustable time delays and limits
- Zero-flow test for switching off the system when no water is being drawn off (adjustable parameters)
- Pipe filling function for filling empty pipes (initial filling of the consumer network)
- Protection against low water level via contact, e.g. for float switch or pressure switch
- Automatic shutdown of pumps if fault occurs or operation at preset emergency operation speed
Interfaces
- Potential-free contacts for SBM/SSM collective operation and collective fault signals
- Logic reversal can be applied to SBM and SSM
- Contacts for external on/off, low water and second setpoint
- External on/off via contact for deactivation of the system's automatic mode
