ISAR MODH1-3CH1-L-405/EC

Compact pressure boosting system according to DIN 1988 and DIN EN 806, for direct or indirect connection. Consisting of non self-priming, switched in parallel, horizontal 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 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 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

• 1, 2 or 3 CH1-L pumps per system

• Components that come in contact with the fluid are corrosion-resistant

• Electrogalvanised base frame with height-adjustable vibration absorbers for insulation against structure-borne noise

• Stop valve on every pump on the suction and pressure sides

• Non-return valve, on the pressure side

• Pressure sensor, on the discharge side

• Manometer optional, on the suction side

• Manometer, on the 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 controlling and linking speed-controlled single pumps

• Factory-preset parameters for easy commissioning/start

• Adjustment of the setpoint, operating parameters and acknowledgement of the fault messages thanks to Green Button Technology

• LCD display (backlit) for displaying the operating data, the controller parameters, the operating status of the pump, the actual pressure, the error messages and the history log

• LEDs for displaying the system status (operation/faults/water shortage/overpressure)

• Lockable main switch
