Compact pressure-boosting system, for direct or indirect connection. Consisting of non-self-priming, vertically mounted, stainless steel high-pressure multistage centrifugal pumps in glanded versions, for which each pump is fitted with a frequency converter. Ready for connection with stainless steel pipework, mounted on a base frame, with all necessary measurement and adjustment equipment.
– Fully automatic water distribution and boosting in residential, office and administrative buildings, hotels, hospitals, department stores (for these purposes, systems with a standby pump must be provided in accordance with DIN 1988 and DIN EN 806) as well as in industrial systems.
Pumping of:
– Drinking water
– Process water
– Cooling water
– Firefighting water (apart from fire-fighting systems in accordance with DIN 14462 and with the approval of the local fire protection authorities) or other types of industrial water that do not corrode the materials either chemically or mechanically and do not contain abrasive or long-fibre constituents.
Special features/Product advantages
– Heavy-duty system featuring stainless steel high-pressure multistage centrifugal pumps from the Helix2.0-VE series with an integrated air-cooled frequency converter
– Highly efficient pump hydraulics in connection with IE5 EC motor drive. Disproportionately large frequency converter control range from 25 Hz to a maximum of 60 Hz (depending on the version)
– Integrated full motor protection via PTC
– Integrated dry-running detection with automatic cut-out in event of low water via performance characteristics of the motor control electronics
– Customised systems on request
Equipment/function
– One pump from the Helix2.0-VE 2 to Helix2.0-VE 52 series, with IE5 EC motor drive and continuous control mode with integrated frequency converter
– Base frame made of galvanised steel, with height-adjustable oscillation absorbers for insulation against structure-borne noise
– Parts that come in contact with the fluid are corrosion-resistant
– Stainless steel pipework
– Main switch available depending on version
On the discharge side:
– Shut-off valve
– Non-return valve
– Diaphragm pressure vessel 8 l, PN 16
– Pressure sensor 4 – 20 mA
– Pressure gauge
On the suction side:
– Pressure sensor 4 – 20 mA
– Pressure gauge
Installation on zinc-coated base frame with height-adjustable vibration absorbers, with diaphragm pressure vessel (volume 8 l) including throughflow fitting according to DIN 4807, integrated non-return valve, pressure sensors (4 – 20 mA) and pressure gauge for automatic control of the system via p = constant or p = variable. Delivery head setpoint continuously adjustable via a button on the frequency converter. Automatic zero-flow detection and deactivation. Integrated motor protection through electronic current monitoring.
With colour display to indicate status and actual pressure, button operation to configure pressure level and setpoint settings, and potential-free contacts for collective fault and collective run signal.
Wired and ready for connection as well as piped with shut-off valve, mounted on the discharge side on the base frame.
