SiBoost Smart 1 HELIX VE5205-ES

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.

For fully automatic water distribution and pressure 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.

For pumping 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 attack 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 Helix VE series with an integrated air-cooled frequency converter
• High-efficiency pump hydraulics in conjunction with IE4-equivalent standard motors
• Disproportionately large frequency converter control range from 25 Hz to a maximum of 60 Hz (depending on 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

• 1 pump of the Helix VE 2 to Helix VE 52 series, with IE5-equivalent standard motor 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

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 expansion tank (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 LCD display to indicate status and actual pressure, button operation to configure pressure level and setpoint default 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.
