Power

VACUOGRIP vacuum lifting devices are available in electric and pneumatic versions for optimal integration in the handling workstation.

PNEUMATIC

The vacuum is generated by a single-stage venturi equipped with a silencer.

■ Supply: non-lubricated air, filtered to 5 microns, according to standard ISO 8573-1:2010 [4:5:4].

■ Operating pressure: 6 to 7 bar.

■ Flow rate: 7.5 m3/h.

■ Air consumption: 3.2 l/s at 5 bar.

■ VGR version: pneumatic cylinder.

AVAILABLE OPTIONS:

■ PK3 version: The venturi is equipped with a vacuum control function to reduce energy consumption.

■ P3 version: The lifting device features a water trap for handling applications in wet environments.

ELECTRIC

The vacuum is generated by a dry rotary vane vacuum pump.

■ Flow rate: 8 m3/h.

■ Available voltages:

- Three-phase 230 V (2.35 A – 370 W)

- Three-phase 400 V (1.35 A – 370 W)

- Single-phase 230 V (3.9 A – 350 W)

■ VGR version: electric cylinder.

A lubricated rotary vane pump (three-phase 400 V voltage) + water trap version is available (version E3) for handling applications in wet environments, wherein the presence of water may damage the pump.

Number of suction cups

VACUOGRIP COVAL, horizontal vacuum lifting devices are available with 4, 6 or 8 suction cups.

VACUOGRIP vacuum lifting devices are available in versions equipped with 4, 6 and 8 suction cups in order to best match the dimensions and thickness of the sheet metal to be handled and ensure an optimal grip without any risk of deforming or damaging the loads.
