HGS-VT19-02-B 2-Stage Coaxial Venturi Vacuum Generator

The Vacuforce HGS-VT19-02-B is a compact, compressed-air-powered coaxial venturi vacuum generator from the HGS VT series. Its single replaceable coaxial venturi cartridge has a 2-stage ejector arrangement, identified by the -02 designation in the model number. The VT body has an overall height of 44.5 mm and is designed for installation near a single suction cup, which can be positioned directly beneath the generator when the compatible cup mount is used.

Published performance: Optimum supply 50.8 psi (3.5 bar); maximum vacuum 26.6 inHg (90 kPa vacuum); maximum vacuum flow 7.4 CFM (210 Nl/min); compressed-air consumption 4.3 CFM (123 Nl/min).

How the Coaxial Venturi Generator Works

Compressed air passes through the coaxial venturi cartridge, creating a vacuum at the generator port without a motor-driven vacuum pump. By positioning the generator close to the suction cup, the volume of vacuum plumbing can be reduced, which may improve evacuation response on repetitive pick-and-place equipment.

The coaxial cartridge contains the internal air passages used to produce vacuum. The body provides the mounting and connection arrangement, while the cartridge can be removed for servicing rather than replacing the entire generator assembly.

Performance values are from the supplied HGS performance table. CFM figures are volume-equivalent conversions of Nl/min at the same reference conditions; they are not independently measured SCFM ratings. Maximum vacuum and maximum vacuum flow are separate performance limits and should not be interpreted as occurring simultaneously.

Single Suction Cup, Inline Installation

The HGS VT generator can be mounted immediately above a single suction cup where the selected cup fitting is compatible. Keeping the vacuum source and cup in line reduces the need for long external vacuum hoses and provides a compact arrangement for robotic end-of-arm tools, transfer equipment and high-cycle handling machines.

Cartridge Maintenance and Replacement

  1. Switch off, isolate and depressurize the compressed-air supply.
  2. Remove the exhaust silencer to access the coaxial venturi cartridge.
  3. Withdraw the cartridge and install the correct replacement cartridge for the specific generator model.
  4. Check the seals, refit the silencer and verify vacuum operation before returning the equipment to service.

Using the replaceable cartridge design can simplify servicing and reduce the need to replace an otherwise serviceable mounting body. Use the applicable Vacuforce instructions for cartridge selection and reassembly.

Typical Applications

  • Single-suction-cup pick-and-place grippers
  • Compact robotic end-of-arm tooling
  • Decentralized vacuum generation at the point of use
  • Automated part transfer and handling systems

Cross-Reference Information

The existing Pneuforce listing references Piab Xi40-3 and 01.24.794 as a potential alternative. This is a selection reference, not a guarantee of interchangeability. Check dimensions, mounting, connections, vacuum-flow performance and operating requirements before substituting.

Selection note: The performance ratings above are based on the supplied HGS table. Confirm supply pressure, required vacuum flow, suction cup connection and cartridge configuration for the application. Maximum vacuum and maximum flow are separate performance limits.

Frequently Asked Questions

How does the HGS-VT19-02-B make vacuum?

It uses compressed air passing through a coaxial venturi cartridge to create a vacuum without an electric pump. The vacuum connection can be positioned close to the suction cup on the workpiece.

Can a suction cup be attached directly below the generator?

Yes, the HGS VT arrangement is intended for compact suction cup tooling. With the correct cup fitting, one suction cup can be positioned in line beneath the body, minimizing remote vacuum tubing.

What does -02 mean in the part number?

The -02 suffix identifies a 2-stage coaxial venturi cartridge configuration. It refers to stages within the cartridge, not 2 separate vacuum generators. Compare actual performance data when choosing between two- and three-stage versions.

How do I replace the coaxial venturi cartridge?

Isolate and depressurize the compressed-air supply, remove the silencer to access the cartridge, replace the cartridge with the correct approved size/configuration, then refit the silencer. Check seals and confirm operation before returning the machine to service.

Why mount a venturi close to the suction cup?

Reducing the distance between the generator and suction cup can reduce internal vacuum-line volume, improve vacuum response and simplify compact end-of-arm tooling.

What should I check when selecting a generator?

Compare required suction cup size, vacuum flow, leakage, evacuation time, available compressed-air supply, maximum vacuum rating and the space available for the 44.5 mm HGS VT body.

How much compressed air does the HGS-VT19-02-B consume?

The listed air consumption is 4.3 CFM (123 Nl/min) at the optimal supply pressure of 50.8 psi (3.5 bar). Use air consumption and expected duty cycle to estimate compressor demand. The maximum vacuum flow of 7.4 CFM (210 Nl/min) describes suction-side capacity, not compressed-air consumption.
