SMC ZHP Vacuum Cup with Generator Review: Specs, Price and Applications
The SMC ZHP integrates a vacuum cup and a vacuum generator in one unit to save space. Its two-stage ejector increases suction flow by up to 50% and reduces air consumption by up to 30%.
Pads come in 63 mm and 80 mm diameters as grooved bellows or grooved flat types, in NBR, silicone, urethane or FKM, with nozzle diameters of 0.7, 1.0, 1.2 and 1.5 mm. Daisy-chain piping and lock-plate mounting simplify installation and maintenance.
Quick Verdict
A compact, efficient vacuum solution for cartons and panels. Generating vacuum at the cup shortens response time and cuts air use.

Design and Operating Principle
Placing the ejector at the cup eliminates vacuum hoses between generator and pad, which reduces the volume to evacuate and makes pick-up faster. Each cup has its own generator, so one leaking cup does not reduce vacuum for the others on the same gripper.
Two-stage ejectors use the exhaust of the first nozzle to drive a second stage, producing more suction flow for the same compressed air. That matters for porous cartons, where flow rather than ultimate vacuum level decides holding.
Bellows pads compensate height differences and uneven surfaces, while flat pads give stability on rigid, flat parts.
Integration and Selection
Choose pad diameter, type and material for the product surface and temperature, then select nozzle size to balance flow and air consumption. Use daisy-chain piping for multi-cup grippers.
Add vacuum switches if part confirmation is required.

Who Should Consider the SMC ZHP Vacuum Cup with Generator?
The ZHP suits packaging and logistics grippers needing efficient, compact vacuum at the cup.
Price and Availability
Price: Request a quote. SMC prices the ZHP by size, options and quantity, so the final figure depends on the exact configuration. Budget for the complete tooling package, including fingers or adapters, mounting, air or electrical connections and commissioning time, rather than the module alone.
