Vacuum Pad
Vacuum Pad Metal detectable type (-S3 spec.)
Made of Silicone rubber containing metal detectable additive which is ideal for food processing line.
-
No copper-based metallic material is used in flow paths
-
HNBR or FKM is used for the seal rubber material. *Some products are only compatible in the flow path.
Advantages
In case a fragment of the vacuum cup is mixed in, metal detectors will respond.
Iron powder type and SUS powder type are available.
SUS-powder type is the industy's first, of which wear debris is resisti to rust.
*There are possibilities that the metal detector does not detect a fragment of SUS-powder type pads depending on its settings or a type of food. Conduct a test to ensure it works.
Response ratio rate of iron powder type is more than twice compared with others' (In-house testing)
Vacuum pad lips with/without rib types are available.
Two types of durometer hardness, 30°and 51°are available.
Durometer hardness can be identified by the color.
Lip part and bellows part sticking problem is mitigated. (Comparion with existing models）
Includes sticking-prevention bumps.
Identification code for the cup material is typed on the top.
Pad surface treatment for minimizing suction marks on workpieces is available as an option!
Large Suction Flow type with dramatically improved suction power is available.

Detailed Safety Instructions
Caution
1.Conduct adsorption tests on the actual equipment when making a selection.
2.Metal detectable vacuum pad is made of silicone which contains metallic powder.
3.Note that the durability of the product will be reduced by lifting heavy workpieces.
4.There may be color unevenness on a pad, which does not affect the performance.
Frequently Asked Questions for Vacuum Pad Series
The highest operative temperature limit depends on the pad material. For Urethane rubber's highest operative limit is 60℃, nitrile rubber's 110℃, and fluorine rubber's 230℃. (For the other rubber materials' highest limits, please refer to our catalogue.)
The above highest operative temperature limit is for only instant use. When the product is used under the highest operative temperature limit for a certain length of time, careful attentions are necessary.
Request of spring force change will be treated as a special order request in PISCO. Please contact your nearest sales office.
*) Please note that we cannot always meet a request of changing the spring force.
Yes, they are.
For the standard holder types such as VPC and VPD, the key way machined on the shaft gets fit with the rotation-lock thread so that it prevents the shaft rotation.
For small sized pad holders such as VPMC and VPMD, shaft itself is hexagonally machined which prevents rotation.
It is possible to minimize suction force decline of a vacuum pad by installing a fall prevention valve on multiple vacuum pads even when there are un-sucking pads.
The fall prevention valve, however, does not completely shut down the air circuit and it sucks a little amount of air. Depending on the number of un-sucking pads, required vacuum for the air circuit may not be achieved.
Besides, in case of sucking one work peace by multiple Vacuum Pads, even when the fall prevention valve can reduce vacuum decline, there is still a possibility that the work peace loose the balance so that the sucking Vacuum Pads may be released.
Please refer to the following "pad inner diameter" of the pad rubber to be attached.
| Pad size | Pad inner diameter |
|---|---|
|
φ1mm |
φ0.5mm |
|
φ2mm |
φ0.6mm |
|
φ3mm |
φ0.8mm |
|
φ4mm |
φ1.2mm |
|
No pad rubber (pad holder only) |
φ1.6mm |
*) Adsorbable up to this pad diameter
The inner diameter of the pad holder itself of the Air Pincette is φ1.6 mm, but since the pad diameter φ1 to 4 mm mentioned above has a smaller pad inner diameter than that, it is possible to adsorb workpieces of φ1.6 mm or less as shown in the above figure.
The pad inner diameter of the pad size φ6, 8 mm is larger than the pad inner diameter of the holder, so it is suitable for φ1.6 mm or more.
It is a dimensional calculation to the last, and may differ depending on the workpiece to be adsorbed. Ultimately, we ask you to judge the actual machine.
There are two ways of measuring pressure, absolute pressure and gauge pressure.
Absolute pressure
Absolute pressure is zero-referenced against a perfect vacuum.
It is commonly used to measure flow rate.
When indicated, "abs" is inserted following the unit, for example 10 kPa abs.
Gauge pressure
Gauge pressure is zero-referenced against ambient air pressure.
It indicate how much pressure per １cm2 is against the ambient air pressure. It is commonly used for indication of manometer. When the pressure is over the ambient air pressure, it is called "positive pressure" and when it is under the ambient air pressure, it is called "negative pressure."
