Our suction cup valves are a group of products that serve to save energy in various applications at the suction cup.
It depends on the weight of the product that should be lifted and how many suction cups that can be used for the object. Calculate the weight to be lifted per suction cup and then take the weight multiplied with the gravity force (g = 9,81) and you have the lifting force needed in Newton (N).
Our recommendation is to start at the application listing to find the products we recommend to different applications. If you have questions please do not hesitate to contact our partners to find the optimum solution.
Please see our storage guidelines:
All suction cups not in contact with an object (open) will draw in a lot of air and demand a larger pump than actually necessary. By using different valves, such as piSAVE® sense, in the suction cups, the suction cups will be normally closed until they come in contact with the handled object. Only the cups needed in the specific lifting cycle will be open and flow air. Please see the video piSAVE® sense.
DURAFLEX® is a patented material specially developed to feature the elasticity of rubber and the wear resistance of polyurethane. The DURAFLEX® material is mark-free.
When the pumps are on, the vacuum ejector pump actually uses more energy than the mechanical, however most vacuum applications are intermittent- suction and release- and the ejector pump can follow that cycle and be switched off and on easily along with the cycle which in total gives a much lower energy consumption compared to the mechanical pump that is on all the time.
Piab offers a warranty to distributors, integrators and users of Piab products worldwide as per the following definitions:
The multistage COAX® vacuum ejector is designed so the maximum vacuum level can be adjusted by the compressed air feed pressure. By using a piSAVE® optimize, you can set the specific vacuum level needed and the piSAVE® optimize will adjust the feed pressure to the pump accordingly. You will never use more compressed air than needed in the application. Please also try the piSAVE® optimize calculator to see the actual energy saving by doing this.
The easiest way is to use the selection guide in the pump section. MICRO, MINI and MIDI describe size and capacity where MICRO is smallest and MIDI the largest. Each are available in a few different characteristics, one for extra high flow (Si), one for extra high vacuum level (Xi), one for handling low of fluctuating compressed air feed-pressure (Bi/Pi) and finally an extra dirt tolerant design (Ti).
Due to the design of the COAX® multistage ejector in the vacuum pump with no moving parts, there is virtually no maintenance.
First download the manual from the homepage and there you will find the article numbers of the different spare parts.
A single stage ejector is designed for either high vacuum flow or high vacuum level. The multistage COAX® vacuum ejector has a combination of different nozzles providing both high flow and high vacuum level performance in the same ejector. This design also gives lower energy consumption for equal performance.
For the port sizes, go to the product and download the data sheet, which can be downloaded after registering. Specification on thread type is not provided on the webpage.
COAX® is an advanced solution for creating vacuum with compressed air. Based on Piab’s multistage technology, COAX® cartridges are smaller, more efficient and more reliable than conventional ejectors, which allow for the design of a flexible, modular and efficient vacuum system.
A vacuum system based on COAX® technology can provide you with three times more vacuum flow than conventional systems, allowing you to increase speed with high reliability while reducing energy consumption. COAX® cartridges exist in several sizes (MICRO, MINI & MIDI) and models (Bi, Pi, Si, Ti & Xi), making them suitable for every application. The technology ensures excellent performance at both low and high feed pressures. Vacuum pumps based on COAX® technology can operate within the feed pressure range of 0.17 to 0.60 MPa.
The most common problem in a vacuum system is that you have restrictions between the vacuum source and the point of suction, e.g. long narrow hoses. By integrating the vacuum cartridges in your system, you are then able to place the vacuum source close to the point where you need the vacuum. You have minimized the restrictions and will minimize the energy consumption in your system. You will also have a more compact solution.
In lifting applications with suction cups - do not use more vacuum than needed. We normally recommend 60 kPa (18 inHg). Too high of a vacuum level gives lower efficiency and you would use more energy than actually needed.
The most common problem in a vacuum system is that you have restrictions between the vacuum source and the point of suction, e.g. long narrow hoses. By using the combined vacuum pump and gripper, the vacuum is generated at the suction cup. You have minimized the restrictions and will minimize the energy consumption in your system.
The ejector technology has no moving parts thus with virtually no maintenance, it will provide higher reliability. It is also much smaller in size and weight that gives you the possibility to place it closer to the point of suction or where you actually need the vacuum. The mechanical pump also has a much higher noise level and produces heat, meaning that normally you would need to have it in an insulated room.
