The PIAB pump is the core of the efficient, safe and economical systems based on products from PIAB. PIAB vacuum pumps are driven by compressed air which is expanded in several stages. This offers the following three major benefits: The pump efficiency is exceptionally high. The energy consumption is very low – sometimes almost zero – due to the Vacustat energy-saving system.
And the pumps are insensitive to pressure drop in the pipe work, since they are designed to operate at low compressed air supply pressure.  PIAB vacuum pumps offer further benefits. They are compact, reliable and quiet, and have short response time. They also maintain a good working environment since they emit neither heat nor oil mist. The absence of moving parts minimizes maintenance.
PIAB's new L Series Vacuum Pumps are designed with the packaging industry in mind. These pumps provide 30%-70% more vacuum flow . The L Series will handle high leakage rates in applications such as opening and handling cartons or cases while still providing enough vacuum pressure to get the job done. The new Low Pressure M Series vacuum pumps will provide 27 -inHg of vacuum at only 49 psi inlet pressure. Finally, there is an air-driven multi-ejector vacuum pump that can handle low or fluctuating compressed air pressures while still providing a deep vacuum level

What is the difference between a sealed and a Nonsealed system

With sealed systems, the capacity of the pump is determined by the time required to evacuate the system to a set vacuum level. This is called the evacuation time of the pump and is normally specified in milliseconds per litre (ms/l).

With non-sealed systems (lifting of porous materials) the case is different. To maintain the desired vacuum level the pump must have the capacity to pump away the air leaking in. By establishing the leaking flow, it is possible, by reading the pump data, to find the right pump for the application in question.

 

When the leakage occurs through a porous material or in an unknown way, the flow can be established by a test with a vacuum pump. The pump is connected to the system and the obtained vacuum level is read. (It should be at least -40 kPa (-12inHg)). The flow that is pumped away at this vacuum level can be seen on the page of the particular pump (in the Vacuum Automation catalog). This flow roughly corresponds to the leaking flow.
