Vacuum pump and accessories

In this section we offer good range of vaccum pumps for most short and medium size processes with composites.

You will also find a wide range of vacuum accessories to help you develop and maintain your vacuum set-up.

Vacuum pumps are typically classified by the horsepower of the motor, the volume of air displaced in cubic meter per hour (CMH) or cubic feet per hour (CFH), type of pumping mechanism (piston, rotary vane, diaphragm, etc.) and the maximum attainable vacuum pressure in Bar or inches of mercury ("Hg.).

It is very important to match the bag size, desired vacuum level, and pressure with that of the pump for best results. While a smaller pump can often attain a desired vacuum level on a large system, it will take much longer to achieve that level. Also, if a leak is present in a system which exceeds the CMH or CFH rating of the pump, even a partial vacuum will be difficult to achieve. If a pump can not achieve full vacuum in less than five to ten minutes, the pump is probably too weak. Selecting the correct pump for an application is based on total area of the mould. By squeezing as much air out of the bag as soon as possible before sealing the bag and applying the vacuum, the work of the pump can be greatly reduced.
