Pressure – vacuum pumps or combination pumps are uniquely designed for the Printing Industry. The demands of the feeder on a sheet fed printing press require vacuum for gripping each sheet while the pressure side, or blast air, is used to be sure the sheets are separated. Our combined pumps reach an ultimate vacuum level of 18″ Hg and maximum pressure of 9 PSIG simultaneously.
Becker pioneered the development of the combined pressure and vacuum pumps when it developed a device called the secondary suction. This secondary inlet port allows a continuous flow of inlet air and lets the compressor operate independently of the vacuum pump. All Becker combined pumps include this design.
Although the Print Market is the main use for these pumps other non-printing customers have found these pumps to be the perfect fit for them.
Vacuum Pressure Pumps
Rotary Vane Oil Free Combined Pumps
Becker’s oil-less rotary vane pressure/vacuum pumps are suitable for higher pressure differences in vacuum and/or pressure applications. Similar to other dry rotary vane pumps, an eccentrically mounted rotor with slots rotates in a cylindrical housing and the precisely fitting sliding vanes move in the slots and separate the individual working chambers. All Becker combined pumps also feature a secondary inlet port that allows a continuous flow of inlet air and lets the compressor operate independently of the vacuum pump, so when the vacuum level is increased the blast air side is not affected.
