Vacuum pump is used for the production and storage of negative pressure for the vacuum plastic forming. Single pump or double pump is depend on you. Double pump can ensure the safety and stability of the system, and guarantee the air consumption while molding large products. 

Technical parameters: 
A. Water-cooled sliding-vane rotary vacuum pump is used, with pressure of over 0.9bar; 
B. Control method: Automatic & manual; 
C. Vacuum pressure tank: 3m3(single pump), 6m3(double pump); 
D. Power for vacuum pump: 3-phase-4-wire 380V, 3KW/pump; 
E. Power for cooling pump: 3-phase-4-wire 380V, 0.5KW
