Page 7: Pipe Connections And Sizing
Vmax systems are supplied with an inlet check valve as standard. This valve provides a minimum of resistance close to the pump suction flange to prevent back flow of process gas and seal fluid when the pump is stopped. -
Page 8: Theory Of Operation
The discharge separator/reservoir holds the seal fluid and incorporates the DEKKER patented high-efficiency separator arrangement to separate the seal fluid from the air or gases discharged by the pump. See “Piping and Instrument Diagram” of the Vmax oil-sealed liquid ring vacuum pump system below. - Page 9 2 psig when operating under vacuum conditions. A pressure higher than 2 psig is a sign of high back-pressure in the discharge pipe system. Pressure gauge might show a higher pressure at start-up at low vacuum (0-10" Hg).

10,000 hours of operation Or once per year, change seal fluid. Use DEKKER Vmaxol seal fluid. Life of Standard Vmaxol is 10,000 hours of operation. Synthetic/Food grade Long-life Vmaxol may be changed every 15,000 hours of operation or once a year, whichever comes first. - Page 16 Usually the valve is used to isolate the vacuum system from the piping network. ♦ Inlet Filter (optional): An inlet filter may be installed on the Vmax oil-sealed vacuum pump systems to prevent carry-over of particles into the pump.
