The 70,000 to 300,000 cps range in viscosity fluids require more pressure differential to to move rapidly. General laboratory vacuum of 1/10 atmosphere may not move these fluids rapidly and efficiently. Vacuum systems below 1/100 of atmosphere pressure will provide sufficient pressure differential for these fluids. Please select the number of ports/turrets/nozzles in your system form the options below to arrive at the pumping speed required.
