Vacuum pumps are quoted with a Maximum Water Vapour Handling Capacity, usually in grams/hour. This parameter is determined by the gas ballast flow rate, the running temperature of the pump and the pressure at which the exhaust valve of the pump opens. An oil sealed vacuum pump...
Order a 79103-series pump for general-purpose applications; select a 79104-series pump with chemical-resistant wetted parts for highly corrosive applications. Choose a model with a gas ballast valve when working with condensable gases. BrandTech Vacuum Meter with Digital Di...
Gas ballast is a constructional feature widely applied in many primary vacuum pumps for the pumping of vapours. It permits a pump to operate on vapour duty at nearly full specifications.
