These oil-free pumps are ideal for filtering, desiccating, cell harvesting, vacuum blotting, aspirating, degassing, and distilling. They are suited for applications requiring a rough vacuum of 648 to 752mm Hg (251/2 to 2919/32" Hg) and free air displacement of up to 201L/min. (7.1cfm). They are available in standard and chemical-duty models to accommodate pumping of a variety of vapors and gases.
Standard-duty pumps are protected from moisture and corrosion and use a WOB-L piston pumping mechanism. A liquid trap attached to each pump traps water if it is accidentally drawn into the line. Discharge air noise is muffled with a silencer. Vacuum gauge included.
Chemical-duty pumps utilize corrosion-resistant PTFE on all wetted surfaces, allowing the pumps to withstand aggressive solvent, base, and acid vapors. Pumps also feature Kalrez*/Chemraz* elastomer valves. Discharge air noise is muffled with silencer. On 21150-410, a gas ballast valve acts to minimize vapor condensation inside the pump.
The 115V, 60Hz maintained on/off foot switch (14233-684) allows hands-free operation of pumps. Made of durable black painted steel, the switch features a nonskid base and foot treadle pads to ensure secure footing during repeated operations. Comes with a 2.4m (8') cord.
Note: Standard-duty pumps are not recommended for pumping acid, base, or organic vapors.
