About this item
These oil-free pumps are ideal for basic lab operations.
- Discharge air noise is muffled with a silencer
- Not recommended for pumping acid, base, or organic vapors
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.
The 115 V, 60 Hz maintained on/off foot switch (14233-684, sold separately) 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 2.4 m (8') cord.
They are suited for applications requiring a rough vacuum of 648 to 752 mm Hg (251/2 to 2919/32" Hg) and free air displacement of up to 201 l/min. (7.1 cfm).
