Pump Features
These KNF pumps are compact, lightweight and easy to use for your flask fil-
tration, vacuum manifold and vacuum blotting applications. Our models use
premium, corrosion-resistant wetted parts. All are fitted with KNF’s patented
multi-port valve system that increases performance and tolerates any liquids
accidentally drawn into the system without loss of performance.
Models are available with either a vacuum or pressure gauge and a conve-
nient machined-brass bleeder valve for fine adjustment of performance.
Needle bounce is negligible.
The ball-bearing motor is fan-cooled and is permanently lubricated. The
heads and valves are easily disassembled for occasional cleaning without the
need for special tools or training, and can be reassembled in minutes.
