Dual-Channel Variable-Speed Compact C/L  ®  Pumps

c/L pump 

Contamination-free two-channel pumping in a compact format—ideal for analyzer, flow cell, and perfusion applications
Stackable, compact 1/4-DIN housing—mount in your equipment rack or place on your lab bench. (To mount, order brackets 77120-03 at right).
Separate single-turn speed control and cw/off/ccw switch with green LED power indicator—maintain speed setting when you turn pump on/off or reverse direction.
Reversible permanent magnet DC motor; purge fluid before or after pumping; pump fluid in either direction.
Remote control connections on back of pump; start/stop pump with a contact closure.
Max button runs pump at maximum rpm—prime or rapidly flush tubing.
Pump head is constructed from polyphenylene sulfide (PPS), stainless steel (SS), and features acetal co-polymer rollers. PPS and SS promote longer life and the six roller construction provides a low-pulsation flow.
Pump head has average fixed occlusion for tubing; no need to adjust occlusion when changing tubing.
Maximum suction lift of 5 ft (1.5 m); maximum pressure 15 psi (1.0 bar).
