Thick (2.4mm) wall tubing provides stable flow performance with viscous fluids, or against higher delivery pressures (up to 2 bar) or more demanding suction conditions. Because handling thicker wall tubing demands more torque, extension pumpheads may not be fitted to 313D2 or 314D2 pumpheads.

Digital speed control from 3rpm to 400rpm in 1rpm steps. Instantly reversible. Switchable between 100-120V or 220-240V 50/60Hz. Rapid-loading flip-top pumpheads accept seven tube sizes from 0.8mm to 8.0mm bore. Rear panel 25D socket accepts 4-20mA or 0-10V analog auto-control signals. 9D socket accepts RS232 control commands.
