The all-new 520R low-shear, high-reliability pumphead accepts up to 9.6mm bore tubing for flow rates up to 3.5 litre minute. Sprung stainless-steel rollers, low rotational speeds and a large swept volume make the 520R the gentlest, most powerful pumphead yet. Choose the 520S for manual control, the 520U for analogue auto-control and the 520Du for manual, auto-analogue and RS232 control. The 520U and 520Du accepts 0-10V, 4-20mA, 5V TTL, 24V industrial logic inputs and provides 0-10V, 0-1258Hz speed, 5V TTL, 24V logic outputs.
The 520 drives provide outstanding performance, long life, reliability and great value. Watson-Marlow's modular design allows fast pumphead interchange by the user to provide low pulse and multi-channel pumping options. ... for process ... for science |
