Peristaltic pumps are the simplest possible pump, with no valves, seals or glands to
clog or corrode. The fluid contacts only the bore of a tube, eliminating the risk of the
pump contaminating the fluid, or the fluid contaminating the pump. Peristaltic
pumps can operate dry without risk.
Easy to install, simple to operate and inexpensive to maintain, peristaltic pumps are ideal for most fluids, including viscous, shear-sensitive, corrosive and abrasive fluids, and those containing suspended solids. Suitable for metering, dosing and dispensing applications.
520S drive offers manual control via a large-key membrane keypad: speed adjustment; run and stop; forward/reverse; "Max" key for rapid priming and purging.
Supply voltage/frequency: 100-120V/200-240V 50/60Hz
Flow rates from 4 micro-litres/min up to 2.4 liter/min
Precise 2,200:1 speed control range from 0.1 to 220 rpm in 0.1 rpm increments
Large speed/flow display and easy to use tactile membrane keypad. Incorporates keypad lock
Manual control and flow rate calibration
MemoDose for accurate single shot dispensing
