This listing is for a Watson Marlow 520S Peristaltic Pump. The unit is in full working condition and is ready for immediate release. 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.
