Dual-Headed Peristaltic Pump Watson Marlow 520S IP 31

Article N° PE – 00648

It is a dual headed peristaltic pump which thus works with low pulsation. With the specially
developed glass damper the pulsation is almost zero.
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.

Suitable applications
Peristaltic pumping is ideal for most fluids, including viscous, shear-sensitive, corrosive and abrasive fluids, and those containing suspended solids. They are especially useful for pumping operations where hygiene is important. Peristaltic pumps operate on the positive displacement principle. They are particularly suitable for metering, dosing and dispensing applications. Pumps are easy to install, simple to operate and inexpensive to maintain.
The pump can be used for sterile applications when the hose elements are sterilised in the autoclave.

Nisco application
Used for VAR D continuous and VAR E in case of sterile application and/or abrasive particles.
