Setup; Tubing Size Selection - Barnant Company manostat VARISTALTIC SIMON Serie Manual De Operación

Unpack the pump and retain all packing material until proper product operation has been verified. Select the tubing
according to the flow desired, while considering chemical compatibility and tubing life. Refer to the enclosed Chemical
Resistance Chart (part no. A-1299-5030) to select appropriate type of tubing for the liquid in use.

TUBING SIZE SELECTION

Flow rate is determined by the size of the tubing in the pump head. When tubing links are used, best performance will
be achieved when input and output tubing connected to the link are the same ID as the link. All tubing inside the
pump head must be surface-printed MANOSTAT tubing.
Simon, Vera and Preston pumps accept tubing ID sizes of 1/32 in. to 5/16 in.
For best results, select a tubing size with a mid-range at the desired flow rate to be pumped. The table below gives an
average of flow rates measured with water at standard pressure and temperature. No lift or discharge pressure is
represented.
