34 720RE and 720R flow rates
Flow rates were obtained using silicone tubing with the pumphead rotating clock-
wise, pumping water at 20C with zero suction and delivery pressures. For critical
applications determine flow rates under operating conditions.
Note
: these figures refer to the performance of a single pumphead; where twin
pumpheads are used, the figures should be doubled.
