23.4 313D and 314D flow rates
Flow rates were obtained using silicone tubing with the pumphead rotating clockwise,
pumping water at 20°C with zero suction and delivery pressures. For critical applica-
tions determine flow rates under operating conditions.

Note: 314D pumpheads should run no faster than 300 rpm when in continuous use.
Speeds up to 400 rpm are permissible for intermittent use.
