21.12 501RL and 501RL2 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. The important factors are suc-
tion and delivery pressure, temperature and fluid viscosity. Tube life will be reduced
when pumping against pressure.
