Tightening torques
Checking of the tightening torques is necessary after all periods of stoppage, when
temperature variations are a factor and after all transport and maintenance of the pump.
What is more, for proper operation and safety the torque values should be checked frequently
as part of preventive maintenance (please contact Tapflo for interval proposals). Although
pump applications vary, a general guideline is to re-torque the pump every two weeks.
