When assembling components of a pump, use bolts and nuts. These must be tightened with the appropriate tightening torques.
Normally an impact wrench is used for this. It should be set to the standard tightening torque for each size. When tightening stainless screws or nuts on other stainless components, it is also necessary to apply a suitable lubricant to the screws. To prevent the threads from seizing, first tighten the parts carefully by hand before proceeding with an impact wrench. We recommend that you then check the tightening torque with a torque wrench.
