TIGHTENING TORQUE TABLE
The following table shows the tightening torques referred to the construction components and their mate-
rials.
Tightening must be carried out in compliance with the tightening torques indicated by the Manufacturer
and expressed in Nm (Newton metre) referred to each model and construction material.

Excessive tightening (especially on plastic pumps), can cause dangerous tensions on some components
