When screwing in the diaphragms [15] on the shaft
[16], the holes in the diaphragms must align with the
holes in the centre block [12]. Sometimes it is
necessary to turn the diaphragm back a little bit in
order to align the holes. When putting in the pin
screws [14] take extra care not to damage the
diaphragms [15] with the pin screw thread.

Test run
We recommend you to conduct a test run of the pump before installing it in the system, so
no liquid gets wasted if the pump leaks or perhaps does not start accordingly to wrong
assembly of the pump.
After a few weeks of operation retighten the screws with appropriate torque.
