Opening the QD cover
1.
Depressurise the entire pump unit.
2.
Shut off the connected pipes if possible.
3.
Drain the pump as much as possible. Attention! Any remaining fluid will flow out of the machine when
the QD cover is dismounted.
4.
Depressurise the buffer chambers if necessary
Chap.
" Buffer chamber".
5.
Undo hexagon nuts (3) on the twelve hexagon head bolts or threaded rods on the QD cover (4).
6.
Remove the screw plugs (1) carefully, as medium could spurt out due to pressure in the pump
housing. Where appropriate, cover the plugs to be removed with a cloth or similar item.
7.
Undo strain bolts (2).
8.
Using the hexagon head bolts (M10 for VX136, M12 for VX186/215/230), the QD cover can be
pressed off via the threads (6) until the QD cover is loose.
Attention! Do not tilt the QD cover; press it off evenly by hand (no tools)!
In the case of pumps with double hinge: press off the QD cover evenly and turn it to one side
