nopped E4® diaphragm as shown in picture 7). Tighten the
second diaphragm by hand (picture 12). At the same time,
lock the piston rod with a wrench.
Install pump chambers, insert valve seats and balls (check
for any damages and if required replace), mount suction
and discharge manifolds as per the DEPA® IOM.
