9.5 Suction Manifold and Connections
1) Disconnect the suction line from the suction manifold.
CAUTION: If there is a bladder-type pulsation dampener on the suction system, isolate it or bleed the
nitrogen pressure from the bladder. Failure to do so can result in injury. Idle bladders can rupture and
cause fluid and loose components to be ejected from the suction lines during a valve or fluid end plunger
change. Follow proper safe practices.
2) Remove the suction manifold by loosening the 3/4" screws using a 1-1/8" wrench.
3) Inspect the bottom of the fluid cylinder for erosion and corrosion. Thoroughly clean and lightly
polish the bottom face of the fluid cylinder with 220-240 grit Emory cloth.
4) Remove the o-rings from the suction manifold. Clean out the o-ring grooves, and install new o-
rings.
5) Clean the unit for examination.
6) Examine the suction manifold for erosion, corrosion, or areas that would hinder the surfaces from
sealing properly. Examine the inside welds where the pump inlets connect to the manifold pipe. If
more than 0.050" of material has been eroded or corroded from the inside of the manifold, replace
the suction manifold.
7) Lightly grease the o-rings when reinstalling the manifold and torque the cap screws per Appendix
