To Remove Discharge Flanges:
1. Using a 1⅝” wrench, remove the four 1” nuts from each of the two discharge flanges.
2. Remove each discharge flange from the fluid cylinder. Remove the fluid seals from both the inlet
side and outlet side of each discharge flange. Closely inspect each discharge flange for internal
erosion and corrosion. Inspect the discharge flange threads for wear and damage. The discharge
flange seal surfaces should be thoroughly cleaned and lightly hand polished with a 220 to 240 grit
emory cloth prior to reinstallation.
3. Inspect the fluid cylinder discharge flange bores for erosion and corrosion. Thoroughly clean and
lightly hand polish each bore with a 220 to 240 grit emory cloth prior to reinstalling the discharge
flanges.
4. Using new fluid seals and a coating of light oil, reinstall each discharge flange being careful to
avoid damaging the seal on the inlet side of the flange. Reinstall the four 1” hex nuts on each
flange and evenly tighten them to the proper torque (refer to the Torque Table included in this
manual).
To Remove the Suction Manifold:
1. Using a 1⅛” wrench, remove the twelve 3/4” capscrews which secure the suction manifold to the
fluid cylinder, and drop the suction manifold away from the fluid cylinder.
2. Inspect the suction manifold for internal erosion and corrosion. Remove the three suction manifold
o-ring seals and inspect the seal grooves in the manifold for erosion and corrosion. Inspect the
face and O.D. of the pipe at each end of the manifold for erosion and corrosion. Note: The SPM
®
manifold incorporates a Victaulic “ES” type connection at each end which will accept either a
Victaulic “End Seal Cut Groove” gasket or a Victaulic “Standard Cut Groove” gasket.
The condition of the pipe face at each end of the manifold is important for sealing purposes only
when the “End Seal (ES)” gasket is used.
3. Inspect the bottom face of the fluid cylinder for erosion and corrosion. Thoroughly clean and lightly
hand polish the bottom face of the fluid cylinder with a 220 to 240 grit emory cloth prior to
reinstalling the suction manifold.
4. Using new o-ring seals, reinstall the suction manifold. Reinstall the twelve 3/4” capscrews and
evenly tighten them to the proper torque (refer to the Torque Table included in this manual).
