Membrane Pressure Vessel Relocation
Use ONLY size –8 hydraulic hose, p/n PL-HS-1/2HP, for high pressure connections. Pay
attention to the direction and flow path of the factory installed hoses before disassembly. Make
sure that you reinstall the new hoses in the same manner.
The high pressure fittings are typically pre-installed at the factory. The fittings on the Spectra-
Pearson Pump seal with an O-ring and require no Teflon tape or pipe thread sealant. The fittings
on the pressure vessels are UNF Straight Thread and pre-installed at the factory. These fittings
should not be disassembled, contact the factory if further installation options are necessary.
Follow the high pressure hose connection instructions on the next page. Carefully measure
the total assembled length from fitting to fitting. It is usually best to assemble one end of the
hose fitting, connect it, lay out the hose length required, then mark and cut the hose to length,
taking into account the assembled length of the fitting. A 90 degree bend in a tube is better than
a 90 degree fitting. Do not exceed a 5” (13cm) minimum radius bend.
When connecting the hoses to their components, be sure to hold the fitting body with a wrench
during the final tightening. Of special note are the fittings on the membrane housing seal, these
fittings are national pipe thread and must be properly supported to ensure leak-free service.
