5.1.8 Pump
The pump (shown in Figure 1) uses a flexible Nordel liner which is
actuated by a roller on an eccentric. This liner requires oiling weekly. The
pump is equipped with an oiler which holds a large supply of oil. Use the
following procedure to oil the liner:
• Fill the oiler. (This needs to be done only occasionally.)
• Once the oiler is filled, it is only necessary to open the toggle
valve on the top of the oiler.
• Shut off the pump and let 7 or 8 drops of oil fall in the sight
glass of the oiler.
• After about two minutes, restart the pump.
• Close the toggle valve on the oiler when finished.
If the liner is oiled routinely, it should last about 6 months to a year.
Replacement of the liner will restore any noticeable loss in pumping
efficiency.
Any water coming out of the pump liner vent line (at the bottom of
the separator) is an indication that the liner is worn through and needs to be
replaced. Detailed pump maintenance instructions can be found in the
Appendix of this manual.
Note: Use only Venton Pump oil or pure silicone oil of 2000 centistokes
viscosity. Do not use organic oil.
5.2 Troubleshooting
5.2.1 General
Trouble shooting information contained herein is limited to the elec-
tronics of the system. It is felt that malfunctions occurring in the pneumatic
portion of the system can be remedied by personnel familiar with valving,
regulation, and standard mechanical engineering. The electronics portion
of the system, however, includes advanced solid state, integrated circuitry.
Technicians involved with trouble shooting the electronics of the system
should be familiar with common diagnostic equipment and techniques.
