Section I – Introduction A. Purpose of Manual Model Codes – There are many variations within each basic model series, which are covered by variables in the model This manual has been prepared to assist the users of code. Table 2 is a complete breakdown of the code covering these units.
Model Code V 2 1 0 - 8 W - 1 F C - C 8 - 12 - L - * Vane pump Capacity in GPM (@ 1200 RPM) Relief Valve Setting (V200 only) C – 750 PSI D – 1000 PSI Series Wide Ring (V200 only) E –...
Section III – Principles of Operation A. Pumping Cartridge as the vanes pass the inlet sections of the cam ring. This results in a low pressure condition which allows atmospheric As mentioned in Section II, fluid flow is developed by the pressure to force fluid into the chambers.
3. When pump delivery is more than the flow rate 4. If pressure in the system builds up to the relief valve determined by the orifice plug, pressure builds up across the setting (Figure 4C), the pilot poppet is forced off its seat. orifice and forces the spool open against the light spring.
3. The number of bends in tubing should be kept to a minimum to prevent excessive turbulence and friction of oil flow. Tubing must not be bent too sharply. Recommended radius for bends is three times the inside diameter of the tube. E.
3. Certain other types of petroleum oils are suitable for Cleanliness Mobile hydraulic service if they meet the following provisions: Thorough precautions should always be observed to insure a. Contain the type and content of antiwear the hydraulic system is clean: compounding fould in MS crankcase oils or have passed pump tests similar to those used in developing the antiwear 1.
Section V – Service, Inspection and Maintenance A. Service Tools D. Adjustments No special tools are required to service these pumps. No periodic adjustments are required other than to maintain proper shaft alignment with the driving medium. B. Inspection E. Lubrication Periodic inspection of the fluid condition and tube or piping connections can save time-consuming breakdowns and Internal lubrication is provided by the fluid in the system.
Troubleshooting TROUBLE PROBABLE CAUSE REMEDY Pump not delivering fluid Driven in the wrong direction of rotation The drive direction must be changed immediately to prevent seizure. Figure 9 shows the correct ring position for each direction of rotation. Coupling or shaft sheared or Disassemble the pump and check the disengaged.
Section VI – Overhaul NOTE light score marks by lapping. Replace any heavily scored or badly worn parts. Complete cartridges are available in service kits for rebuilding these pumps. Refer to catalogs listed in 3. Inspect the vanes for burrs, wear and excessive play Table 1 for part numbers.
