Oil
change
First time After 500 hours or 6 months, whichever comes rst. −
2nd. and
subsequent
times
Every 5,000 hours, or every year, whichever comes
rst.
Indoors, etc. at 0 to 35 °C
Every 2,500 hours, or every 6 months, whichever
comes rst.
Outdoors or hot locations, etc., where 0 to 35 °C
cannot be maintained.
- Oil degrades more rapidly when ambient temperature is high or changes radically, and when corrosive gases are present. In such
cases confer with the lubricating oil manufacturer.
(2) Recommended Lubricating Oil
Always use lubricating oils recommended by Sumitomo Heavy Industries as shown in Table 8-5.
Table 8-5 Recommended Lubricating Oils (Equivalent to SP type industrial high-pressure gear oil or JIS K2219)

[1] When using in winter or where the ambient temperature is relatively low, use an oil with a viscosity at the lower end of the range.
[2] For allowable lubricating oil viscosity see Table 8-6. Use within this required viscosity range.

/S
Viscosity at which the plunger pump and motorized trochoid pump
can start.
[3] For a smooth startup use oil with a pour point at least 5
℃
below ambient temperature.
[4] If operating temperature changes within a wide range use a high viscosity index oil that meets requirements [2] and [3].
[5] If regularly operating outside the ambient temperature range of 0 to 40
℃
, some parts of the mechanism may need to be
changed, and lubricating oil might need to be preheated, or cooled. Please consult with us.
