7.INFORMATION ABOUT PUMP USE
The MK pump has been designed to operate
with filtered water (see paragraph 9.7) and at
maximum temperature of 104
0 F (40 0 C).
Other fluids may be used only upon the
approval of The Customer Service
Department .
7.2 Max Flow Rate and Pressure Values
The performance values indicated in the catalog refer to
the maximum performance of the pump. Regardless of the
power used, pressure and maximum RPM values indicat-
ed on the plate may not be exceeded unless expressly
authorized by the Customer Service Department.
7.3 Lowest RPM
Any RPM value different from what is indicated in the per-
formance table (see chapter 5) must be expressly author-
ized by the Customer Service Department.
7.4 Recommended Lubricant Oil Types & Manufacturers
The pump is delivered with lubricant oil compliant with
room temperatures ranging between 32
0 and 89.6 0 F (0 0
and 30 0 C ). Some recommended lubricant types are indi-
cated in the table below; these lubricants are treated with
additives in order to increase corrosion protection and
resistance to fatigue. As an alternative, Automotive SAE
85W-90 gearing lubricants may also be used.
7.1 WaterTemperature
The max water temperature is 104 0 F (40 0 C).
Nonetheless, it is possible to use the pump at
temperatures of up to 140 0 F (60 0 C) for short
periods of time. In this case we advise con-
sulting the Customer Service Department.

Check the oil level by using the oil level dipstick (1), fig. 3.
Refill if needed from the oil cap (3), fig 3. Correct oil level
inspection is done with the pump at room temperature; oil
is changed with the pump at working temperature, by
removing the rear plug (2), fig 3..
Checking and changing oil is to be carried out as indicated
in Chapter 11. The amount required is 456.5 oz. (13.5
liters).
In any case, oil must be changed at least
once a year since it may deteriorate by
oxidation.
For room temperatures that differ from that men-
tioned earlier, follow the indications contained in
the diagram below, keeping in mind that the oil
must have a minimum viscosity of 180 cSt.
Exhausted oil must be collected in an appro-
priate recipient and disposed of in appropri-
ate locations. In absolutely no case may it be
dispersed into the environment.
