NLGI Grade 2 specifications. Minimum dropping point
355 degrees F., operating temperature range of – 10
degrees F to 240 degrees F. Obtain grease from your
local supplier.

j. Consult the driver manufacturer’s instructions for

3-3. TROUBLES. To reliably establish the
performance of either the pump or driver, instruments
such as tachometers, pressure gauges and electric
meters must be in proper working condition and
preferably of recent calibration. In many cases, much
time and expense have been expended with faulty
instruments. Table IV lists a number of troubles
commonly occurring. If unable to determine the cause
and correct the trouble from the list, refer the problem to
the Peerless Pump representative.
