WATER PUMP
The following cautions are operational limitations of
Mega water pumps. Failure to heed these cautions
may result in reduced pump life and severe water
pump damage.
Do not operate the water pump in a dry sump.
Operating the water pump with a dry sump will result
in water pump component damage and reduced
service life.
Engaging/disengaging the water pump above LOW
IDLE may result in water pump component damage
and reduced service life.
Limit water pump operation to 2.5 minutes when in a
no-flow condition (not flowing water through spray
heads, dump bar, water cannon, drain valve or hose
reel). Water pump operation in a no flow condition
will cause overheating of the water pump and
damage to the shaft bearings and seals.
Avoid any sudden stoppage of water pump e.g.;
disengaging water pump above LOW IDLE. Stopping
water pump suddenly above LOW IDLE will result in
shaft, impeller and drive motor damage.
Water pump RPM must not exceed the specifications
listed below with engine at HIGH IDLE. Failure to
ensure water pump speed is at or below
specifications will result in reduced spray system
component service life.
If water pump RPM is to out of the desired range,
adjust the water pump hydraulic drive motor flow
control valve to obtain specified RPM.
PUMP MODEL RPM
M-4 PUMP 1,900 ± 50
