7. GENERAL INFORMATION ABOUT PUMP
USE
The KE pump has been designed to pump fresh and
filtered (360 micron max.) water at room temperature.
Special versiona are available for pumping water up to
185oF and for reverse osmosis units.
7.2 Max flow and pressure ratings
The performance data indicated in the catalog and on the
rating plate refer to the maximum performance of the
pump. The use of the pump below the rated performances
does not allow the drop in power absorbed to be balanced
by altering the pressure or volume of the pump above its
maximum value.
7.3 Lowest operating RPM
The lowest operating speed of the crankshaft for all KE
pumps (all versions) is 500 RPM.
8. CONNECTIONS AND PLUGS
KE pumps are provided with (Fig. 3):
1 - 2 inlet ports IN Ø 1” NPT
Suction line connection to either inlet port is
acceptable, the port not being used should be
sealed with the correct plug.
2 - 2 outlet ports OUT Ø 1/2” NPT
3 - 3 outlet ports OUT Ø 1/4” NPT (designed for
pressure gauge and safety valve only)
7.1 Water temperature
The water temperature is critical for the pump
life: the higher the water temperature, the
more likely it is to create cavitation, resulting in
premature seal and valve failures.
For such conditions, use HT series pumps.
