Parameter
■ Temperature range
Medium liquid temperature: -40℃ to +85℃ (-40°F to + 185°F)
Working ambient temperature: -40℃ to +120℃ (-40°F to +248°F)
Storage temperature:-40℃ to +70℃ (-40°F to +158°F)
(up to 100 ℃, but it will shorten the service life)
■ System pressure
-0.2 to 2.5 bar ( 100℃ (212°F).
The service life is more than 20,000 hours based on the rated
voltage and 36℃(86°F) ambient
temperature.

Although the motor can be used in a wide range of voltage and
temperature, but excessive or too
low voltage and temperature will affect the service life of the
motor, the pump can not be
exposed to thermal radiation ambient.

■ Electrical parameter
Application guidelines
OWP-BL43-408T series pumps are centrifugal pumps which require
pre-filled, The pump installed in the lowest position of the system
to ensure that the impeller is always immersed in the liquid, or
pre-filled the pump before power on .
1: Pump should not be dry-running, even though it can dry-running
for 15 minutes (after 15 minutes dry-running, it will automatically
stop), Dry running will makes noise, also increasing abrasion to
the shaft and shaft sleeve.
2:Use the recommended diameter pipe connecting the pump inlet, if
you use a smaller diameter hose pump inlet, Due to the negative
pressure in the pump, the outside air easier enter to the pump
through the pipeline, it will make the pump performance
degradation, and also the air
bubbles make damage to the pump.
3: As viewed from the pump inlet direction, the impeller rotates
clockwise (see the arrow on the outlet port).
4: The pump can be installed vertically or horizontally mounted
(see figure 1 ) When installed vertically, the outlet port should
be upward .
5:In order to avoid the dry- running (air get stuck in
impeller),the water pump outlet port should be vertical or in the
upper of the impeller. (see figure 1 )
6: The connected pipe should be vertically mounted (or no elbow in
20cm )to make the air discharged easily, the outlet pipe should not
be used less than 90 degrees elbow (see figure 2).
7: Can't use the seawater or other heavy pollution with big grain
impurity liquid as the liquid medium .
