■ Performance parameter
■ Voltage range
Rated 24V water pump, workable range 18V - 32V
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.
Medium liquid: liquid mixture (Water with below 60% glycol)
■ Electrical parameter
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 fault 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 .
