PARAMETER

■ Performance parameter

■ Temperature parameter
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.

■ 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)

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 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 .
