■ Attentions

1.Working ambient temperature:-40℃--120℃, should try to avoid close to three-element catalytic, gas discharge pipe system and engine during the installation, ensure the working environment temperature.

2.The installation position of the water pump should as much as possible close to the low water level , to extend the service life of the pump.

3.Please use the pump far from the dusty environment, the dust is harmful to reduce the service life

4.Pay attention to the purity of the water, avoid to jam and impeller-blocked to reduce the service life of pump

■ Mounting instruction

 
OWP-BL43-300 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 .
