■ Model Specifications
■ Mounting instruction
OWP-BL93-300 series pumps are centrifugal pumps which require
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 30 seconds (after 30 seconds 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 .
Medium liquid temperature: -40℃ to +85℃ (-40°F to + 185°F)
Working ambient temperature: -40℃ to +85℃ (-40°F to +185°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 12V water pump, workable range 9V - 16V
Rated 24V water pump, workable range 18V - 30V
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: pure water, liquid mixture (Water with below 60%

|91%≤duty≤100%||Max speed running|
1. Working ambient temperature:-40℃--85℃, should try to avoid close
to three-element catalytic, gas discharge pipe system and engine
during the installation, ensure the working environment
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.
4. Please use the pump far from the dusty environment, the dust is
harmful to reduce the service life
5. Pay attention to the purity of the water, avoid to jam and
impeller-blocked to reduce the service life of pump
