Bextreme Shell OWP-BL43-426T SERIES brushless DC water pump
Boosting/circulation/Variable-frequency/Low-noise/centrifugal pump
PWM control/Fault diagnosis
■Description
The OWP-BL43-426T automotive water pump is a high-performance and
reliable solution for various water pumping applications. Designed
to operate within an input voltage range of 18-32V, this pump
offers a rated head of 17 meters and a rated flow of 2400 liters
per hour. With a power consumption of 240W, it efficiently meets
your pumping needs.
This water pump is equipped with several advanced features,
including dry running protection to prevent damage in case of low
water levels, a centrifugal pump for effective water circulation,
and magnetic force transmission for improved efficiency. Its IP68
waterproof rating ensures durability and performance even in
challenging environments.
Additionally, the OWP-BL43-426T is known for its low noise
emission, generating less than 61dB during operation. With PWM
signal speed controlling, you have precise control over the pump's
speed.
The wide range operating temperature makes it suitable for use in
diverse climates and conditions. It also offers diagnostic signal
output, providing important feedback on the pump's performance for
easy troubleshooting.
Safety features are integrated into this water pump, such as
reverse polarity protection, overvoltage and overcurrent
protection, overload protection, and over-temperature protection.
These safeguards ensure the longevity of the pump while protecting
it from potential damages caused by electrical abnormalities.

■ Mounting instruction
OWP-BL43-426T 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 .
