Boosting/circulation/Variable-frequency/Low-noise/centrifugal pump PWM control/Fault diagnosis

The OWP-BL93-200 BLDC Water Pump is a high-performance and efficient water pump designed for various applications. With an input voltage range of 18-30V, this pump is capable of delivering reliable and consistent performance.

Its rated head of 9 meters and rated flow of 1800 L/H ensure efficient water delivery, making it suitable for a wide range of pumping tasks. The pump features a powerful 100W brushless DC motor, which offers high efficiency and low power consumption, resulting in energy savings and reduced operating costs.

One of the notable advantages of the OWP-BL93-200 is its dry running protection feature, which ensures the pump's longevity by automatically stopping operation when there is insufficient water supply. The shield pump structure with magnetic force transmission enhances its durability and reliability.

This water pump is designed to withstand a wide operating temperature range, making it suitable for various environments and conditions. It also incorporates several protection mechanisms such as reverse polarity, overvoltage, over current, overload, and over temperature protection, ensuring safe and reliable operation.

The OWP-BL93-200 BLDC Water Pump incorporates PWM signal speed control, allowing users to adjust the pumping speed according to their specific needs. This flexibility enables precise control and optimization of water flow.

 ■ Attentions

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 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-BL93-300 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 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 .
