■ Mounting instruction

BSP-P300-CAN series pumps are centrifugal pumps that require pre-filled,

The pump is 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: The pump should not be dry-running, even though it can dry-running for 15 minutes (after 15 minutes of dry-running, it will automatically stop the motor), Dry running will make 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 entrance 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 getting stuck in the 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 seawater or other heavy pollution with big grain impurity liquid as the liquid medium.

■ Temperature parameter

Medium liquid temperature: -40℃ to +100℃ (-40°F to + 212°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, excessive or too low voltage and temperature will affect the service life of the motor, and the pump can not be exposed to thermal radiation ambient.

Medium liquid: pure water, liquid mixture (Water with below 60% glycol)

■ Electrical parameter

Connector model and the corresponding electrical properties (see figure 3):

■ 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, and 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.

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

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