    * Mounting instruction  
    DKB60 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 threaded 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 .


    * Temperature parameter
    Medium liquid temperature: -25?to +105?(-13°F to + 221°F)
    Working ambient temperature: -10?to +100?(14°F to +212°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

    * 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% glycol)

    * Attentions
    1. Working ambient temperature:-10?-100? 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. In order to reduce water resistance, should as much as possible to reduce the number elbow
    in piping in the installation, ensure no any elbow within 20 cm from 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.
