■ Model Specifications
DKB60TSB-24G 24 V
■ Mounting instruction
DKB60TSB 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 temperature.
■ Voltage range
Rated 24V water pump, workable range 16V - 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)
