Our TL-C series design features micro centrifugal pumps powered by brushless DC motors. They are designed to be cool, quiet, compact and lightweight. A variety of features, including a seal-less design to prevent leakage, wide range of working voltage, stable performance, long life time, enable the pumps to meet a full spectrum of user needs, with emphasis on ease of installation, operation and maintenance.

Features:
● The micro centrifugal pumps have the three-phase ECM brushless DC motor, high efficiency, low consumption, long life time, multifunctional control, start small power.
● Taken the advanced magnetic drive technology, the rotor-impeller and the shaft are sealed together independently from other parts, without any leak for ever.
● The reliability is because of pump only contains one moving part: the magnetically driven rotor-impeller spins on a single ceramic bearing, high precision, well wear resistance, thus extending the life of this pump beyond existing standards.
● TOPSFLO Unique Closed Impeller -- dynamically balanced, higher efficiency, stronger pressure performance, steady flow, smooths ultra quiet operation.
● Three-phase brushless DC pump can achieve PWM speed control, analog signal (0~5 V) or manual potentiometer speed control, can be achieved on the head and flow regulation.
● Three-phase brushless DC pump have the advantage of various protection functions such as: impeller stuck protection, over-voltage protection, overload protection, over-current protection, reverse polarity protection (optional), dry-running protection (optional).

Definitions:
Dry-running protection (customized functions)
Drive circuitry can detect no or little liquid in pump chamber and will stop the pump to prevent damage, pump is then restarted manually by disconnecting and reconnecting it to the power supply.

Over voltage protection
When the voltage over 28V, the pump will auto-protect and shut off own power supply, when the voltage falls below 28V, the pump will restart automatically.

Over load protection function
This means that when the current is over the rated current, such as can arise if the impeller is stuck due to debris. The pump will automatically stop to prevent damage, and will restart when the current falls again.

Application:
The centrifugal brushless pumps are designed for general, commercial and industrial applications. Ideal for circulation pump applications. They will pump fresh water, seawater, and other liquids that are compatible with the pumps materials and that are of similar viscosity to water.
