Product Description



TOPSFLO micro diaphragm pumps are based on a simple principal,


the circular power from the motor is converted into oscillating movement by an


eccentric, which moves up and down its central point, this motion is then transferred


to a diaphragm by means of a connecting rod, an elastic diaphragm, which in


conjunction with an inlet and outlet valve creates a pumping action.

Product Feature


1. Oilless, environmental protection media, can be used in the food industry

2 .Diaphragm liquid pumps have good self-priming function

3. Can run dry, there is no danger or damage

4. 24 hours continuous running is workable (will not stop working because of overheating)

5. Compact design

6. Can be made by PTFE (polytetrafluoroethylene) membrane, FPM valve (FKM), which are the good materials of anti-acid and alkali


7. Patented diaphragm structure, long maintenance-free life expectancy. ( if want to replace the diaphragm by your own, just need unscrew the head screws and do the replacement)




Product Advantage


1.Adopt enhanced importing dual bearings, which arevery wearable, can well match with 15,000 hours pump lifetime &



2.Adopt metal balance cake, the the pump has good balance performance, very small vibration. (Domestic counterparts with plastic weights, has big vibration


3  With imported rubber diaphragm, high purity, good wear resistance. Besides, there is EPDM, PTFE valve, EPDM, FPM diaphragm optional, all these materials have better chemical resistance capability. .  


4  The overall design & inner structure are the same as foreign famous KNF, Parker brands, the overall design is reasonable & compact, which assured TOPSLFO pumps’ high performance and low noise, low vibration and long lifetime.



5.Our Micro Diaphragm Pumps are available with a choice different drive motors.




 A motor B motor C motor D motor H motor

A-  Premium duty brush DC motor

lifetime 5,000hours,longer endurance lifetime than other normal DC membrane pump

B-  Economical brush DC motor



C-  Coreless Brushless DC Motor  

A brushless electronically commutated dc motor (electronics integrated in motor), the motor runs vibration and spark free, almost silently, is very dynamic and extremely durable, ideal life-time 15000 hours

D-  Coreless Brushless DC motor with outer controller
With all advantages of coreless brushless DC motor, ideal life-time 15000 hours, and outer controller can realize more control functions of PWM or 0 -5V speed adjustment, brake, ~ instant starting work


H- Brushless DC Motor

Long lifetime 10000hour
