TOPSFLO micro diaphragm liquid /vacuum 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.

A-  Premium duty brush DC motor

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

B-  Economical brush DC motor

lifetime:1,500hours 

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

  •  Small and powerful
  •  Self-priming and excellent for pressure
  •  Dry running, durable and maintenance free
