Product Information

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 transfer redto a diaphragm by means of a connecting rod, an elastic diaphragm, which in conjunction with an inlet and outlet valve creates a pumping action.

The TF30B Series offers multiple component configurations allowing them to be used for either vacuum operation, liquid transfer, or alternating operations.The innovative, compact design incorporates leading edge technologies that allow it to operate harder, quieter and longer, reliabler, highly efficient.

TF 30B pumps can be mounted in any position and can deliver up to 350 ml/min depending on the model and will operate against pressures of up to 1 bar.
