  • Diaphragm Liquid Pump
■ Overview
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.

Small and powerful
Micro design and maximum performance resulting from built-in technology are the outstanding characteristics of this product.
Self-priming and excellent for pressure
Sophisticated diaphragm technology and precise valve structures enable performances from 8.85 in .Hg suction and 14.5 PISG pressure.
Dry running, durable and maintenance free
The carefully considered design of these pumps allows them to be run dry and ensures safe operation and a long life even under the most severe conditions.
Lasts Reliably Longer
Using the advanced diaphragm elastomer and superior brushless motor design sets the highest benchmark for service-free operation that exceeds 10,000 hours.
Uncontaminated flow
No contamination of the media due to oil-free operation
Little vibration
Because of leading edge technologies, top quality bearing, superior brushless motor
High level of gas tightness
thanks to stress-optimised structured diaphragm, newly-designed valves and sealing systems, precise placement of the pump head
Extreme chemical resistance
The use of chemically resistant materials optional such as PTFE FKM or other ,material combinations for the parts which allows the corrosive gas to be pumped.
Optimal solution for your application
A wide standard range of materials, motors , voltages configurates multiple components system selected
