■ Overview

TOPSFLO micro diaphragm pumps and compressors are based on a simple principal,the circular power from the motor is converted into oscillating movement by aneccentric, which moves up and down its central point, this motion is then transferredto a diaphragm by means of a connecting rod, an elastic diaphragm, which inconjunction with an inlet and outlet valve creates a pumping action.

1.Highest Performance/Size Ratio
Innovative and efficient engineering designs enable the TM40A Series to push the performance envelope in a lightweight, compact size.
2.Performs Quieter
Optimized head, chamber, and flow path reduce noise without compromising performance.
3.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.
4.Uncontaminated flow
no contamination of the media due to oil-free operation
5.Little vibration
Because of leading edge technologies, top quality bearing, superior brushless motor 
6.High level of gas tightness
Thanks to stress-optimised structured diaphragm, newly-designed valves and sealing systems, precise placement of the pump head
7.Extreme chemical resistance
The use of chemically resistant materials optional such as FFPM, PTFE, FPM or other material combinations for the parts which allows the corrosive gas to be pumped.
8.Optimal solution for your application
A wide standard range of materials, motors , voltages configurates multiple components system selected

Wetted material options: 
1.Optional membrane materials:
EPDM for normal air 
PTFE for corrosive air,like acid, alkali air, ozone etc.

2.Optional valve materials:
EPDM for normal air 
FPM for corrosive air, like acid, alkali, ozone,etc.

The versatility of TOPSFLO pumps allows a wide field of applications to be covered. Over many years our pumps have proved themselves in the following areas:
