â– 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.

The TM 40 Series offers multiple component configurations allowing them to beused for either vacuum operation, pressure operation, or alternating vacuum andpressure operations. The innovative, compact design incorporates leading edgetechnologies that allow it to operate harder, quieter and longer, reliabler, highlyefficient.

TM 40 pumps can be mounted in any position and can deliver up to 11 l/ min, 13L/ min ( dual head) depending on the model and will operate against pressures of up to 250Kpa.


Highest Performance/ Size Ratio

Innovative and efficient engineering designs enable the TM 40 Series to push the performance envelope in a lightweight, compact size.

Performs Quieter

Optimized head, chamber, and flow path reduce noise without compromising performance.

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


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:

Industrial pressure and vacuum applications

Portable Analytical Instruments

Medical Diagnostic Equipment

Air Quality Sampling Monitors

Respiration Monitors

Gas or Odor Leak Detectors
