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 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.

The Double head pump TMD40 Series offers multiple component configurations allowing them to beused for either vacuum operation, pressure operation, or alternating vacuum and pressure operations. The innovative, compact design incorporates leading edge technologies that allow it to operate harder, quieter and longer, reliabler, highly efficient.

Double head pump TMD 40 pumps can be mounted in any position and can deliver up to 12 l/min, 17L/min (dual head) depending on the model and will operate against pressures of up to 220Kpa.

Features
1.Highest Performance/Size Ratio
Innovative and efficient engineering designs enable the TMD 40 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 15,000 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 PTFE FKM 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
