■ Overview

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.

1.Highest Performance/Size Ratio
Innovative and efficient engineering designs enable the TM30A 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 model code is identical to the order number,it is made up as follows:
A Motor- Premium duty brush DC motor, lifetime 3,000hours
(Note: other lifetime choices also available: C Motor , D Motor ,E Motor or F Motor- 15000hours coreless brushless
