Particular attention has been paid to the form of the product chambers when designing the metal pneumatic diaphragm pumps from Almatec. Result: soft contours, smooth flow channels and no dead spaces.

The three pump sizes in the CHEMICOR series permit a maximum delivery volume of 4.5 m³/h (AD 20), 9 m³/h (AD 32) and 24 m³/h (AD 50).

A variety of materials is available for the metal Almatec pumps:

• Housing - stainless steel precision casting 1.4408, 1.4408 polished
• Diaphragms - EPDM, PTFE/EPDM
• Ball valves - EPDM, PTFE

CHEMICOR pumps with a center block made of PE conductive meet the ATEX requirements of the directive 94/9/EG.
