ALMATEC BIOCOR
The ALMATEC BIOCOR series is based on the functional principle of double diaphragm pumps. The basic configuration consists of two external pump housings with a center block between them. Each of the pump housings contains a product chamber which is separated from the center block by a diaphragm. Both diaphragms are interconnected by a piston rod.
Controlled by an air control system, they are alternately subjected to compressed air so that they move back and forth. In the first figure, the compressed air has forced the left-hand diaphragm towards the product chamber and displaced the liquid from that chamber through the open valve at the top to the discharge port.
Liquid is simultaneously drawn in by the right-hand diaphragm, thus refilling the second product chamber. When the end of the stroke is reached, it reverses automatically and the cycle is repeated in the opposite direction. In the second figure, liquid is drawn in by the left-hand diaphragm and displaced by the right-hand diaphragm. The liquid is displaced - and thus conveyed - by the compressed air. The diaphragms merely serve as barriers and are not pressurized. This is a fact of decisive importance for the service life of the diaphragms.
The BIOCOR series is available in two pump sizes B 20 and B 32.
Materials of construction: The material for the wetted housing parts is electropolished SS 316 L (Basel Standard II, ferrite content < 1%) with a surface roughness of ≤ 0.4 μm. The frame is made of 1.4404 and the center block of polyethylene conductive. The suction and discharge ports are suitable for Tri-clamp or different sanitary threads (Naue, Neumo, DIN 11851, DIN 11864). The diaphragms, ball valves and O-rings are made of PTFE or EPDM (FDA); other materials on request.
