MiniChem | AODD

MiniChem One-Block technology delivers outstanding benefits, all of which help to:

• maintain levels of safety in hazardous environments and operations
• reduce down time and cleaning costs
• keep operations running and cost-efficient

A PTFE / Teflon double diaphragm pump designed specifically for the safe transfer of aggressive chemicals and other hazardous liquids, at flow rates up to 100 litres/minute through 1/2” and 1” connections.

The MiniChem is machined from one solid block of PTFE; a unique patented concept based on Flotronic’s existing One Nut Air-Operated Double-Diaphragm design. A key benefit of the ‘One-Block’ design is that it avoids the need for separate manifolds. This means no manifold seals and therefore no potential leak paths.

The ‘One-Block’ approach enhances the ease of maintenance benefit which the ‘One-Nut’ design delivers. The pump is held together by one nut on the side opposite the external air valve – allowing in-line diaphragm replacement in less than 15 minutes and a complete strip-down and re-build possible in less than 20 minutes. One-Block means that Minichem maintenance need focus only on One-Nut disassembly … and on the ball valves only when necessary.

Flanged as well as threaded BSP versions of the MiniChem are available, ensuring full compatibility with existing PTFE-lined pipework.

All non-wetted MiniChem parts are in Polypropylene and Stainless Steel and ATEX approved versions are also available in both FDA approved PTFE and anti-static PTFE. With environmental protection in mind, Diaphragm Rupture Protection and fully pneumatic Alarm Systems are available.

Applications:

• Chemical, pharmaceutical and similar industries
• Pilot plants (often in sampling lines)
• Emergency pumps for hazardous chemical recovery.
