Offering a robust leak-free bolted design, Versamatic’s 2" (51mm) bolted metal air-operated double-diaphragm (AODD) pump is engineered to safely seal when pumping aggressive chemicals. The 2" AODD pump offers an ideal combination of flow, size and portability as compared to other pump models, with a maximum flow rate of 163 gpm (617 lpm). As an ATEX diaphragm pump, it meets compliance requirements for use in potentially hazardous environments, including mining.

The 2" is available in the following materials:

• Aluminum
• Stainless Steel
• Cast Iron
• Alloy C

ATEX stands for atmospheres explosibles and is an acronym for the standard set by the European Parliament & Council of the European Union. It’s recognized throughout the European community as the safety standard for equipment used in potentially explosive environments.

ATEX Pumps—Conditions for Safe Use

• ATEX-compliant pumps are suitable for use in explosive atmospheres when the equipment is properly grounded in accordance with local electrical codes.
• Conductive polypropylene, conductive acetal or conductive polyvinylidene fluoride (PVDF) pumps are not to be installed in applications where the pumps may be subjected to oil, greases and hydraulic liquids.
• When operating pumps equipped with non-conductive diaphragms that exceed the maximum permissible projected area, the following methods must be applied:
  • Equipment is always used to transfer electrically conductive fluids
  • Explosive environment is prevented from entering the internal portions of the pump (i.e, dry running)

Versamatic delivers the safety of ATEX compliance in the pump styles and materials the world demands.
