Mouvex adds A55 Model to lineup, celebrates 50 years

July 22, 2015

Mouvex, part of PSG, a Dover company and a leading manufacturer of positive displacement pumps, announces the addition of the new A55 model to line of A-Series eccentric disc pumps. A55 pump models have been designed to replace existing Mouvex AR O pumps and are ideal for industrial applications involving both thin and viscous liquids.

The Mouvex A55 pump features ductile iron construction and the ability to handle differential pressures up to 10 bar (145 psi), enabling it to be used in the safe transfer of viscous, non-lubricating, volatile or delicate fluids in a variety of applications. These pumps are offered with a variety of connection types and options, including the availability of both Mouvex or standardized mechanical seals, which helps expedite installations regardless of location. A55 pumps also feature 4” suction and discharge ports and maximum flow rates up to 55 m3/h (242 gpm).

In addition, Mouvex is celebrating its 50th anniversary of manufacturing A-Series pumps in 2015. Since 1965, A-Series pumps have been manufactured, assembled and shipped from the PSG Auxerre, France facility. Over the past 50 years, A-Series pumps, of which thousands are operating worldwide, have been known for their reliability, durability and cost effectiveness, and have earned a reputation as the ideal pumping technology for some of the harshest applications in the world.

“We are extremely proud to be celebrating 50 years of manufacturing the A Series pump at Mouvex,” said Paul Cardon, Industry Product Manager for Mouvex. “Our eccentric disc pump technology has a background of over 100 years, and the A Series is one of our key product lines. For 50 years now, A Series pumps have proven their reliability and performance in a variety of tough applications. By introducing new pump models like the A6 and A55, we are expanding the capabilities of the A Series pump line, allowing them to serve more markets and a wider range of industrial applications.”

A Series pumps are positive displacement pumps that utilize eccentric disc technology, which enables self-priming and run-dry capabilities while maintaining a constant flow rate regardless of changes in viscosity and pressure. These pumps also maintain their initial performance over time and are ATEX-certified for use in potentially dangerous environments with the ability to run-dry for up to six minutes. Available in seven different sizes--AZ, AD, A6, A12, A18, A31, and A55--Mouvex A-Series pumps have maximum speeds to 600 rpm, can handle temperatures up to 150° C (302° F), as well as suction and discharge ports from 1 ½” through 4” in size.
