Versamatic Diaphragm Pumps have no seals as the diaphragm acts as the barrier between the Liquid side and the drive side of the pump. When the liquid pressure reaches the air pressure, the Versamatic pump reaches a point of balance and stalls without the need for bypasses or overload protection.Versamatic Diaphragm Pumps pump can run dry indefinately and have the ability to self prime to 7 metres or more in some cases.

Versa-Matic's New Pump Offers Increased Air Efficiency and
Improved Performance

Versa-Matic announces the release of its revolutionary Ultra-Matic 2" high efficiency pump. A completely redesigned air section provides increased pump performance while requiring less compressed air to operate. With a pumping capacity of up to 200 gallons per minute, the Ultra-Matic provides a performance increase of up to 30% compared to other air-operated double diaphragm (AODD) pumps. "The challenge was not only to design a more efficient, high performance pump," said Nick Dorsch, President of Versa-Matic, "but also to maintain the level of dependability that customers have come to expect from our pumps. That meant integrating the innovative footprint and design features of our Elima-Matic® pump line. We're delighted that we were able to meet that challenge with the Ultra-Matic."

The Ultra-Matic's performance increase can be attributed to enhanced volumetric efficiency and the ability for compressed air to completely evacuate the pump. The redesigned air section efficiently utilizes space and eliminates friction by way of a patented sliding exhaust valve that enables air to exit directly into the atmosphere. Air flows smoothly through the valve and center section, entering through one port and exiting through another. This design results in streamlined efficiency that saves costly compressed air.

In addition, the Ultra-Matic has fewer moving parts, minimizing repair and maintenance—while a positive pressure shifting mechanism eliminates stalling. Available for Versa-Matic's 2" AODD pumps, this industry-changing breakthrough is available in a variety of materials and styles, including plastic, aluminum, cast iron, and stainless steel. The Ultra-Matic is interchangeable with all existing bolted and clamped Versa-Matic pumps, and is retrofittable with Wilden® 2" clamped-style pumps.
