Watson-Marlow, a world-leading positive displacement pump manufacturer, has acquired the German MASO / sine pump manufacturing business from MASO Process-Pumpen and Sundyne Corporation. The MASO / sine pump products will now be branded MasoSine.

The purchase demonstrates the Watson-Marlow Pumps Group’s continuing commitment to leadership and innovation in positive displacement pump technology.

MasoSine is a natural extension of the Watson-Marlow peristaltic pump range, complementing its offering in sanitary markets, and joining a portfolio comprising Watson-Marlow Pumps, Watson-Marlow Tubing, Bredel Hose Pumps, Alitea OEM Pumps and Flexicon Filling Systems.

MasoSine positive displacement pumps are the result of over 25 years of engineering innovation and product development. The pump is highly reliable and economical for sanitary and industrial applications. Its exclusive single shaft and sinusoidal rotor overcomes the limitations of conventional rotary lobe pumps to produce a powerful suction with low shear, low pulsation, and gentle handling. One rotor, one shaft and one seal equate to simple and economic maintenance.

The technical fit between MasoSine and Watson-Marlow pumps is excellent, and the wavelike action of the sinusoidal rotor can be visualised as a stainless-steel peristaltic pump.

Mike Sullivan, marketing manager of the Watson-Marlow Pumps Group, comments: “The strategic acquisition of MasoSine further broadens our product range and strengthens Watson-Marlow’s position in the positive displacement pump market. This is yet another exciting milestone for Watson-Marlow and we are looking forward to accelerating our growth within the food and pharmaceutical market with our broadened product portfolio coupled to our process expertise.”

Manufacture, design, and product management of MasoSine will continue to be based in Ilsfeld, Germany. The UK and US-based MasoSine sales teams have joined Watson-Marlow from Sundyne and will also continue to work uninterrupted in their current roles.
