The Watson-Marlow MasoSine pump is a highly reliable and economical Positive Displacement Pump for sanitary and industrial applications. Our exclusive sinusoidal rotor overcomes the limitations of conventional rotary lobe pumps to produce powerful suction with low shear, low pulsation, and gentle handling all with simple and fast maintenance and 3-A certification.

Watson-Marlow MasoSine engineers have overcome the limitations of conventional rotary lobe pumps to create one of the most efficient and reliable positive displacement pumps available.

Watson-Marlow's MasoSine exclusive single shaft and single sinusoidal rotor are the centerpieces of an innovative, simple design. With a single shaft and rotor, there is no need for the complex timing gears and multiple seals associated with conventional rotary lobe pumps. One rotor, one shaft and one seal equate to simple and economic maintenance.

Highly reliable MasoSine positive displacement pumps are the result of over 25 years of engineering innovation and product development. Customers benefit from less waste and faster processing with low shear, high suction, low pulsation, gentle handling of whole foods or highly viscous products, and simple economical cleaning and maintenance.
