MasoSine's 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.

Maintenance takes minutes and can be performed in-place by a line operative. Replace off-the-shelf wear components to restore to “new pump” performance.

A single sinusoidal rotor creates four evenly sized chambers as it rotates
Fluid is “pulled” through the inlet into each chamber in turn
The chamber rotates, contracts, closes then discharges fluid through the outlet port
The opposite chamber opens to draw in more fluid, resulting in a smooth flow with virtually no pulsation
A gate functions as a seal between the inlet and outlet of the pump, preventing fluid escaping
Simple maintenance performed in place by a line operative
Bi-directional running enables duty fluid to be returned to source
Separation between the wet end and dry end ensures no contamination
