MasoSine SPS Pump

MasoSine SPS Series: High Pressure Sanitary & Industrial Pumps


Whether installing in a new plant or seeking to replace an existing pump, MasoSine SPS pumps offer the ideal solution to improve your performance and minimise cost of ownership.

The sinusoidal rotor design of MasoSine SPS pumps delivers a lower shear, gentle pumping action that safely transfers delicate products without risk of degradation.

SPS pumps are suitable for industrial applications up to 217psi (15 bar) pressure at flows up to 434 GPM (99,000 l/hr). Products with viscosities from 1cP to 8 million cP can be transfered with powerful suction up to 0.85bar.

Capable of handling soft solids safely up to 60mm, maintaining end product quality and delivering high yield rates.

MasoSine EcoSine Pump

MasoSine EcoSine Series: Sanitary & Industrial Positive Displacement Pumps


MasoSine's EcoSine pump satisfies demanding processing requirements cost-effectively, using the unique MasoSine pumping principle. This model is a sanitary pump for pressures to 6bar (90 psi)and bi-directional operation.

The sine-wave-shaped rotor creates four moving chambers which gently convey the duty fluid from the inlet port to the higher-pressure discharge port. The gate prevents any fluid passing back from the discharge side to the lower-pressure suction side of the pump.

Ecosine is for sanitary duties requiring strong suction/low shear.

  • Capacity: 125,000 litre/hour (550 US gpm)
  • Pressures to 6 bar (90 psi)

Typical applications: dairy, prepared ...

MasoSine MR Pump

MasoSine MR Series: Low Shear Sanitary Pumps


High-Temperature Pumping

The MasoSine MR’s heat-retaining (or heat-excluding) jacket allows the pump to reach the duty fluid temperature rapidly, and stay there. A heat-retaining front cover is available. This model is for high-throughput sanitary pumps up to 150 psi pressure.

Seal Systems

MasoSine pumps have one shaft and therefore one seal, unlike regular two-shaft rotary lobe pumps that require two seals. The standard seal is a triple lipseal design, which is ideal for most food and beverage applications. Mechanical seal systems are available on request for applications where CIP is a requirement.


MasoSine pumps are supplied as standard with ...
