Certa Sanitary Pump From MasoSine

Certa Sanitary Pump How It Works

Sinusoidal pumping animation

The MasoSine Certa pump is a highly reliable and economical Positive Displacement Pump for food and beverage 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.
MasoSine engineers have overcome the limitations of conventional rotary lobe pumps to create one of the most efficient and reliable positive displacement pumps available.

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

Exploded View

  • Simplicity – minimal downtime. One shaft, one seal and no timing gears, enable easy in place maintenance

  • Interchangeable parts – Fully interchangeable components between pumps of the same size, reducing spares inventory

  • Self-draining and very easy to clean, with minimal downtime

  • Certa improves process efficiency and minimises total cost of ownership


Engineers in food and beverage plants are frequently faced with pumping high viscosity products ranging from frozen orange juice, deli salads and bakery produce, to cheese curd and savory pie fillings. Certa meets the highest standards in hygiene and cleanability combined with improving process efficiency and minimising total cost of ownership.

Cleaner than any lobe or circumferential piston pump

  • EHEDG Type EL - Class 1

  • All contact parts FDA and EG1935 compliant

Virtually pulse free

  • Smooth product flow, no need for ancillary dampeners

  • Up to 183.2 USGPH, 8 million cP and 217psi

Low shear handling

  • Prevents aeration foaming

  • Virtually eliminates waste of raw ingredients

Lowest cost of ownership

  • Reduced CIP cycle and reduced cleaning agents

  • Greatly reduced electricity consumption, reduced carbon footprint

Energy efficient

  • Up to 50% less power consumption than lobe or circumferential pumps

  • Higher energy efficiency at higher viscosities



Handling fruit juice concentrates with high viscosity can make pumping slow and prone to cavitation. This is especially true if the temperature drops below 0°C, at which point viscosity will make a step increase.

When viscosity increases, the maximum running speed of a lobe or circumferential piston pump needs to be reduced considerably to avoid cavitation, so reducing the achievable flow rate. Additionally, power consumption drastically increases as the rotors cut through the thicker fluid.

With Certa, changing to a higher viscosity product has negligible impact on the flow rate or power required. For example, increasing viscosity from 20,000 cP to 200,000 cP nominally increases the viscous horsepower (VHP) by around 0.1 to 0.3VHP (0.22 kW).
Lower net positive suction head requirement (NPSHR) to minimise potential for cavitation


With demand for fresh bakery products rising globally, bakers are seeking improvements in processing everything from dough and batter, to confectionery fillings and frostings. Competition is fierce and product quality becomes a vital element of sales success.

Viscosities can register in the thousands, or even millions of centipoise, often requiring costly oversizing of lobe and circumferential piston pumps to handle the high viscosity and reduce shear.
Certa’s gentle product handling capabilities and low shear conveys ingredients and mixes without degradation to improve product quality and appearance

Dairy Industry

In the cost conscious dairy sector, finding ways to reduce cleaning costs is a major challenge and one which the Certa pump easily solves. The most common method for cleaning both pumps and pipework systems employed in the dairy industry, is CIP or clean in place, using large volumes of water and a cleaning agent which is dispersed through the entire fluid handling system.

Chemicals such as sodium hydroxide, nitric acid and phosphoric acid at concentrations below 1%,are diluted in distilled water for CIP.
Pumps are some of the most difficult equipment to clean via CIP. CIP cycles often take between 20 and 40 minutes to perform, depending on the system employed. That time is non-productive and the manufacturing/processing stops while CIP is performed.
The simplicity of the new Certa pump reduces your CIP cycle and the amount of water and cleaning agents required

Handling particulates and soft solids

When inclusions such as soft fruit, diced vegetables,cooked pulses or meat are present, the Certa pumphandles these soft solids without blockages andwithout causing damage to the ingredients.


Certa delivers up to 78.9 USGPH, 8 million cP and 217psi
