Model Certa - Pumps



Superior viscous handling. EHEDG Type EL - Class 1. Up to 50% less power than other pumps. Low shear and virtually no pulsation.

Certa is latest innovation from MasoSine Process Pumps, the creators of Sine® pump technology.

Its launch sets even higher pumping standards in food, beverage and cosmetics processing. Offering EHEDG (Type EL Class I) and 3A certification as standard, Certa is extremely easy to clean for minimal maintenance and downtime.

  • Cleaner than any lobe or circumferential piston pump
  • Virtually pulse free
  • Low shear handling
  • Lowest cost of ownership
  • Energy efficient

This advanced new innovation in food pump technology not only delivers high suction capability to handle viscous products, it offers significant advantages over alternative technologies. Unlike traditional pumps with rotors that cut through the fluid, Certa’s sinusoidal rotor gently carries fluid through the pump to dramatically reduce shear, while cutting power consumption by up to 50% with high viscosity fluids.

The typical advantages and high performance levels delivered by proven MasoSine sinusoidal technology include virtually no pulsation, superior viscous handling, simplicity, reliability, energy efficiency, interchangeable parts and low cost of ownership.

For many years, Sine® pumps have played an important and highly successful part in conveying fluids with viscosities of up to 8 million cP. The new Certa pump now completes the existing product range by offering users a fully CIP capable pump at flow rates up to 99,000 l/hr.

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 savoury 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 41,610 l/h, 8 million cP and 15 bar

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 pump handles these soft solids without blockages and without causing damage to the ingredients.
