Certa Pumps Eradicate Yeast Handling Issues at Brewery

Posted on by Sara Springer

Certa Sine pumps from Watson-Marlow Fluid Technology Group (WMFTG) have replaced rotary lobe pumps at a brewery in Germany, eliminating gassing issues and boosting pump efficiency.

In the brewing process, once fermentation is complete, the yeast is recovered (or harvested) for re-use. However, much of this yeast settles at the bottom of the fermentation tank where it can set into compacted bulk so pumps with high suction capabilities are required to draw the solid yeast from the tank.

Certa Brewery YeastGas Locking

Yeast naturally forms bubbles during fermentation and can cause gassing-off (gas locking) issues for the pumps used to harvest it. Gas locking had serious and ongoing effects for the lobe pumps at the brewery, including a reduction in flow rate. This effect was particularly noticeable due to the need for long suction lines between multiple yeast tanks and the pump station.

To overcome these challenges, the brewery invited WMFTG to assess the application and make its recommendations. Several stipulations were involved, including the requirement to handle various yeast viscosities, the need for self-priming, and no gas locking. With these thoughts in mind, the brewery was advised to adopt a Maso-Sine Certa 200 series pump.

Certa offers both high suction capability and high flow. This performance level is consistent even with different yeast strains/viscosities and pipework runs. In fact, even compacted yeast is easily drawn from the fermentation vessel.

Controlled process

Certa pumping technology is virtually pulse-free, providing consistent flows despite varying product and system conditions, thus facilitating controlled yeast transfer. Due to the continuous and smooth pumping action, the pump draws the yeast from the bottom of the tank and avoids any turbulence that would cause the beer to mix with the settled yeast. This clarity enables the brewmaster to recognize immediately when the yeast removal process is complete and can stop the pump before losing beer.

A further advantage of Certa technology is low-shear pumping. The presence of high shear can lead to poor quality beer, as well as high yeast usage and costs – issues avoided with the use of Certa pumps.

It was a combination of these factors that prompted the brewery to install Certa 200 pumps, which duly led to successful and continuous yeast harvesting. The brew-master has since stated that ease of maintenance by the brewery’s personnel, and rapid CIP cleaning, are added advantages. Here, the simplicity of the Certa pumps reduces CIP cycles and the amount of water and cleaning agents required.

Certa COP Options from MasoSine

Posted on by Sara Springer

Certa Pumps were designed for CIP (Clean-In-Place) operations, yet their design works so well for difficult transfer applications that many are being used in COP (Cleaning Out of Place) systems. However, using a Certa pump in COP applications can cause problems due to the design.

Seals can be dropped and break. The special tool for removing the locking screw can slip out of the screw quickly wearing down the surfaces and “stripping” the screw or tool. The nuts for the front housing cover take time to remove, especially when breaking the pump down multiple times a day.

Certa COP Options

In order to improve performance and reduce downtime for cleaning and maintenance in this area, MasoSine is offering several optional components for easier disassembly/assembly.


  • Clean Out of Place, COP, options to enable manual cleaning with your Certa Pump
  • Simplified pump design perfect for frequent disassembly and assembly
  • Retain all the benefits of Certa such as gentle product handling, ease of maintenance, high suction capability, and flexibility
