Energy Efficiency Prompts Creamery To Invest In Second MasoSine Pump

When a world-famous creamery from Cornwall installed a new depositing machine at its factory, the company’s previous success with a MasoSine pump from Watson-Marlow Fluid Technology Group (WMFTG) ensured it returned to the same source for a second unit. This time around, an energy-efficient Certa 100 was recommended to transfer a range of double and single cream products from mobile storage tanks to the hopper of the new depositing machine.

A E Rodda and Son has been making Cornish clotted cream since 1890, when Eliza Jane Rodda, Great-Great Grandmother of the current Managing Director, Nicholas Rodda, started making Cornish clotted cream in her farmhouse kitchen here in the heart of Cornwall. 128 years later, the company still maintains many traditional methods of manufacturing. Rodda’s led the way in campaigning to get protected status for this Cornish delicacy and in 1998 it was awarded Protected Designation of Origin status, along with the likes of Champagne and Parma ham.

The company is the largest Cornish clotted cream Brand in the U.K. Rodda’s also exports its products around the world with its famous clotted cream being served alongside cream teas on a number of airlines.

Previous success

In 2012, Rodda’s installed a MasoSine SPS 200 sine pump as part of a new clotted cream line, and its reliable performance has impressed the maintenance team.

“We were in the process of investing in a new depositing machine, which essentially deposits cream into a pot and seals it with a lid, so we needed to look for a suitable pump to transfer the product from mobile storage tanks,” explains Maintenance Supervisor Paul Johnson.

“Over the past six years of hard work we’ve had virtually no maintenance issues with the SPS 200; it has basically looked after itself,” states Mr Johnson. “Importantly, the pump does not damage or compromise product integrity, which is crucial to our production process.”

This same approach was needed for the company’s new pouring cream production facility: low shear, low pulsation and gentle handling.

“Using a centrifugal pump, for example, would effectively churn the cream into something like butter,” says Mr Johnson. “A sine pump was clearly the way forward and we were keen on the new Certa from WMFTG, especially because of its energy-efficiency attributes.”

Unlike traditional pumps with rotors that cut through the fluid, Certa’s sinusoidal rotor gently carries product through the pump to dramatically reduce shear, while cutting power consumption by up to 50% with high-viscosity fluids. Further advantages and high-performance levels delivered by sinusoidal technology include virtually no pulsation, simplicity, reliability, interchangeable parts and low cost of ownership.

Straightforward cleaning

Watson-Marlow’s technical team advised A E Rodda and Son that the smallest pump in the Certa range, the Certa 100, would meet their requirements. This pump delivers the required flow rate of up 4200 l/h.

In terms of the process, a mobile storage tank is wheeled up to the new depositing machine, where upon the Certa 100 transfers cream from one to the other. The pump is mounted low, facilitating a head of two metres into the machine’s hopper. No priming is required.

Offering EHEDG (Type EL Class I and EL Aseptic Class I) and 3A certification as standard, Certa is extremely easy to clean for minimal downtime. Cleaner than any lobe or circumferential piston pump, a range of seven Certa pumps is available for flow rates up to 99,000 l/h and pressures to 15 bar.

“We’ve had the MasoSine Certa 100 for around 12 months and there have been no issues whatsoever,” reports Mr Johnson. “Moreover, the pump is impressively quiet and is extremely energy efficient. From experience we have learnt that it is three times more expensive to run a pneumatic pump than an electric pump.”
