Watson-Marlow Masosine Technology Replaces Gear Pumps at Chocolate Factory

Pumping chocolate confectionary

Watson-Marlow Masosine MR and SPS series positive displacement pumps have been installed at the Fakenham, Norfolk plant of chocolate and confectionary specialist, Kinnerton. The first Masosine pump was introduced to replace a gear pump that was damaging product on an Easter egg production line, with a second model acquired recently to support a newly installed caramel production line. The company has now decided to standardise on Masosine pumps moving forward.

“We had an inclusion mixer on one particular line that was supported by an ageing gear pump,” says the company’s engineering supervisor, Phil Barwick. “The line was set up to produce a new white chocolate Easter egg with dried raspberry mixed in. However, when the fruit first went through the mixer, it was squashed by the gear pump – in effect producing ‘pink’ chocolate Easter eggs.”

With Easter one of the company’s peak production periods, a quick fire solution was needed. Fortunately a recent trade show attended by Kinnerton demonstrated the merits of Watson-Marlow Masosine positive displacement pumps and the company duly requested the trial of an MR125 model.

“It was immediately apparent that it ticked all of our boxes,” says Mr Barwick. “Not only did it not damage the product – even subsequently introduced biscuit pieces were damage-free – it was also exceptionally easy to maintain and clean.”

The MR series is a range of medium duty sanitary pumps offering flow rates up to 91,000 litres per hour and pressures up to 10.3 bar. Typical applications include chocolate, cheese, curd, yogurt, concentrates, yeast, batter and stews.

Kinnerton also have three Watson-Marlow Masosine SPS 2 sanitary/industrial pumps. With a capacity up to 4m³ per hour and pressures up to 15 bar, the SPS is ideal for viscous applications such as caramel,gelatine and glucose, as well as industrial products such silicones, adhesives and polymers.
