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. |
