Rodda’s smooths clotted cream with sine wave pump 27 September 2013

Cornish creamery Rodda's – which installed a new clotted cream line last year, in time for the Christmas rush – is reporting success with a MasoSine SPS2 sanitary process pump.

Engineering supervisor Paul Johnson says the pump, supplied by Watson-Marlow, is ideal for the job, because of its high-flow, yet gentle handling characteristics.

"Clearly, we are keen to avoid any product damage or compromise to product integrity – using a centrifugal pump, for example, would effectively turn the cream into butter," states Johnson.

"This isn't a high-pressure application, rather a high volume one. Essentially, the pump transfers liquid cream from a tank to a hopper on a new production line. The machine then fills our range of pots," he explains.

High flow is achieved using the pump's sine-wave shaped rotor, which creates four moving chambers that convey the duty fluid from the inlet port to the discharge port. The scraper gate prevents any fluid passing back from the discharge side to the suction side.

Johnson explains that Rodda's operate its MasoSine SPS with a variable speed drive and ultrasonic level sensors in the hopper. If the level is high, the pump runs slower, and vice versa.

"At the time, because of the need to meet pre-Christmas demand, Watson-Marlow helped us out with the immediate delivery of a demo pump. It was a manual version of the pump we have now, and it got us through this busy period."
