Sine pumps from Watson-Marlow Bredel were supplied to a food processing equipment specialist to replace rotary lobe pumps in a challenging mashed potato transfer application.
MasoSine, a division of the Watson-Marlow Pumps Group has supplied several MasoSine SPS 2.5 pumps to DC Norris & Co Ltd. The pumps replaced rotary lobe pumps in a challenging mashed potato transfer duty after the latter could not provide enough suction to cope with high viscosity levels.
DC Norris is an established supplier of food processing equipment. Following extensive trials with a major customer for the supply of turnkey food plants across Russia, the company encountered a pumping problem with mashed potato.
The company’s Business Development Manager, David George explained that a 2-tonne per hour mashed potato system was to be installed at each plant with a high percentage of the finished product being bagged for cook/chill ready meal applications.
DC Norris’ standard pump/fill station used a rotary lobe pump that could not provide enough suction to prime the pump.
Having used MasoSine pumps previously for other viscous pumping duties, DC Norris decided to replace their lobe pumps with the MasoSine SPS 2.5 sine pumps ideally suited to high pressure, hygienic operations in the food manufacturing sector.
The pump’s exclusive sinusoidal rotor overcomes the limitations of conventional rotary lobe pumps to produce powerful suction with low shear, low pulsation and gentle handling.
Mr George states that the MasoSine pump resolved their problem across the range of viscosities that can be experienced with mashed potato.
