Watson-Marlow's MasoSine SPS200 Makes Pumping Peanut Butter Easy
Watson-Marlow is a world leader in peristaltic pumps and associated fluid path technologies. The pump company recently provided a solution to a food plant in Pretoria, South Africa that was trying to pump peanut butter. The food plant’s existing progressive cavity pump was failing when trying to transfer peanut butter from the grinder to the holding tank. The MasoSine SPS200 was installed in April, 2014 and began pumping 250,000 cP viscosity peanut butter at a rate of 1000 l/hr immediately. It now runs intermittently to pump about 5 tons of peanut butter to a holding tank every day.
There are many features that set the MasoSine SPS200 apart from other pumps. It features a unique sinusoidal rotor that can safely transfer delicate products without degradation. This pump was a big improvement for the food plant in Pretoria, South Africa. Their previous pump fought hard to process the high viscosity of peanut butter and prevent dry running, which led to reduced suction because of the inconsistent feed between the grinder and the hopper.
The pumps can handle up to 15 bar pressure and a 99,000 l/hr flow rate. Even viscosities up to 8 million cP can be transferred easily. The new cavity pump can deliver a constant feed of soft solids that include whole foods, meats, dairy products, and more of up to 60mm, which can drastically improve yield rates for food processing customers.
The Pretoria peanut butter plant continues to use the MasoSine SPS200 because it is able to operate with minimal downtime. The pump has even offered considerable maintenance savings compared to the previous cavity pump, thanks to the pump’s simple design that includes one shaft, one rotor, one seal, and no timing gears. Maintenance and cleaning takes just minutes and can be performed in-situ by a line operative, or by a CIP process. Maintenance on the previous pump took much longer, was more expensive, and led to unacceptable levels of downtime that are no longer an issue with the new pump.
