- Progressive cavity pumps fail to perform sufficiently when pumping 250,000 cP viscosity peanut butter
- Requirement for 5 tonnes of peanut butter pumped from grinder to holding tank daily
- Pump downtime and maintenance costs reduced by switching to MasoSine SPS200
Faced with a failing progressive cavity pump when trying to transfer peanut butter from the grinder to a holding tank, a reputable food plant in Pretoria, South Africa, has found a far more reliable and cost effective solution in a MasoSine SPS200 process pump from Watson-Marlow Fluid Technology Group.
The peanut butter manufacturer was advised to consider MasoSine technology by the grinder manufacturer, and a SPS200 was duly installed in April 2014. The pump was immediately set to work pumping 250,000 cP viscosity peanut butter at a rate of 1000 l/hr (85C, against ±9 bar).
Product integrity assured
Selected, among numerous other factors, for its viscous pumping ability, the MasoSine SPS200 features a unique sinusoidal rotor that delivers a lower shear, gentle pumping action that safely transfers delicate products without risk of degradation.
This is in contrast to the PC pump deployed previously, which battled to pump the high viscosity of peanut butter. Furthermore, dry running due to inconsistent feed between the grinder and the hopper would lead to reduced suction.
MasoSine SPS pumps are suitable for a multitude of applications up to 15 bar pressure and 99,000 l/hr flow rate. Importantly, products with viscosities up to 8 million cP can be transferred with powerful suction.
With this in mind, SPS pumps are able to deliver a constant feed of whole foods, meats, confectionary, dairy products and concentrates. Capable of handling soft solids up to 60mm, MasoSine pumps achieve high product quality and improved yield rates for food processing customers.
More uptime, fewer costs
To date, the Pretoria peanut butter plant reports that the MasoSine SPS200 has been pumping successfully with minimum downtime. In fact, the pump has offered considerable savings over the maintenance costs encountered previously with the progressive cavity pump. This is due to the pump’s simple design, with one shaft, one rotor, one seal and no timing gears.
The upshot is that maintenance and cleaning of the SPS200 takes just minutes and can be performed in-situ by a line operative (or by a CIP process, if required). Conversely, due to the design of the PC pump, maintenance took longer than the MasoSine technology and was also more expensive, leading to unacceptable levels of downtime.
The SPS200 now runs intermittently to pump circa 5 tons of peanut butter to the holding tank every day.

About us
Watson-Marlow Fluid Technology Group (WMFTG) peristaltic tube and hose pumps meet requirements including: value for money; low cost of ownership; reliability and ease of maintenance to the food and beverage, chemical, pharmaceutical, mining and many other industries.
We demonstrate how pumps deliver significant process efficiencies over the lifetime of the equipment. Whether performing flavouring addition in food processing, chemical metering in water treatment or mineral recovery, we have a solution which can cut pump downtime and reduce costs through higher accuracy metering and transfer. WMFTG has dedicated application engineers available to help customers make the right pump and tubing choice from a range providing microlitres per minute to 80 cubic metres per hour flow rates.
The only part of the pump to come into contact with the product is the tube or hose. This means there are no seals or valves that can wear or fail. Replacing the tube or hose can be performed quickly and safely. Peristaltic pump benefits include:
Total fluid containment with no seals No ancillaries Handle viscous and abrasive slurries and sludge Self-priming capability Dry running without damage to the pump In addition to their range of positive displacement pumps, Watson-Marlow Fluid Technology Group has added PTFE-lined chemical and industrial hoses to their range. Aflex hoses are reinforced to withstand the most severe conditions and use.
