Cost Effective and Efficient Sludge Cake Pump
Moving increasingly dry dewatered, sewage sludge cake efficiently and cost-effectively is a problem for many sewage treatment works.

The onset of AMP3 means that greater screening efficiencies will be required for aesthetic pollutants such as faeces, tissue paper and sanitary products, as Robbins and Myers explains
For efficient, cost effective sanitary pumping, this economical, high performance, low maintenance pump is ideal for a wide range of process applications.
Unlike other pumps, the progressing cavity pump is free from valves, which may clog or stick when pumping thick liquids, and timing gear adjustments are not required.
So time and effort is saved from the start.
The self priming pump delivers a steady non-pulsating flow, ideal for batching processes and can handle solids up to 25 mm in diameter.
Design options include flange and open throat models as well as bare shaft and close-coupled configurations.
Providing uncompromising quality, reliability and application versatility, R and M Sanitary pumps can cost effectively handle thin liquids like soups and juices.
It offers minimal product degradation in shear sensitive applications like salad dressings and salsas.
More viscous slurries such as peanut butter or jam are moved efficiently.
Products like diced fruits and vegetables are moved with minimal damage.
For abrasive applications, like toothpaste, the sanitary pump gives long service.
It can also consistently handle entrained gases in yogurt and yeast, for instance at pressures of up to 54 bar.
A hopper feed system is also available for fluids that are not free flowing such as dough and sausage meat.
The key components in a progressing cavity pump are the rotor, which is a single external helix, machined from high strength carbon steel or stainless steel, which moves round within the stator - a double internal helix moulded of a choice of tough, abrasion resistant elastomers, permanently bonded within an alloy steel tube.
As the rotor moves within the stator, cavities are formed which progress from the suction end of the pump to the discharge end, gently conveying the pumped material.
The shape of the rotor within the stator helix ensures a continuous seal at all times and keeps the material flowing steadily at a fixed flow rate.
