Pumping Sludge, Pastes and Pulps

For example, de-watered sludge, carbon sludge, bleached earth and tomato paste are just a few examples of liquids which are acknowledged as being difficult to pump reliably and economically.

Progressing cavity pumps are acknowledged as a design of pump most suited to handling these types of liquids which is why MICHAEL SMITH ENGINEERS has recently introduced the Wangen range of progressing cavity pumps to the UK.

These compact pumps are available close coupled for duties up to 55 m3/hr at pressures up to 24 bar, while versions with bearing pedestals are suitable for duties up to 400 m3/hr at pressures to 48 bar. The extensive Wangen range includes horizontal and vertical models, hopper feed versions for viscous media with hygienic construction designs also available for food processing applications. Customised pumps can also be supplied to suit specific application requirements.

In addition to providing reliable pumping of viscous media the pumps are suitable for handling abrasive materials and also offer safe pumping of shear sensitive liquids. Other benefits include virtually pulse-free pumping, good metering characteristics, continuous displacement, low NPSH requirements and they are self-priming.

The high quality, robust and reliable design ensures low life cycle cost and they are simple to maintain on-site, resulting in reduced spare parts inventories. Thanks to their ability in transferring highly viscous and abrasive media, Wangen progressing cavity pumps are suitable for applications found in a diverse range of industries such as; water, waste water, sewage, food, dairy, beverage, brewing, pharmaceutical, cosmetic, chemical, pulp, paper, dyes, paints, petrochemical and refineries.
