Pump Engineering has announced that the Ponndorf PK40 compact double-head hose pump is now available. The Ponndorf PK40 high-pressure twin unit is capable of providing flows up to 15,000 litres/hr at pressures up to 15 bar. The versatile, self-priming, pumps offer the advantages of peristaltic pumping, which are particularly relevant to the food-processing and water-treatment industries. For example, shear-sensitive, delicate liquids or those containing solids remain unaffected by the pumping process. The absence of seals, glands and valves reduces the likelihood of component failure and resulting downtime, sometimes associated with demanding pumping applications, such as those involving abrasives and other similar aggressive media. Cleaning and washing is also simplified because only the hose has contact with the process fluid, therefore quick and effective cleaning is achieved simply by flushing through the hose. The pump is fully reversible and is supplied with a selection of hose ...

There are now more variations of cable gland available than ever, and with more choice comes the requirement for more knowledge in order to make the right selection. Considerations such as suitability for purpose, sealing, safety and installation time all need to be balanced against cost, which is always an issue.

With a huge range of fast new push-fit designs, tighter regulations and new materials coming onto the market it is essential to look at what is fit-for-purpose. Essential criteria include the quality of the hole available for the cable entry, the thickness of the cable, the ingress protection required (IP ...
