The British Pump Manufacturers Association (BPMA), which represents the business interests of UK and Irish suppliers of liquid pumps and pump related equipment, has signed another four companies into membership.

Reliable, leak-free, low-maintenance pumping has always been essential in many process applications, particularly when ‘challenging’ liquids like corrosives need to be transferred safely and efficiently. Magnetically driven pumps are ideal for these types of duty as they have no rotating

seals to fail so the risks of downtime and lost production are minimised, as are the problems of cross contamination, or wastage of the pumped fluid.

How do you transfer liquids from drums and barrels safely and cleanly when you have no electrical or air supply available to drive the pump motor and manual, hand-operated pumps are not an option?

Transferring liquids from sumps and open tanks is often regarded as a challenging pumping application due to the presence of solids, the possibility of aeration or foaming occurring, or simply due to the aggressive nature of the liquids being pumped. The new range of Arbo sealless thermoplastic immersible centrifugal pumps are ideal for these situations where metal pumps could suffer from the effects of corrosion.

There are certain liquids, which, due to their composition, their characteristics, or how they react to process conditions (and in some situations, a combination of all three) will present challenges to achieving efficient, trouble-free pumping. Emulsions are an example of a ‘difficult’ liquid and users should be aware of the potential problems that can occur if the ‘wrong’ type of pump is specified.

A new range of hygienic internal gear pumps which provide the all-important features and benefits for pumping in food, brewing, pharmaceutical, fine chemicals and other ‘sensitive’ hygienic applications has been introduced by gear pump specialists Viking Pump.

The new range of Arbo thermoplastic mechanically sealed centrifugal pumps are available in a choice of polypropylene, polyethylene, PVDF and PTFE so they resist the effects of aggressive chemicals which can cause corrosion problems for metallic pumps.

Reliable, leak-free and low-maintenance pumping is essential (though often taken for granted) in many process applications, even when ‘challenging’ liquids like corrosives are being transferred. The Finish Thompson SP series of magnetic drive, self-priming centrifugal pumps are ideal for these situations as they provide the combination of fast, reliable and powerful performance with corrosion-resistant materials that withstand the rigours of the most demanding applications.

Transferring liquids from small drums, buckets and carboys using hand-operated, manual pumps can be a time-consuming and messy process, even if correct procedures are followed. An easier, safer and more efficient method is by using light and compact motor driven drum pumps like Finish Thompson EF Series drum pumps.

The compact and lightweight Micropump range of magnet drive pumps are now available with all-new electromagnetic brushless DC motors which provide increased torque and power for liquids handling applications requiring higher flow rates.
