Tomlinson Hall: Distribution partners sought for Liquivac
The UK-based pump manufacturers and distributors, Tomlinson Hall, is embarking on a major export campaign for their unique range of Liquivac liquid ring vacuum pumps. With almost 1,000 Liquivac pumps already in use, the company have prioritised the establishment of a global distribution network as the first step in developing overseas sales. Colin Simpson, Business Development Director, said, “To be honest, we’ve never really pushed the pumps before as they have tended to sell themselves into various niche applications.”
“However, a recent flurry of enquiries from organisations interested in the pumps’ use in desalination applications especially has convinced us to invest the resources in establishing a distribution network, commencing in the Middle East where most of these enquiries originated.”
Tomlinson Hall originally launched their Liquivac range in 1995. The pumps offer lifts of up to 8.5 metres with discharge rates of up to 30 m³/hr and discharge heads up to 3 bar. It is able to pump combinations of liquids, air, fine solids and foams. In industrial plants this ability to convey foam is particularly useful – vehicle assembly plants use the pumps within their respective machining shops to pump the foam produced by cooling liquid on high speed grinding centres to settling and filtration tanks before being re-used. The pumps are also extensively used within the nuclear industry both in the UK and in Europe, whilst marine applications include sewage, bilge and galley water extraction on both luxury cruise liners and military vessels.
One of the major application successes has been for the Sea Life Centres throughout Europe where the pumps are used to constantly draw in fresh sea water, using the beach as a natural filter, to the marine life holding tanks viewed by the public. The pumps are also suited for sump evacuation and used widely throughout the chemical and pharmaceutical process industries with single pumps often drawing from multiple sumps collecting varying materials.
However, it is the pumps’ ability to extract every drop of liquid or foam material from containers that makes it particularly useful for those industries handling high value liquids. In distilleries throughout Scotland, the canny Scottish engineers quickly learnt that being able to pull the final two or three litres of spirit out of the bottom of spirit butts could maximise yields of the precious product – in one distillery alone, just one pump achieved a pay back period of just three months before the investment was recovered. Within the distillery, the long suction lines enable one fixed pump to cater for numerous spirit containers at varying distances.
