International vacuum pump manufacturer and supplier Busch Vacuum is actively rebranding its petrochemical pump offering in South Africa and internationally.
This exercise follows Busch Holdings’ acquisition of liquid-ring pump manufacturer Graham Vacuum, a subsidiary of the Graham Corporation in the US.
“The products that became part of the Busch Vacuum product offering, owing to the acquisition of Graham Vacuum, are still viewed as Graham products, despite the fact that Graham Vacuum was acquired in 2005. “Busch Vacuum, therefore, is taking every business opportunity to associate its own name with each of its products,” says Busch Vacuum South Africa MD Joe Jagger.
Graham Vacuum was acquired to increase Busch Vacuum’s petrochemical offering in its product port- folio. Graham Vacuum offered liquid-ring vacuum pumps in special alloys for the petrochemicals industry.
Busch Vacuum had always offered a limited range of pumping solutions for petrochemical applications, offering dry vacuum pumps to the market. However, it was not offering a widely sought-after product, says Jagger.
The petrochemical pump market is growing steadily and liquid-ring vacuum pumps are one of the most widely used in petrochemical applications, explains Jagger.
The acquisition of Graham Vacuum and its liquid-ring vacuum pump knowledge greatly complemented Busch Vacuum’s experience in dry vacuum pump applications and increased the company’s exposure to the petrochemicals industry, he adds.
Busch Vacuum chose to acquire liquid-ring technology rather than develop it, as the technology is one of the oldest pumping processes used in petrochemical vacuum applications.
Liquid forms a ring within a liquid-ring pump and through an exhaust process creates a vacuum. The liquid medium can be water, petrol, paraffin or glycol, depending on the volume that is being pumped.
Another advantage of the acquisition is that it enables Busch Vacuum to offer Aetex- approved liquid-ring vacuum pumps to the petrochemicals market.
Aetex is a European certification that South African chemical companies are beginning to recognise, which measures the explosion resist-ance of a pump for chemi- cal and petrochemical processing. It is an alternative to the US standard that is used in South Africa; however, it is more stringent, says Jagger.
South Africa is becoming more sensitive to explosion classifications in its petro- chemicals industries. To compete internationally, products must meet inter- national standards and South Africa is becoming more disciplined in this regard, explains Jagger.
Liquid-ring vacuum pumps form part of the 74% of Busch Vacuum South Africa’s pro-duct offering that meets Aetex standards. The company’s range of dry vacuum pumps for petrochemical dry processing applications is also Aetex approved, he adds.
Busch is negotiating an order with chemicals, rubber and plastics manufacturer Lamex Chemicals. Lamex is ensuring that it complies with Aetex standards.
Busch Vacuum South Africa expects that the petrochemicals market will require a large order of pumps manufactured from materials such as stainless steel for liquid-ring vacuum pumps, as well as bronze and stainless impellers.
Busch Vacuum South Africa is the distributor for Africa. It is currently supporting installations in Angola and Nigeria. The company will be invest- ing in a Cape Town office before June, and will be in Durban by August.
