Beating about the Busch

Busch (UK) has supplied a crypton coasted ATEX certified dry pump to Robinson Brothers, a leading speciality chemicals manufacturer, based in West Bromwich, West Midlands.

One of the Busch's ND.0160.A Cobra pumps with special crypton coating, which is resistant to aggressive chemicals has been installed as part of Phase I of a new manufacturing facility at Robinson Brothers, and will work in conjunction with a 'Hastelloy' filter dryer. The processes involve methanol, isopropanol, toluene, acetic acid and traces of hydrochloric acid. This was identified as a difficult cocktail, which required a specialist vacuum pump to prevent corrosion, while still conforming with the relevant atex standards.

Tony Quinney, site engineer manager, Robinson Brothers, said: 'we have worked with Busch for around ten years now. We are impressed with their ongoing product development programme, particularly concerning the new internal coatings, which give much more resistance to corrosion and help keep maintenance requirements to a minimum.'

The Cobra is described by Busch as being economical due to its low energy consumption, as well as having state of the art design conforming to category 1 directive 94/9/EG (ATEX 100a). The pump is available with various sealing options to suit the individual needs of the customer.

Robinson Brothers is one of the UK's largest independent manufacturers of speciality organic intermediates. Its products are used in pharmaceuticals, agrochemicals, rubber products (Robac), food and beverage products and cosmetics, and speciality polymer chemicals.
