Busch's Crypton Solution

Busch (UK) Ltd has supplied a crypton coated ATEX certified dry vacuum pump to a leading speciality chemicals manufacturer.

One of the company’s ND.0160.A Cobra pumps with special crypton coating, which is resistant to aggressive chemicals, has been installed at Robinson Brothers' factory in West Bromwich in the West Midlands.

The vacuum pump was installed as part of Phase 1 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 hydochloric 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 engineering manager for Robinson Brothers, said: "We have worked with Busch for around 10 years now. We have looked at other vacuum pump manufacturers, but have always specified Busch products for our process needs as they give good performance and are reliable.

"We are also impressed with the ongoing product development programme at Busch, 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.
