Peristaltic pump technology from Watson-Marlow Pumps has helped Portishead Press, a specialist print media company based in Bristol, to eradicate issues with printing machine breakdowns caused by failures to its previous air-operated diaphragm pump.

Portishead Press offers both digital and litho printed communications and supplies everything from brochures and newsletters to corporate stationery.

The company had been experiencing a problem with its five-colour printing machine, which, until recently, was using an air-operated diaphragm (AOD) pump to keep coatings flowing around the system.

The styrene acrylic polymer coatings were leaking into the machine’s bearings when the seals on the AOD pump perished; the bearings would seize, causing the printing machine to stop.

With Watson-Marlow’s 621VIX/RE close-coupled peristaltic pump technology, nothing but the tube touches the fluid, eliminating the risk of the pump contaminating the fluid or vice versa.

Key benefits of product application

  • Peristaltic pumps have reduced the need for maintenance.
  • The technology is able to move the coating fluid quickly, without introducing air.
  • The 621 series peristaltic pump provides gentle, low-shear fluid handling, thus avoiding air entrainment.
  • In addition, the issue of frothing has been circumvented.
