AHC galvanises its pump operations

AHC Benelux, specialist in the provision of surface treatment technologies for engineering applications, has installed a closecoupled peristaltic pump from Watson-Marlow Pumps Group to help process aggressive wastewater fluids produced by various plating and galvanising processes.

A Watson-Marlow baseplate pump was installed many years ago.

When it came to the end of its natural life, AHC returned to Watson- Marlow for another - this time a Series 521F/REC close coupled pump.

Featuring high performance engineered plastics and a stainless steel pumphead, easy set-up and maintenance are key features of this peristaltic pump. Its high resistance to chemical attack makes it rugged enough for harsh environments, delivering cost-effective, precise pumping and a long service life.

"We installed the 521F/REC pump fitted with Marprene thermoplastic tubing elements in February 2010 and it has since performed extremely well," says Luc Heldens, supervisor chemicals and R&M at AHC. "It's pumping hydrochloric acid for about 1h/day and caustic for about 15h/day.

The pump is linked integrally to our pH controller and we've had no issues whatsoever with reliability."
