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.”
