Gear Pump: Silencer Series – 500ml/min – BLDC Motor
Diener Precision Pumps is certied to medical standard ISO 9001 / ISO 13485. In addition, we have a clean-room according to ISO Class 7.
All DPP pumps are customized to suit your requirements: the information below represents one of the possibilities.

Features
The Silencer series is everything a gear pump should be: simple, leak-free,
chemically inert, reliable, and economical. It’s manifold mounting simplies
the plumbing and reduces the installed cost in your system. A magnetic coupling
ensures the pump will never leak and wetted materials are chosen to withstand
a wide range of aggressive chemicals. The enhanced gears and shaft bearings
have been optimized to ensure a long, trouble-free life and very low power
consumption. And of course we manufacture every component using Diener’s
superior production techniques, resulting in a very high quality product at a
relatively low cost.
