Product Datasheet Gear Pump: Silencer Series – 1500ml / min – BLDC Motor & Integrated Motor Control 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.
