Gear Pump: Optima Series – 1000ml/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 Optima series is designed for applications requiring accurate ow
in a very small package size. The wetted materials and gear construction are the same as those of it’s larger cousins, but by removing one
of the shaft bearings the overall length is much shorter. In addition, the
magnetic coupling has been miniaturized to further reduce the overall
length without sacricing highpressure performance. The inlet and
outlet port locations can be located on the side, top, or end of the pump,
and are available in a variety of sizes. The brush-less DC motor has an
integral ange allowing bulkhead mounting, and its IP55 rating ensures
it will stand up to harsh environments.
