Precision Pumps for Laboratory and Clinical Diagnostics
Waste and Bulk Transfer vs. Micro Dosing
Diagnostic and Medical equipment covers a wide range of products and Diener Precision Pumps are ideal for all of them. Our precision gear pumps are typically used for waste and bulk fluid transfer applications, whereas our metering/dosing pumps are used where ultra-low (micro-dosing) is required.
Build from the Ground-up for Chemically Harsh Environments
The advantages of a Diener pump include inert materials of construction, self-priming, delivers high pressures/flows, and are very compact.
The Power Behind the Pump
Precise electronic flow control, tachometer feedback, and over-current protection features are standard on all versions and ensure safe, reliable operation.
Why DPP lab pumps are the preferred choice for laboratory and medical diagnostic technology
Our pumps are made from materials that are resistant to a wide range of aggressive chemicals. This means our pumps can also operate reliably and precisely in the harshest environments.
DPP pumps are all characterized by their robustness and performance. Wear and tear is at its lowest, and their smart designs ensure a sustainable reduction of operating costs.
Thanks to intelligent design and selected components, our pumps are some of the quietest of their kind. This makes them unbeatable when it‘s important to have peace and quiet.
Chemically Inert Pumps
Reactive wetted materials can render certain chemicals unstable. Diener Precision Pumps are constructed of inert materials and include:
- Ceramic (alumina)
Our gear pumps are made of 316L stainless steel, PEEK, and a variety of o-ring material options.

Case Study – Ratio Metering Challenge
The customer wanted to accurately mix a concentrated base solution with water. The volumetric ratio had to be within 0.5 µL per stroke. Using two pumps was expensive and presented electronic control challenges.
Diener’s adjustable metering pumps can be calibrated at precise dispense volumes, so it made sense to mount one to each end of double-ended stepper motor. The pumps operate together and are calibrated to the exact volumetric ratio, in this case 1 part buffer to 10 parts water. By using different piston diameters, we were able to fulfill other mixing ratios up to 100:1 using the same basic pump design.
