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 constructionself-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

Benefit Icon

Chemically Resistant

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. 

Benefit Icon

Long Life

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. 

Benefit Icon

Low Noise

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) 
    • PTFE 
    • ETFE
    • PVDF 
    • PEEK

    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 hato 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.
