Diener Precision Pumps (DPP) USA is a leading designer and manufacturer of custom precision gear and metering pumps for medical, laboratory, printing, cooling, food handling and many other crucial industries.
Diener Precision Pumps USA was born in 1994 from a passion for precision and a focus on customers’ needs. We come from a family of precision micromechanics, and today we are a part of Acrotec Group, leaders in the manufacturing of precision machined components for a variety of high-tech industries.
Diener Precision Pumps is the chosen pump manufacturing contractor for Original Equipment Manufacturers worldwide, serving them with high-precision micro gear and micro-metering pumps custom designed and engineered to suit the specific needs of their fluid management systems.
Diener Pumps USA has our design and engineering unit located in our California R&D facility, while all manufacturing is performed in Embrach, Switzerland to the highest Swiss standards for precision and quality.
At Diener Precision Pumps we don’t offer off-the-shelf solutions that you need to make effort to incorporate into your system. We manufacture tailor-made high-performance fluid pumps in medium to high volume series. Starting from scratch or from a number of basic precision metering pump and micro gear pump models, we work with your engineering teams to develop custom-made solutions that give our OEM clients exactly what they need. The customization service reduces engineering, procurement and installation costs and shortens installation times. All DPP USA pumps are manufactured to very tight tolerances to ensure consistent pump-to-pump performance. They are quiet, durable, and very compact. Sophisticated drive electronics allows quick pump responses to changing flow and pressure requirements. Each pump is 100% tested and laser-marked to guarantee traceability.
Meet the perfect precision metering pump engineered for sensitive applications in analytical, diagnostic and medical technologies.
Precise fluid mixing, simultaneous dosing and out-of-phase delivery are made possible with the innovative design of our Dual-Precision Series precision metering pump model.
The Optima Series gear pumps are ideal for any application where constant high-pressure delivery volume is required in a compact area.
The Silencer Series gear pumps were designed from scratch to be everything a gear pump should be: durable, leak-free, reliable, chemically inert and quiet.
Silencer LD Series extends the success of the Silencer Series precision gear pump to light duty applications requiring a more compact size.
The Extreme Series gear pump is designed for high stress loads. It can easily pump difficult fluids from pigmented inks to strawberry smoothies.

We start with a full analysis of your requirements and compose a clear definition of your desired pump specifications.
Our engineering team will contact you to clarify performance requirements, share technical information and CAD models, and establish project goals and timelines.
DPP US has a dedicated prototype shop where we can create or modify designs to fit your needs. We understand the need to stay on schedule, so our goal is to provide prototype sample pumps within days of receiving your inquiry.
The validation/verification step ensures that we’ve met your requirements. The continuous review of our manufacturing processes ensures that we can consistently provide the highest quality precision pumps within your budget limits.
Discover our portfolio of high-precision, high-performance and robust micro-dosing and gear pumps for various applications.
Diener precision pumps are ideal for a variety of applications in laboratory and clinical diagnostics equipment. Our gear pumps are typically used for waste and bulk fluid transfer applications, whereas our metering/dosing pumps are used where highly precise micro-dosing is required.
Diener Precision gear pumps are the ideal choice for cooling systems, whether they be water, water/glycol, di-electric, or freon-based.
Diener Precision Pumps line of “flow-thru” design pumps are ideal for food and beverage transfer and dispensing. This feature allows very quick clean-in-place flexibility and is certified to the National Sanitary Foundation (NSF/ANSI 169).
Featuring magnetically coupled drives and precision performance electronic control, Diener inkjet printer pumps ensure impeccable pulse-free ink delivery with all types of dye and solvent-based inks regardless of the printing surface.
Diener Precision gear pumps are the ideal choice for cooling systems, whether they be water, water/glycol, di-electric, or freon-based. From compact surgical laser devices to electronics and automotive systems and large data centres.
Diener pumps are the go-to solution for sterilization systems, from automated cleaning of medical equipment and surgical instruments to automated surface disinfection systems, hand sanitizer dispensers, and more.
At Diener Precision Pumps USA, we have combined the long-standing heritage of Swiss precision excellence, with the forward spirit of US design and product development to offer our clients fluid pumps of superior quality.
From pump design and engineering in Lodi, California, to production in Embrach, Switzerland and to providing support to our customers, there is only one standard we live by, to offer the very best.
Diener US micro dosing pumps use piston-driven or gear-based mechanisms to precisely move small, repeatable fluid volumes with high accuracy. Our advanced designs feature adjustable stroke volume capability, allowing for fine-tuning of flow rates and dose sizes, which makes them ideal for applications requiring minimal pulsation and precise dosing across various fluid viscosities.
Micro dosing pumps offer superior precision, reliably consistent pulsation-free flow, lower operational and maintenance costs and greater durability compared to peristaltic pumps.
Fluids with high viscosity experience greater pressure drops, increasing the risk of cavitation in systems with restrictive inlet conditions. Conversely, lower-viscosity fluids may cavitate more easily due to faster flow dynamics.
Diener pumps feature a magnetic coupling design without seals, eliminating leakage and ensuring reliable operation in medical and laboratory settings.
Diener pumps provide precise micro-dosing with self-priming and low inertia designs along with chemical inertness for consistently precise results and fast response times.
Diener pumps are constructed with chemically inert materials like stainless steel, ceramics, PEEK, and EPDM, ensuring compatibility with diverse chemicals.
