Pump Engineering and Prototyping

Diener Precision Pumps specializes in pump engineering to meet your OEM pump requirements. Designing and manufacturing pumps is what we do. Starting with standard gear and piston sizes, we design, build, test, and refine. The end result is a pump that performs to your exact specification.

Diener Pump Engineering and Pump Prototyping

As a long term pump manufacturer, we understand the importance of quick time-to-market, so we have our own prototype shop capable of creating prototypes days after initial contact. Our fluids lab contains state-of-the-art test equipment that enable testing across a wide range of environmental conditions. We design our own endurance test rigs to perform accelerated life tests and product reliability validation.

At DPP’s California R&D facility, we continuously design and test new concepts, materials, electronics, and systems. Innovative design features assure long pump life and low installed cost.

Here is a range of different custom-fitted pump pistons sizes for metering pumps and different gears for gear pumps:

As your project moves through your prototype phase, Diener’s engineers work with your technical staff to answer questions, make changes and provide technical documentation. Where necessary, we assist with regulatory certifications and compliance. As new pumps are released to production, Diener’s pump engineering team is there to help debug any system-level issues and ensure a smooth product launch.

Diener Precision Pumps’ manufacturer reputation for technical design excellence, fast pump prototyping, superior quality, and ongoing customer service are the reasons we are the preferred partner for your OEM pump manufacturing requirements.
