Diener Precision Pumps - A quality manufacturer of precision pumps and valves

Diener Precision Pumps is a Swiss quality manufacturer of precision pumps and valves. The privately owned engineering company, run by engineers for engineers, designs and manufactures piston pumps, gear pumps and valves for OEM fluid handling systems worldwide.

Superior performance, long life and quality as well as a high cost-effectiveness characterise the products of Diener Precision Pumps. All piston pumps, gear pumps and valves are tailored exactly to the individual customer application. The precision pumps and valves are developed at Diener Precision Pumps' centre of innovation in Lodi, California, US, and are produced at the company's headquarters in Embrach, Switzerland.

Gear pumps for OEM fluid handling systems

The magnetic coupled gear pumps of Diener Precision Pumps are designed for OEM market applications. They are simple and leak-free. The pumps combine relevant features for their use in medical, laboratory, diagnostic and analysis equipment. These include pulse-less flow, even at high pressure, resistance to chemically aggressive fluids, manifold mounting options, durability and ease of cleaning. The enhanced gears and shaft bearings have been optimised to ensure a long, trouble-free life and very low power consumption. We manufacture every component using Diener Precision Pumps' superior production techniques, resulting in a very high-quality product at a relatively low cost.

Piston pumps for different applications

The Precision series piston pumps were developed specifically for applications requiring a very exact flow at a fast dispense rate. The positive displacement piston pumps ensure accurate and repeatable flow rates. The piston geometry isolates the outlet and inlets without the need for internal check valves, simplifying the construction and reducing flow restriction. The pumps are typically provided in a fixed position to deliver a set flow-per-stroke. An adjustable mounting frame is optional, allowing the pump displacement to be altered in the field and then locked in position. Their speed sensing options include encoders, hall sensors and/or photo detectors. The displacement algorithm is well-defined, allowing the end user to correlate motor position with the amount of fluid dispensed. The piston pumps are available with stepper, brush-less DC, and brush-type DC motors.

Valves for precise fluid control

The Solenoid valve series is designed specifically for medical and food/beverage applications. The wetted materials are biocompatible with a wide range of fluids and the small dead volume is easily cleaned-in-place. A wide array of tube fitting options and simple mounting flanges make the valves easy to install. The plunger is isolated from the fluid with a PTFE bellows and is available in the normally closed (NC) configuration. Fast switching times and low holding current mean low heat transfer to the fluids. The environmental protection is IP 65, ensuring robust performance in harsh locations. The wetted materials are compatible with aggressive fluids. The solenoid valves have a very low dead volume. They are easy to clean, compact and extremely quiet.

Tailored exactly for the individual customer application

All our gear pumps, piston pumps and valves are customised to suit your requirements. Rather than provide off-the-shelf products, we work with our customers' engineers to design and optimise pump/valve performance and enhance your equipment performance. Low power consumption is a key part of low-flow applications - our gear pumps, piston pumps and valves are optimised for maximum efficiency. We present a menu of design alternatives and work with you to minimise your installed cost. All raw materials are 100% lot-traceable. All gear pumps, piston pumps and valves can be permanently laser-marked with the customer's logo to ensure they maintain control of their aftermarket. They are 100% tested prior to shipment (test results are included with each pump and valve).

Production site in Embrach, Switzerland

In August 1994 Rolf Diener, Doug Robinson and John Bishop establish the company Diener Precision Pumps in Switzerland. Six years after its formation, Diener Precision Pumps gets a new state-of-the-art production plant in the Swiss town of Embrach. Since its foundation, the name Diener Precision Pumps" stands for high-quality precision pumps and valves. This is officially acknowledged through the certification according to medical standards ISO 9001/ISO 13485 and the establishment of a clean room according to ISO class 7. All gear pumps, piston pumps and valves are designed specifically for your application and are thoroughly engineered to ensure long life and trouble-free operation. Diener Precision Pumps design unnecessary cost out of the products. The part tolerances of Diener Precision Pumps are typically in micrometres, ensuring pump and valve performance is consistent. Environmentally friendly packaging will protect your gear pumps, piston pumps and valves all the way to your production floor.

Centre of development and innovation in Lodi

The facility in Lodi, US, is the innovative heart of Diener Precision Pumps. A team of highly specialised engineers tailors the magnetically coupled gear pumps, the precise piston pumps and the solenoid valves exactly to the individual OEM customer requirements, always in close cooperation with the customers' engineers. The transfer and production happens in Embrach, Switzerland.
