The STRATEC Piston Pump is a cost-optimized solution for reliable liquid dispensing mainly in OEM applications for IVD systems. The Piston Pump provides flexible volume delivery, from one single stroke to freely adjustable multiple dispense operations, supporting a wide range of application requirements. The pump chamber is designed as a cost-efficient service part and can be replaced easily, helping maintain the specified precision and accuracy over time.
This OEM piston pump combines high precision and reliability with plastic piston and cylinder units that are easy to access and replace. A priming protocol helps ensure bubble-free fluid dispense, while a full stroke counter supports preventive maintenance. The pump also features a light barrier, which monitors the proper movement of the pump motor and therefore the aspiration and dispense of the liquid.

Frequently Asked Questions
- What are the main advantages of the STRATEC Piston Pump?
The STRATEC Piston Pump combines precision, reliability, and cost efficiency in a compact OEM design. The pump supports process control and monitoring through an integrated sensor, while the exchangeable pump chamber and plastic wearing components help reduce maintenance effort and support long-term use.
- What is the main application?
The STRATEC Piston Pump is particularly well suited for reliable wash buffer dispensing and other system fluids such as deionized water in OEM analyzer systems. It is designed for applications that require precise and controlled liquid delivery.
- How does the STRATEC Piston Pump support preventive maintenance?
A full stroke counter tracks pump usage and supports preventive maintenance. In addition, the pump chamber can be replaced as a service part, helping maintain the specified precision and accuracy over time.
- What kind of configuration options are available?
The STRATEC Piston Pump is available either as a sub module, where drives and sensors are controlled by a parental module, or as a stand alone module, with the drives and sensors controlled by its own PCBA interface. This provides flexibility for different OEM instrument architectures.
- How flexible is the volume delivery?
The STRATEC Piston Pump has a nominal volume of 2500 µL and the recommended operating range is between 200 to 2500 µL. It also supports flexible volume delivery, ranging from a single stroke to freely adjustable multiple dispense operations, allowing the pump to be adapted to different application requirements.
