Flow catalysis requires highly accurate fluid delivery under elevated pressures and temperatures. Eldex Optos Series high-pressure metering pumps provide repeatable flow rates from 2 µL/min to 80 mL/min, pressures up to 6,000 psi, and fluid temperature capabilities up to 260°C. Their rapid-retract design minimizes pulsation, while configurable wetted materials support aggressive chemical applications. These capabilities make Optos pumps ideal for catalytic reactor feed systems, hydrogenation, polymerization, and continuous-flow process development.
Why are High-Pressure Metering Pumps Critical for Flow Catalysis?
Increasingly, researchers and process engineers are moving from traditional batch systems to continuous-flow platforms. Flow catalysis has become a cornerstone of modern chemical R&D because it enables:
- Improved safety, tighter process control, and better product quality and consistency
- Continuous operation with improved scalability from lab to pilot-scale production
- Enhanced safety when handling reactive intermediates
- Precise control of reaction conditions, leading to reproducible outcomes
These advantages depend on a fluid delivery system capable of handling high pressures, elevated temperatures, and chemically aggressive fluids while maintaining stable, repeatable flow.
Optos Pumps: Engineered for High-Pressure Precision
The Eldex Optos Series is designed for demanding applications such as high-pressure catalysis and continuous process development.
High Pressure and Temperature Capability
- Configurable flow rate range up to 80mL/min
- Operating Pressures up to 6000 psi
- Specialized configurations for fluid temperatures up to 260°C
Reduced Pulsation Through Rapid Retract Design
Pulsation is inherent in reciprocating piston pumps due to their stroke cycle. Eldex reduces this effect through a rapid-retract feature that refills the pump cylinder as quickly as possible, thereby minimizing fluid and pressure pulsations.
By shortening the refill portion of the cycle, the system reduces the amount of time the outlet pressure falls below the mean operating pressure. When combined with optional pulsation dampers, pressure fluctuations can be further reduced for applications sensitive to flow instability.
Highly Repeatable Flow Delivery
The reciprocating piston design delivers highly repeatable flow because the same volume of fluid fills the cylinder on each stroke.
Flow accuracy is further refined through Eldex compression factor settings that enable calibration based on the working fluid’s specific density and viscosity, allowing customers to optimize accuracy directly at their installation site under exact process conditions.
Flexible Flow Range and System Scaling
- Configurable liquid ends allow flow rates from 2 microliters to 80 mL/min
- Suitable for both laboratory-scale R&D and pilot-scale process systems
This flexibility allows researchers to maintain consistent pump architecture while scaling processes from development through larger continuous-flow platforms.

Frequently Asked Questions
What pump is best for flow catalysis?
Flow catalysis applications typically require high-pressure metering pumps capable of delivering stable, repeatable flow under varying process conditions. The Eldex Optos Series supports pressures up to 6,000 psi and flow rates from 2 µL/min to 80 mL/min.
Why is pulsation important in flow chemistry?
Excessive pulsation can affect reaction consistency, catalyst performance, and analytical measurements. Minimizing pulsation helps maintain stable reaction conditions and reproducible results.
What pressure is required for flow catalysis?
Pressure requirements vary by process, but many catalytic reactor systems operate from several hundred psi to several thousand psi. High-pressure pumps are commonly used to support these conditions.
