323U/D Peristaltic Pump: Precision Fluid Handling with Flexibility and Reliability

The Watson-Marlow 323U/D peristaltic pump is an fluid-handling solution tailored for a wide range of applications requiring precise flow control and easy operation. This pump offers exceptional versatility, accommodating flow rates from 0.81 to 2000 ml/min, making it suitable for both low and high-volume fluid transfer tasks. Designed with user convenience and reliability in mind, the 323U/D is ideal for laboratories, chemical processing, food and beverage, and industrial environments where consistent and repeatable fluid management is essential.

At the core of the 323U/D is a quiet brushless DC motor that ensures long-lasting performance with zero maintenance requirements. The motor’s silent operation makes it suitable for noise-sensitive environments, while its durable construction enhances the pump's overall lifespan. The pump features a compact design, integrating a high-visibility digital display and membrane keypad for straightforward control. The digital interface provides precise speed settings and easy monitoring, allowing users to achieve exact flow rates and make quick adjustments when necessary.

The pump’s construction consists of a robust chemical-resistant case that safeguards the internal components from harsh environments and aggressive fluids. This durability, combined with a powder-coated aluminum drive base and self-colored ABS plastic drive top, ensures the pump remains reliable over an extended period. Additional components such as the glass-filled polypropylene and IXEF used in the pumphead add further chemical resistance and structural integrity.

One of the standout features of the 323U/D is its tube loading system. The pump utilizes the 313DW flip-top pumphead, allowing for rapid tube changes with minimal downtime. The pumphead is compatible with tubing of 1.6mm wall thickness, providing an efficient and straightforward setup. For applications that demand higher suction or pressure, alternative pumphead options are available, such as the 313DW2 and 314DW2. The 313DW2 three-roller pumphead supports thicker 2.4mm wall tubing and can achieve delivery pressures up to 2 bar, while the 314DW2 four-roller pumphead also accommodates higher pressure applications for continuous duties up to 300 rpm.

For more complex fluid handling needs, the 323U/D can be expanded using snap-fit 313X extension pumpheads, enabling up to six channels of flow for multi-stream operations. This adaptability makes it suitable for applications where multiple fluids need to be pumped simultaneously, offering significant flexibility in system design.

The pump's control system supports a wide speed range of 3-400 rpm, with a control ratio of 133:1, ensuring precise regulation of fluid flow across different operating conditions. The 323U/D also meets several safety and performance standards, including CE, IEC335-1, and EN60529 (IP31), providing users with confidence in its quality and compliance.

Suitable for operating temperatures from 5°C to 40°C (40°F to 104°F), the 323U/D can withstand a variety of environmental conditions. The pump is designed to maintain a noise level below 70 dB(A) at a distance of 1 meter, ensuring a quiet operation that does not disrupt the working environment.

The Watson-Marlow 323U/D is a versatile, durable, and user-friendly peristaltic pump that delivers precise fluid handling solutions across multiple industries. With its robust construction, flexible pumphead options, and straightforward control interface, it is an ideal choice for professionals seeking reliable and efficient fluid management.
