In the intricate world of industrial fluid handling, accuracy and reliability are paramount. Metering pumps, particularly those adhering to the stringent standards of API 675, play a vital role in ensuring precise delivery of fluids across various industries, from chemical processing to pharmaceuticals. At the forefront of this technology stands Flowell (Shanghai) Industrial, a pioneering manufacturer renowned for its innovative designs and durable products.

Core Technological Advancements

Hydraulically Balanced PTFE Diaphragm: A Step Ahead in Durability

One of Flowell's cornerstone innovations lies in its hydraulically balanced PTFE (Polytetrafluoroethylene) diaphragm. Engineered specifically for an unparalleled operating life of 96,000 hours, this diaphragm redefines the standard for metering pump durability. Unlike conventional designs, it does not rely on seals, thereby eliminating the need for frequent plunger packing maintenance—a significant cost and time saver for end-users. The absence of seals also contributes to enhanced fluid containment, ensuring purity and precision in even the most demanding applications.

Liquid End Bleed System: Simplifying Commissioning

To further streamline pump maintenance and commissioning, Flowell has introduced an innovative liquid end bleed system. This system greatly simplifies the process of preparing a new or newly serviced pump for operation, allowing technicians to easily flush out trapped air and contaminants without dismantling the pump's internals. This not only accelerates the commissioning process but also minimizes the risk of operational issues arising from improper installation or maintenance.

Worm and Pinion Drive: Precision Meets Durability

At the heart of Flowell's API675 metering pumps lies a precision-engineered worm and pinion drive system operating in an oil bath lubrication environment. This configuration produces a silky smooth mechanical motion, minimizing wear and tear that typically plague mechanical lost motion designs. The result is not only reduced friction and noise but also a substantial increase in the lifespan of gears and bearings, ensuring long-term reliability and minimal maintenance requirements.

Dust-Tight Cast Iron Housing: Ruggedness for Harsh Environments

Understanding the rigors of industrial operations, Flowell has crafted its metering pumps with a dust-tight cast iron housing. This robust enclosure provides exceptional protection against environmental contaminants, making it an ideal choice for use in the toughest plant and field environments. The cast iron construction not only ensures structural integrity but also enhances the pump's ability to withstand corrosion and abrasion, extending its service life and reducing the need for repairs.

Conclusion

Flowell (Shanghai) Industrial's API675 metering pumps represent the pinnacle of technological advancement and innovation in fluid handling. By combining cutting-edge design features such as the hydraulically balanced PTFE diaphragm, liquid end bleed system, worm and pinion drive, and dust-tight cast iron housing, Flowell has created a pump that balances precision, durability, and reliability. For companies seeking to optimize their fluid metering processes, Flowell's offering is not just a pump—it's the key to unlocking unparalleled accuracy and performance.
