Sealless Centrifugal Pumps in Practice:
Types, Design and Selection Insights, and API 685 Overview
- Design 4 -
Description:
Sealless centrifugal pumps have become a preferred solution for handling hazardous, corrosive, and high-purity fluids in industries where leakage prevention and environmental safety are paramount. This presentation will provide a comprehensive overview of sealless pump technologies, including magnetic drive and canned motor designs, as well as multistage sealless pumps, which are increasingly being adopted for high-head applications in chemical and energy sectors.
The session will explore the types, applications, merits, and demerits of sealless centrifugal pumps, supported by field experience and engineering evaluations from various projects. A dedicated segment will highlight key aspects of API 685, the governing standard for sealless pumps in petroleum, chemical, and gas industry services, with practical insights into compliance and specification challenges.
The content for presentation is prepared by based on experience of working with Sealless pump products from all major global suppliers and delivered in various technical forums over the past 7+ years.
This topic is gaining significant traction across the pump engineering community and will also be presented (by another presenter) at this year’s Turbomachinery Symposium in Houston, underscoring its relevance and importance. Attendees will leave with a deeper understanding of how sealless technologies can enhance reliability, reduce maintenance, and support safer operations in demanding environments.
