SHARE
Liquiflo's H-Series Gear Pumps are a modern iteration of the older 3-Series, adeptly catering to new applications while providing an optimal upgrade path for existing setups. These gear pumps, constructed using high-grade materials such as 316 Stainless Steel, Alloy-C, and Alloy-20, offer flexibility with both Sealed and Mag-drive configurations. With flow rates reaching up to 55 gallons per minute and capable of handling differential pressures up to 100 PSI, they are well-suited for demanding industrial environments. Key to their design is the versatility in connection options, such as threaded and flanged ports, allowing integration into diverse systems. Their robust construction ensures reliability across various operational conditions, making them a preferred choice in advanced fluid handling solutions. The transition from 3-Series to H-Series involves adopting these modern features for enhanced performance and longevity.
