Collection: Fluid-o-Tech Pump 3/8" NPTF 111 Max

This specialized collection features professional-grade Fluid-o-Tech rotary vane pumps engineered specifically for precise fluid transfer in small- to medium-sized commercial applications. Built around the renowned Rotoflow® technology, these compact, positive displacement pumps deliver a highly reliable, pulse-free flow, making them a staple component for commercial espresso machines, beverage dispensing equipment, and reverse osmosis (RO) boost systems.

Designed for seamless integration into standard commercial setups, every pump in this collection is equipped with 3/8" NPTF inlet and discharge ports and is capable of accommodating flow rates up to a maximum of 111 gallons per hour (GPH). To meet diverse fluid compatibility and regulatory requirements, the collection offers multiple housing constructions, including standard brass, eco-friendly no-lead brass (PB series), and high-grade stainless steel for maximum corrosion resistance in high-purity or sanitary environments.

Most models within this category feature an integrated, adjustable bypass valve. This built-in relief mechanism allows operators to easily set and maintain the system's maximum operating pressure, safely diverting excess flow back to the inlet side when the system is dead-headed or restricted. Combined with their self-lubricating carbon graphite internals, these pumps provide facility operators and equipment manufacturers with an exceptionally durable and highly efficient fluid control solution.
