Flojet / ITT Engine Water Pump

Flojet / ITT Engine Water Pumps: Precision Engineering You Can Rely On

When it comes to dependable fluid management in demanding environments, few names carry the weight of Flojet / ITT. Established in 1975 as a specialist manufacturer of application-specific pumps, Flojet has grown into one of the world's most recognized small-pump brands — and their engine water pumps reflect decades of refinement in diaphragm pump technology.

Flojet's journey through the pump industry is inseparable from its ITT heritage. When ITT acquired Flojet, the brand gained access to expanded engineering resources and a global manufacturing infrastructure, accelerating product development and pushing Flojet's pump designs into new performance tiers. Today, operating under the Xylem umbrella, Flojet continues to build on that ITT legacy of precision-engineered fluid solutions for marine, RV, automotive, and industrial applications.

What Sets Flojet / ITT Water Pumps Apart

At the heart of Flojet's engine water pump lineup is its signature diaphragm pump technology. Unlike many competitors, Flojet pumps are engineered to run dry without sustaining damage — a critical advantage when installations are subject to intermittent supply or variable prime conditions. This run-dry capability, combined with robust self-priming performance, means Flojet pumps can be positioned above the fluid source without sacrificing reliability.

• Self-priming design: Flojet engine water pumps can self-prime up to several feet, offering flexible installation in tight engine compartments or RV bays.
• Run-dry capability: Pumps continue to operate safely even when the fluid source is temporarily interrupted — no burnout, no immediate damage.
• Quad and duplex diaphragm configurations: Flojet's four-chamber design minimizes pulsation and delivers smooth, consistent flow rates essential for engine cooling circuits.
• Co-injection mold diaphragm technology: Used across VersiJet and related pump series, this construction technique extends pump service life and maintains seal integrity across a broad temperature range.
• Polypropylene housings with elastomer options: Flojet pumps feature durable polymer housings and interchangeable diaphragm and seal materials, allowing compatibility with fresh water, treated water, and mildly corrosive fluids.
• Multiple voltage options: Engine water pumps in the Flojet lineup are available in 12V DC configurations ideal for marine and RV engine systems, as well as higher-voltage variants for industrial engine applications.

Why Flojet / ITT for Engine Water Pumps?

Engine water pumps are a mission-critical component — whether managing coolant circulation, raw-water intake for marine engines, or water system pressure in motorized applications. Flojet / ITT's decades of OEM presence in boats and recreational vehicles speaks directly to their suitability for these roles. Marine engine builders and RV manufacturers have long specified Flojet pumps on the production line, a testament to their durability and consistent performance under real-world operating conditions.

The brand's commitment to what Xylem calls continuous improvement means that each generation of Flojet engine water pumps incorporates engineering refinements — quieter operation, more efficient motor designs, and snap-in or quick-connect port fittings that simplify installation and servicing. Whether you're replacing a failed OEM pump or upgrading a marine cooling circuit, Flojet / ITT offers a catalog of proven performers backed by a legacy of precision pump manufacturing.
