Flojet / ITT Water Pressure System Pumps

Flojet / ITT Water Pressure System Pumps: On-Demand Reliability Afloat and On the Road

When consistent water pressure is non-negotiable — whether aboard a vessel or in a recreational vehicle — Flojet / ITT stands out as one of the most trusted names in the business. Water pressure system pumps from Flojet combine decades of engineering expertise with field-proven diaphragm technology, delivering the kind of dependable, on-demand performance that marine and RV enthusiasts rely on every day.

A Legacy of Diaphragm Innovation

Flojet traces its roots back to 1975, when it was established with a focus on special-application pumps. Today, as part of the Xylem family of brands, it has grown into a leading global supplier of compact, precision pumps across marine, RV, industrial, and beverage applications. In the water pressure system category specifically, Flojet's co-molded diaphragm technology is a key differentiator — engineered for long service life and smooth, quiet operation even under varying demand conditions.

What Sets Flojet Water Pressure Pumps Apart

Flojet's water pressure system pumps are purpose-built for applications where pressure is low, fluctuating, or must be delivered on demand. The 2840 Series Booster Systems, for example, are designed to deliver constant pressure with a fully integrated inlet strainer, pressure switch, and check valve — all in a single, easy-to-install package. Whether mounted vertically or horizontally, these systems adapt to tight installation spaces common on boats and in RVs.

• Integrated sealed pressure switch for fully automatic, on-demand operation — the pump runs only when a tap is opened
• Internal bypass valve that reduces pump cycling and minimizes noise during operation
• Self-priming capability (up to 9 ft. suction lift) for flexible installation above the water or tank source
• Quick-connect ports for fast, tool-free installation, servicing, and maintenance
• Vibration-dampening mounting feet to cut down on noise and vibration transmitted to the hull or chassis
• Thermal motor protection to prevent overheating, even during extended use
• CSA-certified for potable water, making them safe for drinking water systems
• Available in 12V DC, 24V DC, and 115V AC configurations to match virtually any vessel or vehicle electrical system

Designed for Marine and RV Water Systems

Flojet's water pressure pumps are a staple in both marine and RV freshwater plumbing. They are designed to fulfill water pressure requirements for the majority of RV and marine applications, and their compact, durable construction makes them well-suited to the space constraints and vibration environments found in both settings. Heavy-duty (HD) models feature larger motors and cast aluminum lower housings for long-life performance even at elevated pressures — an important consideration for larger vessels or rigs with multiple fixtures.

The polypropylene housings resist corrosion, while elastomer options ensure compatibility with potable water systems. A built-in backflow prevention valve adds an extra layer of system protection, and most models include an inlet strainer to keep debris out of the pump mechanism.

Easy Installation, Minimal Maintenance

One of the reasons Flojet water pressure system pumps remain a go-to choice is their straightforward installation. On the booster system models, setup requires little more than connecting water lines and plugging in the power cord. Combined with accessible quick-connect ports and widely available OEM replacement parts — including diaphragms, valves, and strainers — keeping a Flojet pump running at peak performance over the long haul is as easy as the initial install.
