Flojet VersiJet 4-Chamber Diaphragm Pump – 24V, 3.5 GPM, 50 PSI (Q352F-16N7-2P)

The Flojet VersiJet 4-Chamber Diaphragm Pump (Q352F-16N7-2P) is a premium 24V DC water pump designed to deliver smooth, high-pressure water flow for demanding marine, RV, and off-grid applications. Built with advanced engineering and durability in mind, this pump provides up to 3.5 gallons per minute (GPM) at 50 PSI, ensuring reliable performance for pressurized water systems.

Advanced 4-Chamber Technology for Superior Performance

Unlike traditional 2- or 3-chamber pumps, the VersiJet’s 4-chamber diaphragm design significantly reduces pulsation and water hammer, resulting in quieter operation, smoother flow, and improved system efficiency. This means less vibration throughout your plumbing system and a more consistent water experience at faucets, showers, and fixtures.

Smart Pressure Control & Automatic Operation

The built-in pressure switch automatically turns the pump on and off as demand changes, maintaining steady water pressure without manual control. This intelligent operation helps conserve energy while extending the life of both the pump and your plumbing components.

Reliable Self-Priming & Dry-Run Protection

The VersiJet pump is self-priming, allowing it to draw water even when mounted above the water source, making installation flexible and straightforward. Additionally, dry-run protection safeguards the pump from damage when water supply is interrupted—ideal for mobile or variable water systems.

Built for Harsh Environments

Engineered with corrosion-resistant materials and a rugged housing, this Flojet pump is built to withstand marine conditions, vibration, and continuous use. Its sealed motor and durable components ensure long-lasting reliability whether you're offshore or on the road.

Key Features:

• Heavy-Duty Construction: Features a TENV (Totally Enclosed Non-Ventilated) permanent magnet motor with a coated shell and a cast aluminum lower housing for superior heat dissipation and corrosion resistance.

• Chemical Resistance: Equipped with Viton seals and valves and a Santoprene diaphragm, this pump is compatible with a wide range of fluids, including harsh chemicals and abrasives.

• Intelligent Design: The internal bypass helps reduce pump cycling and noise, while the noise-dampening baseplate with rubber feet minimizes vibration during operation.

• Safety & Reliability: The motor includes thermal protection (TCO) to prevent overheating during intermittent duty cycles. It is also run-dry capable and self-priming up to 8 feet (2.4m).

Why Choose the Flojet VersiJet Q352F-16N7-2P?

The Flojet VersiJet series is known for combining high performance, quiet operation, and long-term reliability. This model stands out with its enhanced flow consistency and reduced noise, making it a top choice for users who demand comfort and dependability in their water systems. Whether you're upgrading an existing setup or building a new one, this pump delivers professional-grade performance with minimal maintenance.

Upgrade your water system with the Flojet VersiJet 24V Diaphragm Pump and enjoy consistent pressure, quiet operation, and dependable performance wherever your journey takes you.

Installation Tip: Since this model lacks an integrated pressure switch, it is critical to ensure your system can handle the internal bypass or that you have an external method to shut the pump off when flow is not needed. To prevent debris from damaging the Viton valves, I highly recommend installing a Flojet 1/2" Port Strainer on the inlet side.
