Booster Pump Head
The 400G Pump Head acts as the central booster head for 400-GPD reverse-osmosis (RO) systems. Thus, it creates the necessary pressure to drive water through RO membranes and ensures efficient water purification. Moreover, it supports various types of 400-GPD pumps, giving you flexibility and compatibility no matter which pump brand you use. Water Purification Systems+2Water Purification Systems+2
Because the head is built for high-pressure and low-flow applications, it suits RO systems where strong pressure matters more than raw flow. Water Purification Systems+1 Additionally, it’s designed to handle operation even if water supply fluctuates — and it can run dry without damaging the motor, which adds an important layer of safety and durability.

Therefore, when you install the Fluxtek 400G Pump Head, you benefit from steady pressure, consistent purification performance, and increased longevity of your pump system. Because of these qualities, it remains a smart choice for domestic water filtration, commercial RO setups, water shops, or anywhere reliable, clean water output is essential.
Key Features & Benefits
- Supports 400 GPD RO booster pumps — making it ideal for standard home or commercial reverse-osmosis systems.
- Optimized for high-pressure, low-flow operation — suitable for RO purification where pressure matters.
- Designed to run dry without damaging the motor — helping prevent burnout or failure when the water supply is disrupted.
- Broad compatibility — works with different brands and types of 400 GPD pumps, giving installation flexibility.
- Reliable and durable construction — helps maintain stable pressure and consistent water flow over time, which supports clean, safe water delivery.
Typical Applications & Use Cases
- Reverse-osmosis water filtration systems in homes or small offices, where 400 GPD capacity is standard.
- Commercial water purification setups — where stable pressure and reliability matter.
- Water shops or bottled-water facilities — needing consistent high-pressure pump heads for filtration and bottling.
- Any clean-water supply system relying on a 400 GPD pump output (e.g., for drinking water, small-scale production, or purification before use).
- Backup or replacement head for existing 400 GPD RO systems — enabling repair and maintenance without replacing entire pump assemblies.
