MEGA-8 is a pressurized water system component designed for high-rise buildings, fire systems, and long-distance pressure support. With an 8-liter (2.0-gallon) capacity, it reliably maintains water pressure at a set, consistent level.
Engineered for high-stress environments, the tank supports a maximum operating pressure of 16 bar. It is factory-pre-charged with 100% nitrogen to ensure stable performance and prevent pressure fluctuations caused by temperature changes.
Measuring 20.3 cm in diameter and 30.1 cm in height, this compact tank is designed for point-of-use installations. It is an ideal solution for booster pump setups requiring exceptionally high-pressure performance in a smaller footprint.
Product Overview
The MEGA-8 is an 8-liter (2.0-gallon) high-performance diaphragm tank, engineered as the definitive solution for small-scale residential systems and targeted thermal expansion protection. Utilizing a specialized FDA-grade polypropylene liner integrated with a premium butyl diaphragm, it ensures a dedicated "Safe Water Zone" by preventing any contact between the liquid and the tank's metallic shell.
Key technical advantages include a 100% Nitrogen pre-charge and a 16-bar (232 PSI) pressure rating, which significantly outperforms standard industry tanks. This configuration ensures more stable pressure cycles and minimizes pump "short-cycling," directly preventing motor burnout and extending equipment lifespan.
Constructed with a heavy-duty cold-rolled carbon steel shell and protected by a triple-grade epoxy powder finish, the MEGA-8 offers superior oxidation resistance. Equipped with a premium 304 Stainless Steel lead-free connector, this CE and ISO 9001 certified unit provides an energy-saving, maintenance-free solution for critical high-pressure applications.

Key Features & Design Advantages
How the MEGA-PLUS Pressure Tank Works
The MEGA-8 stores supplemental water between the liner and the heavy-duty butyl rubber diaphragm. When a faucet is opened or an appliance demands water, the compressed nitrogen air chamber pushes the stored water into the system. This allows the system to meet low-volume water demands without immediately triggering the pump motor. By creating this efficient supply cycle, the tank minimizes pump cycling, stabilizes water pressure, and conserves energy.

Frequently Asked Question (FAQ)
The 8-liter (2.0 gallon) MEGA-8 supports a 1.5L per minute flow rate, making it an excellent energy-saving addition to a high-pressure booster system.
Yes. By storing supplemental pressurized water, the MEGA-8 reduces the number of times your pump motor needs to turn on for small water demands. This ensures your water system works far more efficiently and saves energy.
Brass and regular steel can easily rust or wear out. The 304 Stainless Steel connection on the MEGA-8 stays rust-free and lasts much longer without leaking or breaking.
