MEGA-40 is a pressurized water system component designed for high-rise buildings, fire systems, and demanding long-distance pressure support. With a 40-liter (10-gallon) capacity, it reliably maintains water pressure at a set, consistent level.
Built for high-stress environments, this tank supports a robust 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 29.0 cm in diameter and 56.4 cm in height, this durable tank is designed for high-capacity needs. It is an ideal solution for robust residential and commercial booster pump setups requiring exceptional high-pressure performance.

Product Overview
The MEGA-40 is a 40-liter (10-gallon) high-performance diaphragm tank, engineered as the definitive solution for compact residential and light commercial water system stabilization. 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-40 offers superior oxidation resistance. Equipped with a premium 1” 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-40 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 MEGA-40 (40L) delivers a 5.5L/min flow rate, providing stable pressure for simultaneous high-demand household tasks. Unlike standard 10-bar tanks, its 16-bar (232 PSI) rating and Nitrogen pre-charge ensure a maintenance-free lifespan. Compact at 29.0 x 56.4 cm, it uses 304 Stainless Steel to guarantee durability and water purity.
The MEGA-40 combines three elite features rarely found together in the industry: a 16-Bar pressure rating for extreme durability, a 100% Nitrogen pre-charge to eliminate pressure loss, and a 304 Stainless Steel connector to guarantee rust-free, hygienic operation.
No. The MEGA-PLUS series is designed to ensure the water system works efficiently and saves energy with no maintenance required. The 100% nitrogen factory pre-charge also helps prevent the air loss typical in standard tanks.
