The ELBI AFV200 vertical pressure vessel (SKU: 022-590) is a 200-litre accumulator designed for booster pump systems, domestic and light industrial water installations, and potable water applications. Built with a replaceable EPDM bladder, epoxy powder coated shell and a compact vertical footprint, this AFV series tank improves system stability by reducing pump cycling and acting as a water-hammer damper.

Key Features

• Capacity: 200 L (200 litres)
• Replaceable EPDM diaphragm / bladder (food-grade, suitable for potable water)
• Main connection: 1¼" (DN 1¼), auxiliary connection: ¾"
• Working pressure typically up to 8 bar with max operating rating to 10 bar (model specific)
• Durable blue epoxy powder coating for corrosion resistance
• Compact vertical dimensions ~ Ø600 mm × H≈1035–1065 mm
• Temperature range and long life design (operating temperatures from about -10°C to +99°C depending on variant)

Performance & Applications

The AFV200 bladder tank stores water under pressure so your booster pump runs less frequently, improving energy efficiency and extending pump life. Its full separation of water and air prevents corrosion and contamination, while the interchangeable diaphragm simplifies maintenance and reduces downtime. Typical uses include domestic booster sets, small commercial pressure boosting, irrigation and systems where consistent delivery pressure is required.

Install vertically on a flat surface; blank or valve the auxiliary port if unused. Verify pre-charge pressure before commissioning (manufacturer-recommended pre-charge values apply) and size the tank to match pump duty and system pressure setpoints. For model-specific ratings, compatibility and warranty details consult the manufacturer documentation or distributor datasheet.
