Pumpmaster Aquafos SPT-003 3L Steel Pressure Vessel Tank 25mm Connection

The Pumpmaster Aquafos SPT-003 is a compact steel pressure vessel designed to stabilise water pressure and improve pump system efficiency in domestic and light commercial water supply systems. With a 3-litre capacity and durable steel construction, this pressure tank helps reduce pump cycling, maintain consistent pressure, and extend the life of connected pumps in pressure boosting and water transfer systems.

The tank is constructed with a polypropylene internal liner and a high-grade butyl diaphragm that separates air and water, creating a closed system that maintains stable pressure while preventing contamination or bacterial growth in drinking water applications. A corrosion-resistant epoxy coated exterior and 304 stainless steel water connection provide durability and long service life in demanding water system environments.

Designed for reliable operation, the SPT-003 pressure vessel is rated for a maximum working pressure of 10 bar and liquid temperatures up to 90°C. The tank is factory tested to ensure structural integrity and includes a leak-free O-ring sealed air valve cap for easy pressure adjustment and maintenance-free operation. Suitable for use with booster pumps, pressure systems, and water transfer setups, this compact vessel is ideal for installations where space is limited but pressure stability is required.
