Collection: Booster Pump Sets

It depends on your gas types and fill volume:

• 220/1 set = built on the single-piston 220/1 pump, made for rebreather divers.
• 220/2 set = built on the double-piston 220/2 pump, made for rebreather doubles, bailout, and stage cylinders.
• 300/2 set = built on the high-capacity double-piston 300/2 pump, made for commercial dive centers and filling storage tanks.

Tell us your gas types, supply pressure, and how often you fill and we'll recommend the right set.

The drive-air hose (for example, the 2 m antistatic hose with NW 7.2 coupling) supplies the compressed air that powers the booster. A filling hose carries the boosted high-pressure gas to the cylinder you're filling. The overflow hose (such as the 1.65 m digital version with manometer and DIN G5/8" connection) is used to decant or equalise gas between cylinders. Choose based on which side of the process you're connecting.

These are build options so you can buy the pump at the level of integration you need:

• Without piping, the booster pump on its own, ready for you to connect into your existing setup.
• Pre-piped, supplied with the high-pressure piping already fitted, so it's quicker to install and put into service.
• With overflow unit, pre-piped and fitted with an overflow/relief unit for added pressure management and safety during filling.

If you'd rather have a complete, ready-to-go kit with hoses, manometer, and fittings in a waterproof case, look at our Booster Pump Sets.

The booster pump itself is supplied ready for connection (the exact piping depends on the variant you choose). To run it you'll typically need a compressed-air drive supply, filling hoses, the correct adapters for your cylinders, and oxygen-safe grease for oxygen service. You can find filling hoses, adapters, oxygen-safe lubricants, and other compatible parts in our Booster Pump Accessories collection.
