Pneumatic/Gas Driven Pumps

Inherently suitable for hazardous areas the SiA Pneumatic/Gas range of pumps delivers safe, efficient and effective chemical injection you can rely on.

Experts in chemical injection solutions

Pneumatic/Gas Driven Pumps

Just like all SiA chemical injection pumps, our AC range delivers: accurate injection rate control; high chemical containment & compatibility; reliability & low maintenance; quality design; and options for offshore and other hazardous area certifications.

Plus a unique ability to interface with SiA electronic controllers for higher levels of accuracy and repeatability with remote control and monitoring when used with a small solar panel.  Low drive gas venting with 50% reduction in venting of drive gases into the atmosphere on some models, when compared with competitors’ double acting drives.
