Chemical Injection Pumps for the Oil & Gas Industry

By choosing an SiA chemical injection pump for your system, you can be assured you’re getting the highest quality at a competitive price. All our pumps:

  • Are Suitable for a Wide Range of Applications

    Tailored to your application for best results. Offshore and other hazardous area certification options available (IECEx, UL/CSA).

  • Have High Chemical Containment & Compatibility

    Latest dual seal technology using stainless steel filled Teflon for long seal life. 100% ceramic plungers as standard.

  • Are Easy to Install

    The SiA Connector makes it easy to turn the port to face the pipework and no tools are required to separate the drive from the liquid end. The SiA Connector also allows interchangeability between electric-driven and pneumatic/gas driven pumps.

  • Allow Accurate Control

    Accurately maintain set injection rates irrespective of well head pressure or ambient temperature fluctuations. Our unique manual stroke adjustor allows extremely high turn down rates and can set the stroke from 0-100%.

  • Are Reliable & Low Maintenance

    Increased reliability between servicing. No inline lubrication required.

  • Are Designed and Built to the Highest Standard

    Designed and manufactured in Australia and backed by a 12 month warranty.
