Chemical Injection Pump Systems

Our chemical injection pump systems are used in onshore and offshore hazardous areas. We specialise in the design and manufacture of both API 674 and API 675 chemical injection packages.

The range of pumped fluids is extensive, and the pressures and flows can be configured to suit your exact requirements. From basic chemical injection skids to bespoke packages, our pump systems meet the high standards of specification, quality and reliability required by hazardous area operators.

Pump Package Options

Pump units can be skid, crash frame or container mounted and are generally designed for use in hazardous areas. Many of the chemical injection pump systems we supply have integral storage tanks. With chemical injection skids there are options for environmental enclosures. These enclosures offer your operators and equipment significant levels of protection and, as a result, increased equipment longevity. Options for our environmental enclosures include noise attenuation, heating, lighting, internal maintenance crane, and fire and gas detection systems. We also offer design to account for explosion/blast loads. Additionally, there is a range of options such as variable flows, on-board and remote control capabilities, and electric, hydraulic or pneumatic drive.

Our Chemical Injection Experience

As specialist chemical injection package manufacturers, we design and build chemical injection skids to suit your specific requirements. Whether you seek an ATEX pump package or other industry standard, check out our knowledge and experience of offshore pump skids for hazardous areas.

Compact, Hydraulically Driven CIP

We were approached by Shell to design and manufacture a CIP for a location without a suitable electric supply. For maximum flexibility, we chose a hydraulic system. This consisted of two DNV-certified containers – one housing a hydraulic power pack and the other a high pressure pump. Each unit is compact and, therefore, has a maximum weight of 4,500 kg. The package operates in an ATEX Zone 2 hazardous. Read more about this hydraulically driven CIP.

Hydrate Inhibitor Skid for High Ambient Temperatures

We designed this hydrate inhibitor injection skid to operate in the high ambient temperatures of the Persian Gulf. In order to achieve the operating temperature requirements, we incorporated specialist cooling equipment into the unit. We also fitted a protective enclosure to reduce the heating effect of the sun.

  • Variable flows.
  • Noise attenuation.
  • Local or remote control.
  • Data acquisition and logging.
  • Electric, hydraulic or pneumatic drive.
  • System performance and health monitoring.

Chemical injection packages are usually manufactured for integration into the customer’s existing systems. For this reason, with many of our units we provide a skid-edge panel for connection of controls and electric supply. However, we frequently supply with local or remote control, system performance/health monitoring, and data acquisition and logging.
