Wolverine Electric Chemical Injection Pump

Hazardous Location Chemical Pump – AC and DC Operated

Hazardous location chemical pump with explosion proof chemical pump motors designed to operate in applications requiring Class 1, Division 1 rated products.

The Wolverine hazardous location chemical injection pump is designed to inject chemicals at well sites and pipelines in order to aid in protection from corrosion, plugging and freezing. Utilizing explosion proof motors, these pumps are designed for use in applications requiring Class 1, Division 1 rated products.

  • Easily integrated with Graco chemical injection solar powered systems.
  • Wolverine pumps reduce emissions to the atmosphere and have a greater level of control when used with our injection rate controllers.
  • Each pump features an adjustable fluid packing that lasts up to 25 times longer than non-adjustable seals.
  • All Wolverine pumps have 316 SST wetted parts, plus they are resistant against water and dust.
  • The AC and DC operated motors are rated for use in Division 1 Hazardous (Classified) Locations.
  • Flow rates up to 320 gpd (1,211 lpd) and a pressure rating up to 10,000 psi (686 bar, 68.9 MPa).
  • Long lasting seals can easily be replaced in less than ten minutes, on location.
  • Precision stroke adjustment between ½ in to 1 in (12.7 mm to 25.4 mm) ensures accurate injection rates.
  • HNBR, FKN, FKM ETP, and FFKM plunger packings and check valve seals can handle some of the most aggressive chemicals.
  • Low friction drivetrain to optimize electrical efficiency, reducing the load on your power system.
