Diaphragm water-driven chemical injector

The Chemilizer is a proportional liquid chemical injector that injects a precise amount of chemical in proportion to a volume of water. The Chemilizer is an industry-leading chemical injector that utilizes years of proven diaphragm technology.

Powered by the existing water supply, it can run off water flows as low as 4L per hour and will work with gravity via as little as 1.5m. head of water. The speed of the motor and pump are proportional to the water flow, ensuring Chemilizer will inject consistent amounts of chemical regardless of fluctuation in water pressure and flow.

Chemilizer injectors are ideal for applications requiring a consistent level of chemical product to be injected into a water line, without the cost and hassle of an electric pump or filter.

  • Chemilizer injectors are immune to electrical surge and power failure due to their water-powered motors
  • Work with any water source – The diaphragm water motor is unaffected by sand or minerals in the water
  • Chemical resistant – The chemical is injected after the motor, avoiding contact with critical motor parts
  • Tailored to your specific dilution needs – Six dilution rations available
  • Easy and low cost maintenance
