Pneumatically Driven Chemical Injection Pump

Product Details

The Bruin BR6000 Chemical Injector Pump is a single acting, positive displacement plunger type barrel pump. Powered by pneumatic pressure acting against a piston, equipped with a spring return and standalone timer. The BR6000 can produce output volumes up to 204.2 Litres per day with a 1/2” plunger and discharge pressures up to 3000 psig with a 1/4” plunger. Volume is controlled based on plunger size, stroke length selection, and the speed of the pump via a timer. Maximum discharge pressure capability is governed by the seal selection and discharge pressure can be controlled with the supply pressure via a regulator.


  • Adjustable speed (0 – 45 spm) and plunger sizes (1/4” & 1/2”) provide an adjustable volume output up to 204.2 Litres per day maximum.
  • Stand alone stainless steel timer.
  • Threaded exhaust ports.
  • Double sealing arrangement with lubrication chamber.
  • Bleeder equipped with barbed fitting for tubing.
  • Discharge and suction check valves incorporate TFE seals.
  • Stainless steel construction.
  • Hardened 17-4 PH stainless steel seats.
  • Designed for ease of operation and maintenance under varied pumping applications.
