BR5100

Pneumatically Driven Chemical Injection Pump

Product Details

The Bruin BR5100 Chemical Injector Pump is a single acting, positive displacement plunger type pump. Equipped with a spring return, automatic switching mechanism and powered by pneumatic pressure acting against a diaphragm, it is capable of operation with supply pressures as low as 2 psig (35 psig max.) and available in 4 plunger sizes. The BR5100 can handle output volumes up to 137 Litres per day with a 1/2” head and discharge pressures up to 6000 psig with a 3/16” head. Volume is controlled based on plunger size, the stroke length selection and the speed of the pump via a speed control valve. Maximum discharge capability is governed by the packing selection, and discharge pressure can be controlled with the supply pressure via a regulator.

Highlights

  • Adjustable speed (0 – 30 spm) and plunger sizes (3/16″, 1/4″, 3/8″ & 1/2″) provide an adjustable volume output up to 137 Litres per day maximum.
  • Air distribution system provides greater control of the stroke rate and injection rate without stalling.
  • Micro Switch system provides oilless operation.
  • Contoured diaphragm plate improves diaphragm life.
  • Clear acrylic lid for easy inspection of pump internals.
  • Low supply pressure model allows for operation with pressures as low as 2 psig (dependant on discharge pressure and pump set up).
  • Low volume model allows for variable stroke length adjustment.
  • Conversion for handling of various chemicals is easily accomplished by the change out of the packing set and fluid end seals.
