AquFlow 2000 - Diaphragm Metering Pump


224GPH + High PSI + Highly Accurate

S2000 - AquFlow Metering PumpsThe AquFlow Series 2000 diaphragm chemical pump is a rugged, compact hydraulically actuated diaphragm metering pump. It’s designed to handle pressures of up to 1800 PSI and flow capacities up to 180 GPH.

The Series 2000 diaphragm metering pump is available in simplex and duplex configurations, depending on the flow capacity needed. Its robust, modular design enables it to be used in challenging applications in a variety of industries, including municipal water treatment.

All of the Series 2000 chemical injection pumps drive parts are fully enclosed in an aluminum housing. This robust and durable design protects the most important parts from harsh environments while still being capable of handling corrosive dosing chemicals and viscous liquids. Its dependability allows it to operate for years with little maintenance. The AquFlow Series 2000 diaphragm dosing pump durability and efficiency continues to set the standard for chemical metering pumps. Complies with API 675 standards for positive displacement pumps.

Capacity Control Options

  • Dual Axis with both stroke length and stroke speed adjustable.


Stroke Length Controls

  • Manual: Standard on all pumps.
  • Electric: Electric stepper motor. Capable of 4-20mA input.
  • Pneumatic: Runs on 30 PSI air for hazardous environment.


Liquid Handling Options:


  • For liquids with suspended solids/slurries that may clog. Good for high viscosity liquids also.


Degassing Valve

  • Some challenging liquids can cause air locking due to off gassing. Our pump head with degassing valve ensures accurate and consistent pumping by letting our gas bubbles from the pump head.


Double Ball Check Valve

  • An added measure of assurance that you have the position valve shut off.


Tungsten Carbide Valve Balls

  • For abrasive liquids.


Leak Detection Options:

Leak Detection

  • There are two types of leak detection options available with AquFlow pumps.



  • Conductivity probe between 2 diaphragms to sense any break or rupture.



  • Uses a vacuum switch between 2 diaphragms to sense any rupture or failure.


Other Options:

Liquid Connections



Motor Options

  • Enclosure: TEFC, TENV, Explosion Proof, Washdown
  • Power Supply: ACV 115V, 230V, 380V, 460V, DC-12, 24, 90, 180, Single Phase, 3-Phase
