Armstrong Fluid Technology is one of the leading development fluid-slow solutions. The company has developed itself around products mainly for customers in commercial, residential and industrial arcades.

Armstrong manufactures hydraulic equipment for the above-discussed arcades and applications. They manufacture equipment such as pumps, controls, motors, and some parts are even renowned, for longevity. And their additional product offer equipment such mainly for commercial purposes such as valves, fittings, suction, pressure booster systems, and so on.

They even offer several types of valves in order to foil their centrifugal pump lines, which include circuit balancing valves and Flo-Trex triple duty valves. Apart from valves, Armstrong fluid technology provides a wide range of suction diffusers in a multiplicity of sizes, especially, for HVAC systems, and industrial pumping. These suction diffusers come with a multi-function pump fittings which provides a 90° elbow, guide vanes, and an in-line strainer.


  • In-line pumps eliminate the need for inertia bases and springs.
  • Pipe stools with isolating vibrating pads are installed under each leg of the pipe such as flexible pipe connectors, field grouting, and alignment.


The mechanical seal acts as the critical service object in a pump, and removal of series such as series 4300, 4360 allows all mechanical seat components to be withdrawn easily for servicing and resulting in an additional space between the pump and motor shafts. Space does not disturb the other pump components or motor connection.


Re-installing the rigid coupling brings back the unit rotating assembly to all the factory alignment specifications.


  • They have a small footprint.
  • Comes with low installation costs.
  • Are reliable
  • And easy to maintain and control
