Armstrongest System Value
Armstrong dualARM Vertical In-Line pumps, when installed with Armstrong Suction Guides
2, result in the greatest added value and lowest life cycle cost of any equipment that can be designed into today's commercial, industrial,
hvac and packaged systems.

The Armstrong Suction Guide, designed with flow stabilizing
plates in the outlet port, allows the guide to be bolted directly
onto the pumpsuction flange, enabling the vertical piping to
turn 90° into the pump. A disposable fine mesh start-up
strainer and permanent perforated stainless steel strainer
complete this valuable fitting.
The Suction Guide eliminates the need for a separate suction
strainer, long radius elbow and minimum straight pipe run to
the pump suction.

and Armstrong Flo-Trex combination valves

The Armstrong Flo-Trex triple function combination valve is
designed to operate equally as a non-slam check valve, drip
tight isolation valve and properly designed throttling valve. The
throttling feature enables a system head increase to operate
the pump at design conditions. The Armstrong uniquely
designed valve is field convertible from 90° angle type to 180°
straight type.
The Flo-Trex combination valve eliminates the need for a
discharge elbow, a separate check valve and a throttling type
isolation valve.
