Armstrong Pumps

Maddock Industries represents the full line of Armstrong pumps, which provide life cycle value at every turn:

Installation: vertical in-line pumps, being integral components of the pipework, eliminate need for inertia bases, inertia base springs, flexible pipe connectors, field grouting, and alignment.
Space Savings: the greatest floor space savings result when Vertical In-Line pumps are installed with Armstrong Suction Guides and Flo-Trex valves. Equivalent base-mounted, horizontal split case pumps take up to 300% more floor space.
Maintenance: the mechanical seal is the critical service item in any pump. Removal of the Series 4300 split spacer coupling allows all mechanical seal components to be withdrawn for servicing, through the resulting space between pump and motor shafts, without disturbing other pump components or motor connection.
Reliability: dynamically balanced impeller and shaft assembly rotating vertically on the Series 4300 centerline translate to a quiet, long-lasting pump with minimum vibration, as static shaft deflection is eliminated. There are no pump bearings to service in the vertical in-line design. Armstrong Pump Manager also detects potential pump failure before it happens.
