5 Series 4300 Split Coupled Vertical In-Line Pumps FILE NO: DATE: Sept. 12, 2007 SUPERSEDES: DATE: Mar. 1, 2007

6 Series 4300 Best Commercial HVAC Pump Design Available Since 1969 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. Pipe hangers sized for the weight of pump, piping and fittings are the only supports required. Pipe stools, with vibration isolating pads, may be installed under each pipe leg. SPACE SAVING 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 may take 3 times 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 Removal of the Series 4300 split spacer coupling allows all mechanical seal components to be withdrawn for servicing, through the resulting space between pump and motor shafts, without disturbing other pump components or motor connection. Re-installing the rigid coupling brings the unit rotating assembly back to factory alignment specifications. 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. Series 4300 is a reliable, time-proven unit with less down time. FLEXIBILITY Small footprint, low installation costs, reliable and easy to maintain. These features, combined with flow range in excess of 30,000 USgpm (1,900 L/s), affirms the Series 4300 as the most flexible pump design available.

30 Series 4302 & 4382 dualarm Vertical In-Line Pumps FILE NO: 43d.12 DATE: jan 05, 2012 SUPERSEDES: 43d.12 DATE: feb. 10, 2011

31 Series 4302 & 4382 Smart pumps for the commercial hvac market. Armstrong Vertical In-Line pump, the best design for hvac systems, introduced in Armstrong dualarm Vertical In-Line pump, introduced in dualarm Series 4302 & 4382 contain all the features and advantages of two Armstrong time proven Vertical In-Line pumps, in one casing. Series 4302, shown with one guard removed to reveal outside balanced seal, and a cutaway to show the isolation valve. Adding Value to Hydronic Systems Floor Space Value: In a typical system, for example 1000 USgpm flow at 50 ft head (63.1 L/s at 15.2 m), the dualarm needs only one quarter of the space required for two end suction base mounted pumps and one eighth the space required for two split case horizontal pumps. Installation Value: Vertical In-Line pumps become an integral component of the piping system. This configuration eliminates the need for flexible connectors, inertia bases, grouting and field alignment. Maintenance Value: Mechanical seals require the greatest amount of maintenance in any pump. Service is performed on any Vertical In-Line pump without removing the casing from the piping. The Series 4302 split-spacer coupling design allows the mechanical seals to be serviced without disturbing the pump or motor connections. System Value: Standby and parallel pump systems may now be designed using only one pump piping set. Two pumps in a single large port casing allow both pumps to operate simultaneously, in true parallel fashion, with no loss in single pump efficiency. Design Value: dualarm Vertical In-Line pumps, designed with a swing split-flapper valve in the discharge port, prevent liquid recirculating when only one pump is operating. Unique Armstrong isolation valves allow one pump to be isolated and removed for service while the second pump remains in operation.

32 dualarm Vertic al In-Line Pumps Series 4302 Designed to incorporate two Armstrong standard Series 4300 split coupled Vertical In-Line pumps in a single casing.

35 Armstrongest System Value Armstrong dualarm Vertical In-Line pumps, when installed with Armstrong Suction Guides 1 and Armstrong Flo-Trex combination valves 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. 1 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. 2 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. 2 armstrong flo-trex combination valve 1 armstrong suction guide armstrong dualarm vertical in-line pump
