4300

Best Commercial HVAC Pump DesignAvailable Since 1969

INSTALLATIONVertical In-Line pumps, being integral components of the pipework, eliminate need for inertia bases, inertia base springs, flexiblepipe connectors, field grouting and alignment. Pipe hangers sized for the weight of pump, piping and fittings are the onlysupports required. Pipe stools, with vibration isolating pads, may be installed under each pipe leg.

SPACE SAVINGGreatest floor space savings result when Vertical In-Line pumps are installed with Armstrong Suction Guides and Flo-Trexvalves. Equivalent base mounted, horizontal split case pumps may take 3 times more floor space.

MAINTENANCEThe mechanical seal is the critical service item in any pump. Removal of the Series 4300 split spacer coupling allows allmechanical seal components to be withdrawn for servicing, through the resulting space between pump and motor shafts,without disturbing other pump components or motor connection.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 rotatingassembly back to factory alignment specifications.

RELIABILITYDynamically 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 theVertical In-Line design. Series 4300 is a reliable, time-proven unit with less down time.

FLEXIBILITYSmall 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.

Life Cycle Value at Every Turn:

Split Coupled

1 Industry standard motor designed for Vertical In-Lineoperation.

2 Heavy cylindrical bracket with 360° register on eachflange provides a rigid union of pump and motor.

3 Motor shaft run-out limited to 0.001” (0.025 mm) TIR(Total Indicator Reading).

Split CoupledThe axially split, spacer type rigid coupling permits seal maintenance without disturbing the pump or motor connections.The mechanical seal is accessible and easily replaced. (Outside multi-spring balanced mechanical seal is illustrated).

Sealing ArrangementsArmstrong series 4300 split coupled Vertical In-Line pumps are available with two mechanical seal arrangements. Both canbe removed easily and quickly for servicing without costly removal of the motor or pump from the piping. The highperformance outside type mechanical seal combines the advantages of a multi-spring balanced seal with premium qualityand is the easiest to remove. The inside type mechanical seal provides an economical alternative.

1) Split coupling with outside seal. Axially splitcoupling shown with coupling guard removed.Coupling bolts are still in place. Rotatingelement of seal is seen below the coupling,above gland plate.

3) Disconnect seal flush line and remove glandplate bolts. The gland plate and seal seat maythen be taken out between the space in theshafts. With inside seal the complete seal isremoved following the gland plate.

4) New Seal may now be installed. Reversethe procedure: Install new seal, replace glandplate, replace coupling and restart pump.Rigid coupling retains factory alignment.

2) Remove the coupling bolts. The couplinghalves (with drive and annular positioning keys)are taken from motor and pump shafts. Loosenset screws on seal rotating element and slidefrom pump shaft. (For inside seal see step 3)

Armstrong takes you back to the future with the Series 4600 Horizontal Split Case (HSC) Pump for HVAC and industrial applications.

The Series 4600, drawing on over 100 years of pump design expertise and leadership, is the state of the art in HSC pumps. It meets or exceeds the requirements of its intended market applications.

This Family of pumps capitalize on the “Tilted Part-ing” concept to minimize turbulence at the eye of the impeller by its straight laminar approach, thus maxi-mizing efficiency. This also results in the lowest profile and minimum floor space of any HSC pump on the market today. The family was designed with com-monality of parts, low installation costs, and ease of maintenance objectives.

Vertical In-Line Pump

Base mounted pump with Suction Guide and

Flo-Trex valve eliminates cost and space of:

Suction: • Y-strainer

• Long radius elbow

• Min. straight pipe run.

Discharge: • Check valve

• Isolating valve

• Throttling valve

Vertical In-Line with Suction Guide and Flo-

Trex valve eliminates cost and space of all

the items listed under base mounted pump,

plus the following:

• Inertia base with spring mounts

• Long radius elbow

• Flexible pipe connectors

• Grouting

• Field alignment

• Split couplings available for ease of

mechanical seal replacement

dualARM Vertical In-Line incorporates two

pumps in a casing with single inlet and outlet

connections. Enables standby or parallel

operation with only one set of piping. Casing

design and port valves allow one pump to be

removed for service with the second pump

still operating. When installed with a Suction

Guide and Flo-Trex valve the dualARM

represents the greatest Life Cycle Value in

today’s commercial hvac market.

dualARM Vertical In-Line Pumps FILE NO: 43d.12

DATE: jan 05, 2012

SUPERSEDES: 43d.12

DATE: feb. 10, 2011

• Armstrong Vertical In-Line pump, the best design for hvac

systems, introduced in 1969.

• Armstrong dualARM Vertical In-Line pump, introduced in 1994.

• dualARM Series 4302 & 4382 contain all the features and

advantages of two Armstrong time proven Vertical In-Line pumps,

in one casing.

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.

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.

Pump Checks and Installation3.1 Always check to make sure pump was not damaged in shipment before accepting delivery. If

damage is evident, a claim should be filed with the carrier at that time.

3.2 Always check the pump label against the requirement to make sure you are installing the properpump specified for the job.

3.3 Make sure that the pump suction, marked by a sticker, is connected to the liquid source andthat the discharge, similarly marked, is connected to the discharge line.

! CAUTION

On three phase motor installations, always check for proper motor rotation prior to starting byjogging the motor. Shaft rotation must turn clockwise when viewed from the top of the motor.

Make sure the motor is correctly wired, refer to instructions on motor name plate.
