Series 4300 Split Coupled Vertical In-Line

Armstrong's vertical in-line pump represents a design innovation that has repeatedly proven its value over the past 30 years. Armstrong took a leadership role in improving the efficiency and utility of commercial pumps by designing and marketing the vertical in-line pump in the early 1970s. Armstrong takes a leading role in educating engineers around the world on the value of vertical in-line pump installations, and offers one of the widest range of vertical in-line pump sizes in the industry. The Armstrong 4300 split coupled vertical in-line pump includes both a silicon carbide seal and an outside balanced seal as standard items. Armstrong vertical in-line pumps combine excellent operating efficiency, with very low vibration and noise. As well, Armstrong offers a very valuable design/assist program whereby an internal designer will work with contractors and engineers to ‘lay out' and mechanical room using vertical technology. In past instances, substituting vertical pumps for horizontal, in addition to reorganizing and repositioning mechanical room components has led to tremendous cost savings in piping and system efficiency.

IVS and IVS Sensorless Variable Speed Pumps

The Armstrong IVS Sensorless pump is designed to meet the need for energy-efficient pumping systems in today's buildings. Traditional smaller pumping systems, up to and including 10 hp, incorporating fixed-speed pumps waste energy through crude throttling valve flow control. Lifetime Cost Analysis shows that the capital cost of a fixed-speed pump is typically only 5% of its lifetime cost. The IVS Sensorless pump is a new generation variable-speed pump, completely integrated into a compact package. Pressure transducers/sensors are no longer required, which reduces the installed cost of the unit and makes it practical to use these IVS variable-speed pumps in a retrofit installation. Applications for this technology include variable volume heating and chilled water applications. The design of the Armstrong IVS Sensorless pump goes beyond ASHRAE 90.1 standards, providing the benefits of variable speed technology for motor sizes below 10 hp. Variable speed technology allows the speed of the pump to be tuned to suit system demand. Technological advancements make variable speed pumps attractive in terms of both capital and lifetime cost. Pressure transducers/sensors are no longer required, further reducing capital and installation cost. The IVS Sensorless pump is a new generation pump, completely integrated into a compact package. Applications for this technology include variable volume heating and chilled water applications. Goes beyond ASHRAE 90.1 standards by adding value through varying pump speed with 10 hp and lower motor sizes.

Series 4302 and 4382 Vertical In-Line dualArm Pumps

Armstrong’s new dualArm vertical in-line pumps incorporate two Series 4300 or 4380 pumps in a single casing. Series 4302 is designed with split spacer type couplings, so that the mechanical seals may be serviced without disturbing the pump or motor connections, and is available with outside balanced or inside seals. Series 4382 is the economical close coupled design. Each type is supplied with a swing discharge port to hydraulically separate the casings to prevent recirculation when only one pump operates. Isolation valves enable one pump to be isolated for service or removal with the second pump still operating.

Series 4360 and 4380 Close Coupled Vertical In-Line

VERTICAL IN-LINE SERIES 4360 Armstrong’s economical, lower-range vertical inline pump for HVAC, domestic water systems, and industrial applications requiring a compact pump. Positive sealing assured by proven inside-type mechanical seal. Radially split volute permits removal of the motor and pump rotating assembly without removing the pump volute from the line. Fewer maintenance and servicing problems due to bearing-free pump design. Available in bronze fitted, all bronze, or all iron construction, in a range of sizes. VERTICAL IN-LINE SERIES 4380 Armstrong’s close-coupled vertical in-line pump features economical inside-type, single-spring mechanical seal, serviced by removing the rotating assembly while the pump casing remains in the line. Dynamically balanced impeller assures smooth, vibration-free operation. Radially split volute with equal suction and discharge flange sizes. Separate tapped openings for gauge, flush and drain connections. Available in bronze fitted, all bronze, all iron, and ductile iron construction.

Series 4030 and TD40 Base Mounted Pumps

Motor mounted version of the horizontal end suction pump, with flanged connections. Radially-split volute with center-line discharge. Motor features heavy duty, grease-lubricated ball bearings. Supplied with self-lubricating mechanical seal and bronze balanced cast impeller designed for smooth performance and long life. Available in bronze fitted, all bronze and all iron construction.

Series 4600 HSC Horizontal Split Case

The Series 4600 is the state of the art Horizontal Split Case pump – based on the "Tilted Parting" concept to minimize turbulence at the eye of the impeller by its straight laminar approach, thus maximizing efficiency. This also results in the lowest profile and minimum floor space of any HSC pump, lowering installation costs. Cartridge seals and bearing removal nuts ensure ease of maintenance.

Series 4700 Vertical MultiStage Pumps

Environmental Engineering: Armstrong Series 4700, designed for temperatures ranging from 5°F to 250°F (-15°C to 120°C), are well suited for boiler feed applications, condensate recovery and air conditioning systems. Easy to incorporate into industrial environmental engineering equipment, our Vertical MultiStage pumps combine the advantages of compact design, quiet operation and ease of maintenance. Water Distribution: From basic water supply to the most specific pressure boosting and fire line pressure maintenance applications, Armstrong Series 4700 Vertical MultiStage pumps satisfy all water distribution requirements. The wide pressure range - from 10 psig to 430 psig (0.7 bar to 30 bar) - makes this product well suited for applications such as pressure washing of aircraft, trains, boats and road vehicles as well as spray washing of industrial parts and electronic components. Industry: Water feed to machine tools, grease removal, cooling of lathes and molds ... water has many uses in the industrial market. The stainless steel design and wide temperature parameters of the Series 4700 Vertical MultiStage pump makes it an ideal unit for light industrial applications. Water Treatment: Water is becoming a precious commodity. Water transportation, demineralization, filtration, deionization and reverse osmosis all call for high pressure supply and hygienic considerations. The Armstrong Series 4700 Vertical MultiStage pump is made entirely with stainless steel wetted components, for most sizes and is well suited for these applications. Agriculture: The excellent hydraulic efficiency of the Armstrong Series 4700 makes this pump a great choice for irrigation and sprinkling applications. Whether irrigating large farms or sprinkling parks and golf courses, the Armstrong stainless steel pump stages provide the best hydraulic efficiency in all power ranges. The compact design allows the best utilization of available space in pumping stations.
