Design Envelope replaces mechanical components with electronics and software intelligence. The pump can be downsized at selection, runs at its best across part load, and carries its own controls instead of a wall-mounted drive.
Vertical in-line, horizontal end-suction, split-case and multistage. Design Envelope units carry their intelligent controls on board, so there is no wall-mounted drive, no separate transformer and no differential-pressure sensor to wire.
Split-coupled twin pump on one casing. Two rotating assemblies share a single pipe drop, so one can be removed for service while the other carries 75–100% of flow.
Close-coupled Tango with duty/standby operation. The compact option where plant room height is tight.
Split-coupled twin unit for duty/standby or parallel pumping. The larger sibling of Tango, where the duty exceeds 7.5 kW.
Close-coupled twin unit with the same parallel-pumping control.
The workhorse vertical in-line. A UL 778 pumping unit with integrated controls, spanning almost the whole commercial range.
Close-coupled vertical in-line for space-saving installation on smaller duties.
Base-mounted end-suction horizontal with integrated intelligent controls, for plant rooms where a horizontal set is specified.
Motor-mounted horizontal unit with integrated controls for space-saving installation.
Permanent-magnet motor on a single-phase supply, for light commercial duties.
Split-coupled twin unit for duty/standby, without on-board controls.
Close-coupled twin unit for duty/standby operation.
Close-coupled pipe-mounted pump built for long service life on small duties.
NEMA-premium motors on a base-mounted end-suction frame, reducing cost across installation, operation and lifetime maintenance.
End-suction pump close-coupled to the motor to minimise footprint.
Close-coupled horizontal pump designed for long service life and easy maintenance.
High head from a small footprint, designed for reliability and low maintenance cost.
Large-duty split-case pump with high-efficiency NEMA-premium motors.
Multiple-pump boosting sets with intelligent staging, automatic set-point adjustment and integrated variable frequency drives. Available in lead-free versions meeting potable water standards.
An all-purpose set for higher flowrates and boost pressures. Multiple pump configurations keep design and commissioning flexible.
Permanent-magnet motors with Design Envelope control. Higher efficiency, lower noise.
The compact option for small and medium buildings, with the smallest footprint in its class.
Hydronic circulators for heating, cooling and domestic hot water, in flange-to-flange dimensions that replace most installed models without repiping.
Wet rotor circulator built to replace existing fixed-speed units. Cast iron and stainless steel volutes.
Dry rotor circulator; a universal replacement across its capacity range.
Advanced motor technology and efficient hydraulic design for excellent wire-to-water duty point efficiency.
Circulates water or ethylene-glycol in closed hydronic and solar heating systems. Two volute materials available.
For commercial systems needing higher flow and pressure, with a customisable flow curve.
Commercial three-piece circulator with the flexibility to tune the curve to the application.
A complete repair solution for the S&H line, and for rebuilding or upgrading selected competing models.
Circulator and low-flow valve combined, giving instant hot water in a residential plumbing system.
Plate heat exchangers save up to 75% of the floor area and up to 85% of the floor length a shell and tube unit needs, including the space required to service it.
Gasketed plate units optimised for water-to-water transfer. True counter-current flow lets the unit work at very low temperature approaches, with regeneration rates to 90%.
Designed for use with agitated or non-agitated tanks.
Constructed, tested and certified to NFPA, UL, ULC and FM. Available as single electric, single diesel, one electric plus one diesel, two electric or two diesel configurations.
The full range of HSC fire pumps, electric or diesel driven, with controller. Mounted, piped and wired on a base at the factory.
Complete VIL package with electric motor and controller, designed to fit through a standard door.
The vertical arrangement saves up to 60% of the floor space an equivalent horizontal split-case set needs.
Factory-built integrated unit of pump, driver and variable speed control, holding the set pressure until maximum power draw.
The pressure-maintenance pump for a fire system.
The ancillary items that decide whether a well-specified plant room actually performs, and the usual source of low points and operating bottlenecks when they are left out.
A 90° elbow, guide vanes and an in-line strainer in one body, cutting installation cost and floor space.
Removes trapped air and suspended dirt associated with the start-up and maintenance of hydronic and HVAC systems.
Plain steel, diaphragm and bladder types, reducing tank size by up to 80% over standard designs.
Automatic glycol make-up with a moulded mixing tank, built-in controls housing and make-up pump.
Multi-turn adjustment for precise control, with hidden memory stops and soft seats for positive shutoff.
A Tango twin replaces a conventional duty/standby pair. Measured against a standard end-suction horizontal duty/standby configuration, the difference on a single installation is not marginal.
| Total pump weight | 811.9 kg → 86.6 kg 89% lighter |
|---|---|
| Installation weight | 1198.4 kg → 322.9 kg 73% lighter |
| Installation footprint | 1.12 m² → 0.46 m² 81% smaller |
| Five-year lifecycle cost | Between 23% and 33% lower, depending on the redundancy configuration selected |
Figures published by Armstrong Fluid Technology, comparing Design Envelope Tango against a standard end-suction horizontal duty/standby configuration. Actual results depend on duty, tariff and installation.
Stainless steel and titanium plates, each stamped with an optimised corrugation. Alternating channels carry the process and service fluids in true counter-current flow, so the unit performs at very low temperature approaches.
| Flow range | Up to 32,000 gpm (2000 L/s) |
|---|---|
| Duty | Up to 57,000,000 btu/hr (16,700 kW) |
| Max working pressure | 435 psi (2999 kPa, 30 bar) |
| Max fluid temperature | 284°F (140°C) nitrile gaskets; 302°F (150°C) EPDM standard; 356°F (180°C) EPDM for steam |
| Plates | 304 and 316 stainless steel, titanium |
| Gaskets | Nitrile, EPDM, Viton |
| Certification | ASME, PED, CRN and NSF 61 for safety; AHRI for performance |
Where a project needs more than components, Armstrong builds the plant room off site and Meptura connects it: modular plant rooms, central utility plants, intelligent fluid management systems and fire pump houses.
Pre-fabricated chiller and boiler plants, pumping stations, energy transfer stations and fire pump houses. The maximum share of work is completed in the factory, so all that remains on site is the connection.
Built-in Wi-Fi gives real-time operating insight and early diagnostic warnings, full transparency on energy saving, and predictive maintenance that can cut pump maintenance cost by up to half.
Lifts the efficiency of new and existing chiller plants to class-leading levels, controlling up to five chillers and five pumps, and integrating with any brand of chiller, pump or building automation system.
