Description
Benefits & Features
Low installed cost
- Vertical In-Line design eliminates the need for inertia bases, housekeeping pads, flex connectors, and field alignment or grouting requirements.
- Vertical In-line design minimizes space and pipe requirements.
- Design Envelope selections frequently recommend a smaller motor and/or pump which reduces installed cost.
Low energy consumption
- Armstrong 4380 pumps are equipped with high-efficiency NEMA-premium motors for significant reduction in energy consumption and cost.
- All motors are suitable for inverter-fed service.
- Vertical In-line design minimizes pipe requirements and related friction losses resulting in higher system efficiency.
Low operating risk
- Universal replacement seals, bearings, and motors available locally world-wide.
- Vertical In-Line configuration allows less disruptive pump service. (casing stays in place)

Armstrong Expansion Tanks
- Applications-Pressure stabilization in water based mechanical systems such as booster installations, boiler systems, and chiller plants
- Description-Armstrong Expansion Tanks are designed to reduce tank sizes by up to 80% over standard designs. Expansion tanks use compressed air to maintain system pressures by accepting and expelling the changing volume of water as it heats and cools. Diaphragm or bladder tank designs isolate the expanded water from the pressure controlling air cushion – which is pre-charged at the factory and can be adjusted in the field to meet final system requirements
- Materials (MOC)-Carbon steel (shell), heavy duty Butyl (diaphragm)
- Performance range-AET plain steel expansion tanks: 15 to 525 USgpm flow.
AX diaphragm expansion tanks: 8 to 211 USgpm flow.
Type L bladder type expansion tanks: 10 to 1056 USgpm flow.

Armstrong Vortex Air Separators
- Applications-Air removal from hydronic and HVAC systems – air can get trapped during initial fill, during routine equipment maintenance (including pressure upkeep), and due to the use of cooling towers.
- Description-The Armstrong vortex air separators create a vortex or whirlpool action, sending the heavier air-free water to the outer portion of the tank, and allowing the lighter air-entrained water mixture to move into the lower-velocity center. At the center of the vortex the air is released from the water, forms bubbles and exits through an air vent or compression tank installed above it.
- Materials (MOC)-Cast iron or fabricated steel (shell), stainless steel mesh (strainer)
