Vertical MultiStage Series 4700
Series 4700 pumps, designed for temperatures ranging from 5°F to 250°F (-15°C to 120°C), are well
suited for pressure boosting and boiler feed applications, condensate recovery and air conditioning
systems. Easy to incorporate into industrial environmental engineering equipment, our stainless steel
Vertical MultiStage pumps combine the advantages of compact design, quiet operation and ease of
maintenance.

dualARM Series 4302 and 4382
Armstrong’s dualARM VIL pumps incorporate two Series 4300 or 4380 pumps in a single casing.
The Series 4302 is designed with split spacer couplings so that the mechanical seals can be serv-
iced without disturbing the pump or motor connections. The Series 4302 is available with outside
balanced or inside seals. The Series 4382 is an economical close-coupled design. Both types are
supplied with a swing discharge port in order to hydraulically separate the casings and prevent
recirculation when only one pump operates. Built-in isolation valves enable the isolation of one pump
for service or removal while the second pump remains in operation.
The Armstrong IVS Sensorless pump is designed to meet the need for energy-efficient pumping
systems in today's buildings. Traditional pumping systems incorporating constant-speed pumps
waste energy through crude throttling valve flow control. The IVS Sensorless automatically
adjusts operating speed to match the system load at all times. The resulting energy savings can
pay for the initial cost of the pump in as little as three years.

Pump-in-a-Box (PiB)
The PiB Series builds on the quality and unsurpassed performance customers have come to
expect from Armstrong products. PiB models are packaged for warehouse distribution or
shipment within hours of an order placement. Current PiB models include the 4360 and 4380
Series VIL pumps, available with an extensive selection of impeller and motor
combinations, to cover a wide range of head and flow requirements.
