Aurora

Aurora is a Pentair brand of centrifugal pumps, and Aurora Pump is based in North Aurora, Illinois. Its end suction, in-line and split case pumps serve commercial, HVAC, industrial and municipal systems, and in boiler rooms they move condensate, boiler feed water and heating water.

BoilerSupplies.com lists the Aurora 321 and 341A horizontal close coupled end suction pumps, the 323 vertical close coupled pump and the 324A flexible coupled pump. The 326A is an in-line centrifugal and the 411 a horizontal split case. The 412 is a vertical single stage pump, with the 413 and the 3801 Series single stage pumps beside it. Close coupled means the impeller sits on the motor shaft. Flexible coupled means a coupling joins pump and motor, so either one can come off alone. A split case opens along its casing for service. Mechanical seal kits and shaft sleeves are listed by series: 321, 323, 324A and 326A; 340 and 382A; and 3800. BoilerSupplies.com also lists Aurora Replacement Condensate and Boiler Feed Pumps.

How do centrifugal, close coupled and base mounted apply to an Aurora end suction pump?

An Aurora end suction pump is a centrifugal pump, and close coupled or base mounted says how its motor is attached. Water comes in on the end and leaves from the top. Close coupled means the impeller rides on the motor shaft, as on the 321, 323 and 341A. Base mounted usually means flexible coupled on a frame, as with the 324A.

What does a drip at the shaft of an Aurora pump mean?

A drip at the shaft usually means the mechanical seal is leaking, and the seal kit and shaft sleeve are the repair parts for it. Order the kit by the series on the pump nameplate: 321, 323, 324A and 326A; 340 and 382A; or 3800.

What should a quote request for an Aurora pump or seal kit include?

Both nameplates. From the pump plate: model, size and serial number. From the motor plate: horsepower, speed, voltage, phase and frame. For a seal kit the series number leads, and the rest confirms it. A clear photo of each plate, sent to BoilerSupplies.com, covers it.

How does the Aurora 411 split case differ from the 3801 Series end suction pump?

The Aurora 411 is a horizontal split case pump: its casing splits along the shaft line, so the rotating parts lift out for service. The 3801 Series is a single stage end suction pump, taking water in on the end. The choice follows what is on the base and in the piping now, so match the old nameplate.
