They are also used in industrial complexes for returning liquids to overhead storage tanks of gravitational circulating systems as well as many other unique uses. CONDENSATE return requirements call for a system that will provide uninterrupted service for single or multiple boiler installations. AURORA packaged systems deliver those values that you need and expect. Quality features include a steel receiver, float switch and pumps all completely assembled. In AURORA s design, the pumps , support and piping are mounted beneath the receiver on a common steel base.

2 As your heating system grows, the receiver design will allow you to convert from simplex to duplex. Just add a pump and pipe it up! In a duplex system, single pump operation provides service when capacity and demand call for normal service. Duplex units require very little additional floor space than a simplex unit requires. The two APCO pumps used in the system operate alternately to extend the life of both pumps . Both pumps operate simultaneously when service demands exceed the capabilities of a single pump. This AURORA product offers: Turbine design that handles vapor bubbles with no vapor lock. Design simplicity with a minimum of parts. Complete system package prepiped on a one-piece common base. Versatile, rugged, compact construction.

More pressure is developed within the turbine pump than with a comparable size centrifugal pump. The pumped liquid is directed by the water passage so that it circulates in and out of the buckets many times on its way from the pump inlet to the pump outlet.

5 Additional energy is added to the liquid each time it passes through the buckets so the numerous passes generate a high discharge pressure. The pressure is developed without pulsations. While close clearances are used within the turbine pumps , there is no metal-to-metal contact. Volatile liquids are handled easily because a turbine pump readily handles vapor and air along with the liquid, thus eliminating the possibility of a vapor lock within the pump. Free-flowing and nonlubricating liquids are handled with a minimum of wear to pump parts because there is no metal-to-metal contact within the pump channel. The illustrations indicate the principle used in the handling of the liquid and developing of pressure in a regenerative turbine AND TWO STAGE CONDENSATE PUMPSPump Operation and FeaturesGauge Glass Guards Optional Galvanized Tank OptionalAurora APCO Turbine Pump Features Double suction minimizes axial thrust.

Seals are optionally available on single as well as two STAGE pumps . Large shaft for minimum deflections. Slingers protect bearings. O-rings prevent StartersMagnetic starters with overload and under-voltage protection are conveniently mounted on the unit. The starters are wired to the pump motors and to the float switch or combination float switch and alternator. Rated for three phase, 1/3 hp and larger; and single phase, 1 hp and larger. (Starters not required on single phase, hp motors or less.) On simplex units, the starter is mounted in a general purpose enclosure. On duplex units, magnetic starters are panel mounted in a NEMA 1 enclosure. Reset buttons are provided outside the starter enclosure for easy operation and AND TWO STAGE CONDENSATE PUMPSPump FeaturesA.

7 Steel Receiver is 3/16" thick to ensure long life. Receiver connections are threaded and include vent, inlet and Stainless Steel Float has adjustable travel to permit 1-1/2 times maximum return rate between stops. Combination float switch and alternator is standard on duplex Temperatures to 190 F water and selected for a minimum capacity of twice the rate of Brass Water Level Gauge glass assembly is furnished complete with shut-off Interchangeable Design provides future system expansion with receiver connections for up to two pumps . Just add a pump and pipe it Completely Assembled Piping from receiver to pump. Included are expansion type elbows to eliminate pipe Accessibility to pump and other components for easier maintenance. All pumps and piping are mounted beneath the receiver.
