Feed requirements of boilers demand a system that produces non-stop service for single or double boiler installations. These Aurora boiler feed units get the job done.

  • Capacities to 77 G.P.M. (17.5 M3/HR)
  • Heads to 678 Feet (176 Meters)
  • Temperatures to 210ºF (107ºC)


Quality features include a carbon steel receiver, 3-way valves, and pumps, all completely assembled. Duplex, dual and triplex units do not require any additional floor space than a simplex unit requires. In Aurora's design, the pumps, bases and piping are mounted beneath the receiver within the support stand. As your heating system grows, the receiver design will allow you to convert from simplex to duplex, dual or triplex construction. Just add pumps and pipe them up! The following pages explain the reasons why AURORA PUMP is able to offer you a modern, packaged, customer proven, feed system.

  1. CARBON STEEL RECEIVER is 3/16" thick to insure long life. Receivers include 2 vents, 2 inlets, drain and connections for additional optional equipment.
  2. BRASS FLOAT VALVE with simple lever action replaces water lost due to processing, etc.
  3. TEMPERATURES TO 210ºF water and selected for a minimum capacity of twice the rate of evaporation.
  4. BRASS WATER LEVEL GAUGE glass assembly is furnished complete with shut-off valve and protector rods.
  5. INTERCHANGEABLE DESIGN provides future system expansion with receiver connections for up to 3 pumps. Just add pumps and pipe them up.
  6. 3-WAY VALVE provides dependable operation. With a turn of the plug the water flow can be channeled through the strainer or by-passed around the strainer (to allow the strainer to be cleaned), or completely shut off.
  7. COMPLETELY ASSEMBLED PIPING from receiver to pump. Included are expansion type elbows.
  8. ACCESSIBILITY to pump, strainer valve and other components for easier maintenance. All pumps and piping are mounted beneath the receiver within the support stand.
  9. PUMPS designed for boiler feed applications will handle entrained vapor and air with liquid to eliminate vapor lock.
  10. THERMOMETER provides readings from 40ºF to 260ºF.

Operation - Turbine Pumps

N/A

The turbine pump derives its name from the many buckets machined into the periphery of the rotating impeller which permits development of a relatively high pressure in an efficient and economic manner. 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. 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 non-lubricating 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 pump.

  • Double suction minimizes axial thrust.
  • Replaceable channel or wearing rings and impellers.
  • Opposed discharges to balance radial loads (two stage).
  • Interchangeable packing or mechanical seals.
  • Large shaft for minimum deflections.
  • O-rings prevent case leakage on One/Two Stage Turbine Pumps.
