One and Two Stage Regenerative Turbine Pumps

Product catalog summary

Overview: The AURORA® 120B Series “APCO” pumps are one and two-stage turbine type pumps designed for high head and low flow applications. They are suitable for handling liquids with gases and vapors up to 20% and are field-proven globally.

Specifications: These pumps offer capacities up to 50 GPM, heads up to 920 feet, and can handle temperatures up to 275°F. They are designed to operate efficiently in high head/low flow scenarios, reducing energy consumption and maintenance costs.

Applications: The pumps are ideal for boiler feed, condensate return, cooling systems, high-pressure spray, booster systems, chlorine injection, chemical feed systems, laundry and dry cleaning systems, laser cooling, electrostatic discharge machines, TV tube and CRT manufacturing, and car washes.

Benefits: Key benefits include reliability, reduced energy consumption, trouble-free operation, high performance, space-saving design, versatility, and comprehensive technical support.

Performance and Features: The pumps maintain constant flow despite pressure variations, making them suitable for cooling systems. They offer a broad hydraulic coverage with capacities over 50 GPM and up to 920 feet Total Dynamic Head. Standard features include bronze-fitted construction, hydraulically balanced bronze impeller, regreaseable ball bearings, and a 400# case working pressure. Optional features include all-iron construction, 316 stainless steel or Monel™ shaft, and self-priming features.

Engineering Specifications: The pumps are designed with a vertically split case, removable bearing housings, and replaceable channel rings. They are tested prior to shipment and can be mounted on a steel baseplate, flexibly coupled to a motor.

Design Details: The pumps are constructed with materials such as cast iron for casing and channel rings, bronze for impellers, and stainless steel for shafts. They have a maximum hydrostatic test pressure of 600 psi and a maximum case working pressure of 400 psi.

Limitations: The maximum recommended packing box pressure is 100 psi, and the mechanical seal chamber pressure is 250 psi. The maximum temperatures for standard mechanical seals are 225°F, while high-temperature mechanical seals can handle up to 275°F.

One and Two Stage Regenerative Turbine Pumps-3

ONE AND TWO STAGE TURBINE TYPE PUMPS Pump Performance Increase System Reliability. The constant flow characteristics make the Apco ideal for cooling systems where it is vital that sufficient flow is maintained to dissipate heat despite changes in pressure. Pressure variations occur for a number of reasons. The most common designed-in variations are caused by automatic pop-off valves and similar control devices. With Apco pumps, you can always depend on the same capacity despite variations in head pressure and achieve increased system reliability. The Apco pump line has the highest performance...
