2 Aurora 0A Series Pumps Reliable Pumping Service Apco regenerative turbine pumps are field-proven throughout the world. Apco pumps are ideal for handling () high head/low flow requirements, () liquids entrained with gases and vapors (up to 0%), and () constant flows. You are assured of reliable pumping service because every Apco is tested to ensure consistent performance. onventional centrifugal pumps, in contrast, must operate close to shutoff or operate at high speed to meet these high head/low flow requirements. These misapplications can cause high vibration, mechanical damage, frequent maintenance, and excessive energy use. Apco pumps thrive in high head/low flow applications so you save on operating costs (less maintenance, downtime and energy costs). 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. 00 Increase System Reliability with onstant Flow Apco pumps assure constant flow when you need it. The steep performance curve allows for minimal changes in the capacity even with large pressure variations. 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. 00 Ft Total ynamic Head - Feet Apco pumps are designed for those special applications where high head and low flow are required by the system. Boiler feed systems, for example, require high pressure to get low flows of water into the pressurized steam boiler apacity - GPM 0 GPM The curve above shows that with a 00 foot change in head, the capacity varies only gallons per minute. You get a virtually constant flow over wide pressure variations to ensure reliable system operation.

6 Engineering Specifications The contractor shall furnish (and install as shown on the plans) an Apco regenerative turbine type pump model size (Bronze Fitted) (Bronze Ring) (All Iron) (All Bronze). Each pump shall have a capacity of GPM when operating at a total head of feet at the specified temperature, viscosity, specific gravity, and NPSH. The speed of the pump shall not exceed 70 RPM. (Models A,,, and can also be operated at 00 RPM.) The pump is to be furnished with (mechanical seals) (packing). The pump shall be of vertically split case design with removable bearing housings, and the channel rings shall be replaceable without replacing the bearing housings. The suction and discharge connections shall be cast integral with the casing. The discharge shall be in a vertical position and the pump shall be self-venting. The casing and bearing housings shall be cast of 0,000 pound tensile strength cast iron. The impeller(s) shall be located on the stainless steel shaft between grease lubricated ball bearings. The impeller shall be hydraulically self-centering and no external adjustment shall be necessary. Each pump shall be tested prior to shipment. The pump shall be mounted on a (steel drip rim) (steel) baseplate and flexibly coupled to a HP phase, hertz, voltage, RPM, horizontal (dripproof) (totally enclosed) (explosion proof) motor. The motor shall be sized to prevent overloading at the highest head condition listed in the specifications.
