Aurora Regenerative Turbine Pumps
By Flow-Tech Industries

Aurora offers regenerative turbine pumps, including the 110A Series “Apco” and the 150 Series “Apco-Chem.”

Turbine pumps have long since been recognized for their effectiveness in low-flow, high-head applications. They offer higher heads than centrifugal pumps.

Because the head capacity curve is steep in a turbine pump, a greater degree of flexibility is available to the process engineer. Turbine pumps having top centerline discharge are self-venting and have the ability to handle vapors without vapor lock. This characteristic allows handling of boiling liquids and liquefied gases at suction heads slightly over the vapor pressure.

Turbine pumps also have higher efficiencies at low flows than a centrifugal pump.

They utilize close running clearances and are normally utilized on clean-liquid applications. Viscous materials up to 500 S.S.U. can be pumped.

110A Series “Apco” Pumps
One- and Two-Stage Turbine Type Pumps

110A Series regenerative turbine pumps are field-proven throughout the world. They are ideal for handling: (1) high-head/low-flow requirements, (2) liquids entrained with gases and vapors (up to 20%) and (3) constant flows.

You are assured of reliable pumping service because every pump is tested to insure consistent performance.

110A 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.

Conventional centrifugal pumps, in contrast, must operate close to shut off 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.
110A pumps thrive in high-head/low-flow applications so you save on operating costs (less maintenance, downtime and energy costs).

 

150 Series “Apco-Chem” Pumps
For Low-Flow, High-Pressure Applications

Design Features:

• Steep head-capacity curves for applications that require minimal flow change.
• Ability to handle vapors up to 20% by volume.
• Steady flow - eliminates pulsation problems associated with other pump designs.
• Back pull-out design for low-cost, one-craft maintenance.
• Top vertical centerline discharge.
• Pump has known shut-off pressure as opposed to positive displacement designs.
• Reduced downtime for bearing and seal maintenance.
• Pump built to ANSI B73.1 dimensional standards for maximum interchangeability.
• Lower operating costs than standard centrifugal pumps at low-flow conditions.
• Balanced double-suction impeller design reduces axial thrust.
