Product catalog summary
Introduction
The Aurora 326A Series is a commercial in-line mounted centrifugal pump designed for high-temperature condensate service and boiler feed applications. It offers capacities up to 140 G.P.M. and heads up to 55 feet, with a maximum operating temperature of 225°F. The pump is engineered for space-saving, maintenance-free operation with universal flange-to-flange dimensions for easy installation.
Design Features
The pump features a quieter operation due to an inlet straightening vane and a low vibration motor. It is hydrostatically tested to 1.5 times the maximum operating pressure and supports quick installation due to its compact design. The vacuum cast bronze impeller ensures maximum efficiency and durability, while the pump's design reduces the need for spare parts.
Maintenance and Reliability
The 326A pump is maintenance-free with enlarged motor bearings and a standard seal flush line for proper lubrication. It features a stainless steel oversized pump shaft to minimize deflection and increase seal life. The integral pump/motor shaft design eliminates failures due to couplings or shaft extensions.
Performance Data
The pump is available in standard and build-to-order models, with a range of features including a stainless steel shaft, vacuum cast impeller, and high-temperature mechanical seal. It includes tapped suction and discharge gauge ports for performance testing and three casing vent plugs for easy access.
Engineering Specifications
The pump can be specified in bronze fitted, all iron, or all bronze constructions. It is capable of horizontal or vertical mounting and is close-coupled to a NEMA motor. The motor is designed to meet specific vibration limits.
Material of Construction
The pump casing, impeller, and motor bracket are available in cast iron or bronze, with a stainless steel shaft and ceramic mechanical seal. The maximum operating pressure is 175 psi, and the maximum temperature is 225°F.
