Product catalog summary

Overview: The AURORA® 3310 Series features horizontal and vertical close-coupled pumps designed to save space and reduce installation costs. Models 3311, 3312, and 3314 offer capacities up to 3800 GPM and heads up to 450 feet, suitable for temperatures up to 275°F.

Specifications:

Capacities: 70 to 3,800 GPM (16 – 863 m3/hr)
Heads: 40 to 240 feet (12 – 137 m)
Temperature: Up to 275°F (135°C)
Pressure: 300 psi case working pressure

Standard Features:

Horizontal and vertical close-coupled configurations
Load-bearing suction and discharge flanges
Cast iron, bronze fitted construction
Double volute on 6” discharge and larger
Heavy-duty power frame with regreaseable bearings
Precision cast, dynamically balanced impeller
Hydrostatic test at factory for casting and seal integrity
Bronze shaft sleeve and mechanical seal with carbon against ceramic face

Optional Features:

Coupling guard
Formed steel bases
316 stainless steel sleeve and shaft
High-temperature mechanical seals
Abrasive separators

Performance Data: Performance data is provided for various RPMs (3000/3600, 1500/1800, 1000/1200), with a recommendation to check individual performance curves for final selection.

Dimensional Data: Detailed dimensional data is available for different pump sizes and configurations, including small, large, and extra-large power frames.

Engineering Specifications: Requirements for flexible close-coupled pumps include specific materials and construction details for installation.

Specifications: The pump must have a bronze or stainless steel shaft sleeve extending the length of the seal plate, with a gasket-sealed shaft extension to prevent contact with pumped liquid. Impellers should be cast bronze, dynamically balanced, and key locked to the shaft.

Flexible Coupled-Frame Mounted (3314): Pumps and motors are mounted on a common steel or steel fabricated drip rim baseplate. The shaft, made of steel or stainless steel, is installed in a cast iron power frame. The design allows for a maximum shaft deflection of .002” at the seal face under maximum load. Grease ball bearings have a minimum life of 3 years under maximum load conditions. The pump is flexible coupled to a standard horizontal NEMA motor, with alignment checked per Hydraulic Institute standards to ensure no strain is transmitted to the pumps.

Horizontal Close-Coupled (3311): Each pump is close-coupled to a HI-NEMA motor, with all models having motors supplied with feet.

Vertical Close-Coupled (3312): Each pump is close-coupled to a HI-NEMA motor.
