Small Capacity (Model 3408A): Handles flows up to 8,000 GPM, heads up to 570 feet, and temperatures up to 250°F. Features grease-lubricated bearings and mechanical seals for general-purpose applications.
Medium Capacity (Models 3409, 3410): Supports flows up to 12,000 GPM and heads up to 850 feet, with options for horizontal or vertical mounting and various bearing lubrication methods.
Large Capacity (Model 3420): Accommodates flows up to 65,000 GPM and heads up to 400 feet, offering sleeve bearings and vertical mounting options.
Extra Large Capacity (Model 3498): Designed for flows up to 225,000 GPM and heads up to 800 feet, featuring double row thrust bearings and renewable impeller wear rings.

Design Features:

Large Inlet Areas: Reduce NPSH requirements and ensure smooth flow to the impeller.
Stuffing Box: Standard packing with options for various mechanical seals.
Positive Liquid Sealing: Enhances reliability by sealing the shaft from pumpage.
Renewable Wear Rings: Facilitate easy maintenance and efficiency for both impeller and casing.
Heavy Duty Shafts and Casings: Withstand high pressures and minimize deflection for long service life.
Balanced Design: Dual volute casing and double suction impeller minimize axial thrust and enhance reliability.

Materials of Construction: Options include bronze fitted, all iron, 316 stainless steel fitted, and all 316 stainless steel, catering to different application needs and environments.

Applications: The Goulds 3400 series serves industries such as power generation, municipal water systems, and industrial processes, with models tailored for specific capacity and pressure requirements.

Specifications: Detailed specifications include dimensions, weight, and material construction for various pump models. Models like 20x24-28/G/H and 30x42-72* are listed with specific measurements and weights. Sleeve bearings, grease or ring oil lubricated bearings, and different types of seals are noted.

Procedures and Standards: Standard rotation is right hand (CW), with optional left hand (CCW) rotation. Steel casings have 150#RF flanges, and dimensions are not for construction or installation purposes. Bottom suction and vertical mounting are available for some sizes.

Materials of Construction: Materials include cast iron, bronze, and 316 SS for casings and impellers, with details on packing materials and mechanical seal glands.

Recommendations and Best Practices: ProSmart™ is a wireless machinery monitoring system that enhances predictive maintenance, providing continuous monitoring and alerts to extend equipment life and reduce downtime.

PRO Services®: Services include product repair, reliability improvement, and asset optimization, emphasizing predictive analysis, condition monitoring, and root cause failure analysis.

PUMPSMART System Options: The PUMPSMART system offers energy savings, pump protection, and control schemes to maximize variable speed drive systems, allowing for future operating conditions with the same pump and minimizing inventory for critical services.
