Services

The Goulds LF 3196 pumps are designed for a total range of industry services, including:

• Specialty chemicals
• Batch chemical process
• Reactor feed
• Shower service
• Boiler feed
• Condensate
• High pressure process
• Column reflux
• Column bottoms
• Hot oil
• Seal water

Mechanical / Hydraulic

Performance Features for Low Flow Services:

• Concentric (Circular) casing
• Radial vane impeller
• TaperBore™/Big Bore™ Seal Chambers
• Power Ends
• Optional centerline mounted casings

Extended Pump Life & Reliability:

• Concentric (circular volute) casing and open radial vane impeller designed to eliminate hydraulic and mechanical problems at throttled low flows.
• Radial loads reduced by as much as 85% compared to end suction expanding volute pumps at low flows.
• Rigid shaft designed for minimum deflection at seal faces (less than 0.002 in. / 0.05 mm).
• Bearings sized for 10-year average life under tough operating conditions.
• Premium Severe-Duty Thrust Bearings increase bearing fatigue life by 2-5X.
• Optimized Oil Sump Design: 10%-20% increased sump size for better heat transfer and cooler bearings; contoured design directs contaminants away from bearings to a magnetic drain plug.
• Inpro® VBXX-D Hybrid Bearing Isolators with stainless steel rotors for maximum protection against contaminants and corrosive effects.
• Continuous performance maintained by simple external impeller adjustment.

Ease of Maintenance:

• Back pull-out design.
• Parts interchangeable with Goulds 3196 (LF 3196 uses all Goulds Model 3196 parts except casing and impeller).
• External impeller adjustment.
• Easy retrofit for existing ANSI pumps not designed for low flow operation.

Safety:

• ANSI B15.1 coupling guard.
• Ductile iron frame adapter (material strength equal to carbon steel).
• Raised face flanges, serrated for positive sealing.
• Optional shaft guard.

Patented Intelligent Monitoring:

• Condition Monitor: Continuously measures vibration and temperature at the thrust bearing. Colored LEDs indicate general pump health, providing early warning of improper operation.

Sealing Flexibility: To meet ANSI B73.1M specifications, Goulds offers a wide range of sealing arrangements and seal chambers:

• Packed Box: Teflon*-Impregnated Fiber Packing, Standard Bore Stuffing Box.
• Single Inside Seal: Flexibly Mounted Seal with Throat Bushing, BigBore™ Seal Chamber (or TaperBore™ if throat bushing not required).
• Conventional Double Seal: BigBore™ Seal Chamber.
• Tandem Seal: TaperBore™ Seal Chamber (or BigBore™ if throat bushing required).
• Engineered seal chambers improve lubrication and heat removal for extended seal life.
• Fully confined gasket at casing joint protects alignment fit and eases disassembly.

High Temperature LF 3196 Features (for 500˚-700˚F / 260˚-370˚C services):

• Centerline-mounted casing
• Graphite casing gasket
• Graphite impeller O-ring
• Jacketed stuffing box
• High temperature bolting
• Stainless steel shaft
• Finned oil cooler

Dimensions and Weights: The bare pump dimensions (X, A, B, D, SP) and weights vary by pump size (e.g., 1x1½-4, 1x1½-8, 1x2-10, 1½x3-13).

• Shaft Diameters: Range from 0.75 in. (19 mm) at impeller to 2.5 in. (64 mm) between bearings.
• Seal Chamber Bores: BigBore™ Seal Chamber bore ranges from 2.875 in. (73 mm) to 3.875 in. (98 mm). Stuffing Box bore ranges from 2 in. (51 mm) to 2.875 in. (73 mm).
