Goulds Pumps 3600 - IOM - Manual (Page 16)

Product Description
• Constant-level oilers and labyrinth seals are standard.
• No machining is required to convert the standard ring oil lube to either purge-oil or pure-oil
mist (pure-oil mist applications require minor bearing housing modifications).
• Pressure lubrication is required with hydrodynamic thrust bearings.
Bearings
Bearing type Characteristics
Inboard (radial)
• Consists of a single-row deep-groove ball
bearing (standard)
• Carries only radial load
• Optional sleeve bearings (standard for size
6x8-13 pumps)
Outboard (thrust)
• Consists of a pair of single-row angular contact
ball bearings mounted back-to-back (standard)
• Shouldered and locked into place, enabling the
bearing to carry both radial and axial thrust
loads
• Optional hydrodynamic thrust bearing (used
with sleeve-type journal bearings)
Shaft
The heavy-duty shaft has the following characteristics:
• Designed for cartridge mechanical seals
• Minimal shaft deflection at the seal faces (0.002) when run in the worst-case condition
(typically minimum flow)
• Critical speed at least 20% above design operating speed
• Fully compliant with API 10th Edition (ISO 13709)
Baseplate
The fabricated steel baseplate supports the pump, driver, and accessories in accordance with
API-610 10th Edition (ISO 13709) requirements.
Direction of rotation
The shaft rotates counterclockwise when viewed from the power end.
Intended applications
Model 3600 is designed to meet the rigorous demands of the petroleum and petrochemical
industry.
Nameplate information
Important information for ordering
Every pump has a nameplate that provides information about the pump. The nameplate is
located on the pump casing.
When you order spare parts, identify this pump information:
• Model
• Size
• Serial number
• Item numbers of the required parts
Refer to the nameplate on the pump casing for most of the information. See Parts List for item
numbers.
