Goulds VMP Autoprime Pump

Summary

This document extract is primarily a safety manual for ITT Goulds Pumps and does not contain typical product specifications such as flow rates, pressures, or dimensions for a specific pump model.

Product Identification

This safety manual applies to ITT Goulds Pumps equipment. Specific models mentioned in a caution include:

• NM3171
• NM3196
• 3198
• 3298
• V3298
• SP3298
• 4150
• 4550
• 3107

ATEX Considerations and Operating Limits

ATEX conformance applies when the pump unit is operated within its intended use. Equipment certified for use in an ATEX classified environment is identified by an ATEX tag. A typical tag includes:

• II: Group 2
• 2: Category 2
• G/D: Gas and Dust present
• T4: Temperature class (can be T1 to T6)

The following table outlines the ATEX temperature classes:

The code classification on the equipment must match the specified installation area.

General Safety Warnings and Precautions

• A pump is a pressure vessel with rotating parts that can be hazardous.
• Avoid operation with blocked suction and discharge to prevent superheating and explosion.
• The pump may handle hazardous and/or toxic fluids (e.g., high temperature, flammable, acidic, caustic, explosive). Identify contents and prevent exposure.
• Never apply heat to impellers or impeller retaining devices for removal, as trapped liquid can rapidly expand and explode.
• Always ensure the coupling guard is correctly installed before operation.
• Never run the pump below recommended minimum flow, dry, or without prime.
• Always lock out power to the driver before performing maintenance.
• Never operate the pump without safety devices installed.
• Never operate the pump with discharge or suction valves closed.
• Do not change service application without approval from an authorized ITT Goulds Pumps representative.
• Wear appropriate safety apparel: insulated work gloves, heavy work gloves, safety glasses with side shields, steel-toed shoes, and other personal protective equipment for hazardous/toxic fluids.
• Properly lift and support assembled pumping units and components at identified lifting points.
• Follow shaft alignment procedures and coupling manufacturer’s instructions.
• Do not force piping into place at flanged connections.
• Use proper fasteners, replace corroded ones, and ensure all are tightened.
• In potentially explosive environments, ensure the motor and coupling are properly certified and the coupling is made from non-sparking material. Dynamic seals are not allowed in ATEX classified environments.
• Avoid operating the pump in reverse rotation.
• Follow impeller clearance setting procedures to prevent sparks and heat generation.
• If using a cartridge mechanical seal, install centering clips and loosen set screws before setting impeller clearance.
• Properly lubricate bearings to prevent excess heat, sparks, or premature failure.
• Never operate the mechanical seal dry, even for a few seconds.
• Never attempt to replace packing until the driver is locked out and the coupling spacer is removed.
• Ensure the pump is isolated from the system and pressure is relieved before disassembly, removing plugs, opening valves, or disconnecting piping.
• Allow all system and pump components to cool before handling.
• For specific models (NM3171, NM3196, 3198, 3298, V3298, SP3298, 4150, 4550, or 3107) with plastic parts, be aware of static electric discharge risk if the pumped fluid is non-conductive.

Parts

The use of genuine Goulds parts is recommended for safest and most reliable operation.
