Goulds VIDS

Summary

Product identification

Goulds Pumps Double Suction Vertical Pumps, Model VIDS, are designed for low-NPSH performance and extended service life. The VIDS line includes five unique models, each customized to project specifications:

• Model ZDS: Ideal for VS2 pumps in high-head mine dewatering and dirty sump applications.
• Model ADS: Perfect for VS2 pumps in medium-head mine water processing and dirty sump usage.
• Model BDS: Best choice for VS2 and VS7 pumps for energy and condensate applications.
• Model DDS: Select for VS2 pumps in raw water lift and VS7 pumps deployed in oil pipelines.
• Model FDS: Designed for VS7 pumps in oil pipeline and electric power station operations.

These pumps are available in open pit or can configurations.

Operating limits

• Double Suction impellers reduce Net Positive Suction Head (NPSH) requirements, an advantage that becomes important in larger pump sizes, particularly when pumping more than 3,500 gpm at 1,800 rpm.
• Single-stage VS-2 pumps can process liquids with concentrations of total suspended solids up to 10,000 ppm.
• A Double Suction Hydraulic Coverage Chart is provided in the official PDF, illustrating Capacity (GPM) versus Total Head (Ft/H₂O). See the official PDF for exact tabulated values.

Feed water

The pumps are designed to handle challenging feed water conditions, including:

• Dirty sump applications
• Mine water processing
• Raw water lift
• High concentrations of suspended solids
• Dirty liquids
• Contaminants
• High particle concentrations (e.g., for desalination)
• Raw water intake plagued by contaminants

Mechanical / hydraulic

The VIDS line offers specific models tailored to various hydraulic and application needs:

• Model ZDS: For VS2 pumps in high-head mine dewatering and dirty sump applications.
• Model ADS: For VS2 pumps in medium-head mine water processing and dirty sump usage.
• Model BDS: For VS2 and VS7 pumps in energy and condensate applications.
• Model DDS: For VS2 pumps in raw water lift and VS7 pumps in oil pipelines.
• Model FDS: For VS7 pumps in oil pipeline and electric power station operations.

Key features and advantages

• Low-NPSH Performance: Double Suction impellers reduce NPSH requirements, enabling shorter pump lengths, easier installation, and enhanced field operation.
• Solids Handling: Designed for pumping dirty liquids with high concentrations of suspended solids without bearing wear concerns. Bearings are protected by being completely isolated from high-pressure pumpage and contaminants inside enclosing tubes.
• Durability and Reliability:
  • Finite Element Analysis (FEA) of the pump structure and patented "O" Head design evaluates resonance frequency for reliable field operation.
  • Patented, rotor stabilizing, double volute design minimizes radial loads and prevents premature bearing failure.
  • Patented seal technology design facilitates maintenance, preventing premature seal failures from dirty applications.
  • Hydraulic, down-thrust loading ensures reliable operation with the rotor in tension, contributing to low vibration and extended bearing life.
  • An ingenious sealing arrangement isolates the oil lubricating the bearings and seal facings from dirty water in the pumpage using a bellow-type rotating mechanism.
  • Self-adjusting close-axial clearance between stationary and rotating faces provides a firmer seal, expanding as wear occurs.
• Fabrication and Maintenance:
  • Integrated pump casing design is easier to fabricate than typical two-piece construction, leading to shorter delivery times.
  • Patented seal technology design facilitates maintenance.

Applications

Goulds Pumps Double Suction Vertical Pumps are suitable for a wide range of industrial applications:

• Mining: Dewatering and water supply for all excavation types, acid leaching, and extractions from ore deposits.
• Oil and Gas: Crude oil distillation and recovery, oil pipeline transport, transfer loading and unloading (where low NPSH is critical), water and CO₂ injection for oil recovery.
• Power: Nuclear service, cooling water (main and intermediate circulation, blow-downs), condensate extraction with fluctuating loads, and heater drain for tight controls.
• Industrial: Steel mill cooling, quench process and water services, descaling calorifiers, boilers, cooling circuits and heating systems, fire protection for NFPA services, secondary effluent circulation in industrial processing, API process services for medium and high-pressure applications, and flood control water transport in storm conditions.
• Sea Water: Desalination of water with high particle concentrations, and sea water intake involving impingement and entrainment.
• Water: Raw water intake plagued by contaminants, and water supply and distribution.
