NexGen Cryo™ Gen 4 pumps feature

  • Increased efficiency through improved hydraulics and variable speed operational control.
  • Compact design/ease of maintenance: High speed medium voltage motors for greater efficiency, fewer parts, and lower weight for easier maintenance.
  • Future proofing: Will require fewer models than previous generations & will be cost effective to manufacture.
  • Lower CAPEX will reduce CAPEX by packaging to reduce construction time and lower field labor cost.
  • Increased reliability & reduced OPEX: (MTBO-MTTR)/MTBO is significantly higher than competition due to the reduced MTTR.
  • Greener Footprint: Lower boil-off gas and lower power consumption, energy recovery and power regeneration.

High Efficiency

• Reduce power consumption
• Lower OPEX
• Industry leading payback period (~less than 3 years)

High Specific Speed Design

• Higher efficiency
• Smaller footprint & lighter construction
• Smaller column diameters (In-Tank pumps)

Thrust Balance System

• Longer bearing life > 25,000 hrs.
• Start-up cushioning of pump axial thrust

Standardized Machine Components

• Repeatability & consistency
• Higher efficiency
• Higher availability

High Speed Medium Voltage Motors

• Smaller footprint & lighter weight (1)
• High energy density
• Larger turn down ratio’s (5+) / increased flexibility
• Higher efficiency (2-10% more compared to traditional submerged motors) (3)

Variable Speed Drive

• Flexibility – Widest Operating ranges
• Soft start – reduce In Rush Current
• Increase Reliability

XTRinducerTM

• eXTReme lower end  NPSH performance
• Reduced tank height
• More saleable LNG (less dead stock)

Ceramic Ball Bearings

• Longer bearing life (2)
• Reduce MTBO
• Silicon Nitride = extremely hard balls for abrasion resistance
• Cryogenic clearances & testing = fit for use in cryogenic applications

Notes

  1. High speed medium voltage motors reduce the weight and size by 33% compared to Induction motors and are more efficient!
  2. Tungsten Disulphide coating for lubrication and reduced wear = longer bearing life
  3. This efficiency is also more stable at varying load conditions (vs relatively fixed-point efficiency for Induction Motors)
