LMV 311 High Speed Centrifugal Pump
The LMV311 High-Speed Vertical Centrifugal Pump represents the ultimate solution for high-speed liquid transfer demands in the global petrochemical and chemical industries.
As an experienced supplier in high-speed rotating equipment, Sunstrand provides a high-performance alternative to the LMV 311 that offers 100% dimensional interchangeability while incorporating localized improvements in durability and maintenance convenience.
- High-pressure ammonia reflux - Optimized seal chamber thermal balance design addresses original model's tendency for seal face freezing
- Proven reliability - Replacement solution has operated for more than 8,000 hours without maintenance in multiple million-ton-per-year refining projects
AGMA Class 12 precision with 17CrNiMo6 case-carburized and hardened steel construction
Rotor assemblies meet ISO 1940 G1.0 standards, ensuring quiet operation even at 15,000 RPM
CFD-simulated inducer design reduces NPSHr to below 2.0 meters, eliminating cavitation problems
Strictly follows API 610 (OH6) standards. Install directly on existing piping without modifications to flange positions, foundation, or motor wiring.
High-strength alloy steel forged gears precision ground to AGMA Class 12, maintaining low vibration amplitudes above 10,000 RPM.
- Standard compliance - Factory-tested to latest API 610 (OH6 layout) with full pressure and flow hydraulic performance testing
- Interchangeability guarantee - All core components (impeller, high-speed shaft, seals, casing) are 100% physically interchangeable with original LMV 311 pumps

Absolutely. Sunstrand's core components (impeller, shaft, seals, gears) are precision-manufactured to original equipment specifications, ensuring identical dimensional tolerances. Many customers are currently using Sunstrand spares to maintain their existing international-brand pump sets - a proven testament to our accuracy and reliability.
For challenging suction pressure conditions, we offer a high-performance inducer option. This is based on hydraulic models refined from our database of 20,000 delivered units, reducing NPSHr by more than 50% and significantly improving cavitation resistance under extreme conditions.
Safety is Sunstrand's bottom line. Every LMV 311 undergoes a hydrostatic test at 1.5 times design pressure and full-power performance testing. We provide complete Material Test Reports (MTRs) and dynamic balance reports for each unit, ensuring compliance with - and often exceeding - petrochemical industry safety standards.
