Alternative to Sundyne LMV 322 Vertical High Speed Centrifugal Pump
LMV322 High-Speed Vertical Centrifugal Pump - The Perfect Solution for High-Speed Liquid Transfer
For industrial users seeking a high-performance alternative to the Sundyne LMV 322, stability and compatibility are the core requirements. Leveraging 18 years of dedicated R&D in high-speed centrifugal pumps, Sunstrand has successfully launched the LMV 322 replacement model - fully compliant with API 610 (OH6).
We have achieved not only a true "drop-in" physical replacement, but also - based on global delivery experience from 20,000 units - made targeted improvements to mechanical seal life under extreme pressure pulsation conditions.
The Sunstrand LMV 322 features identical flange center-line distances, baseplate bolt hole patterns, and auxiliary piping connections to the original model. This means that during maintenance or upgrade, you can achieve a seamless transition without any modification to existing process piping.
Our hydraulic engineers have used modern CFD to perfectly replicate and optimize the original hydraulic performance curve.

Not only is the complete pump interchangeable - Sunstrand-manufactured high-speed shafts, impellers, inducers, and mechanical seals can be used directly in your existing Sundyne LMV 322 pump sets, providing a cost-effective alternative sourcing option.
- Fine Chemicals: For high-pressure MDI/TDI circulation, our optimized API 682 seal configuration more effectively prevents seal wear caused by crystallization.
- Oil Refining: For hydroprocessing units, Sunstrand supplies material grades (e.g., Duplex SS, Hastelloy) with 3.1 material traceability reports to ensure compliance.
- Liquid Transfer (Energy): Our improved high-efficiency inducer provides better cavitation resistance than standard replacement parts when handling low NPSHa conditions.
