Product Description

Industrial Integrally Geared API Pumps LMV341 High Speed Vertical Centrifugal Pump

Our API 610 OH6 series is a high-speed, integrally geared vertical centrifugal pump designed for precision performance in refinery and petrochemical environments. Engineered as a technical match for the LMV 341 series, this pump excels in high-head, low-flow applications where traditional multi-stage pumps are inefficient.

With a focus on operational reliability and compliance, our OH6 pumps ensure seamless integration into existing systems while providing advanced hydraulic coverage and robust gearbox technology.

Key Performance Advantages

API 610 OH6 Compliance

Fully compliant with the latest API 610 standards for integrally geared pumps, ensuring safety and reliability in hazardous industrial zones.

Optimized NPSH with Inducer Technology

Available inducers significantly lower the Net Positive Suction Head required (NPSHr), protecting the pump from cavitation during volatile fluid handling.

Compact Vertical Design

The vertical inline configuration saves valuable floor space and simplifies piping layouts compared to horizontal multi-stage alternatives.

Drop-in Replacement Capability

Designed with matching 3 x 2 inch dimensions and flange ratings, this series serves as a direct technical alternative to LMV 341 installations, minimizing downtime during upgrades.

Technical Questions and Answers

Is this pump a direct alternative for the Sundyne LMV 341?

Yes. Our OH6 series is engineered to match the hydraulic performance and mounting dimensions of the LMV 341, allowing for a streamlined transition without major piping modifications.

How does the pump handle cryogenic or high-temperature fluids?

By utilizing different build codes, such as Build O for temperatures down to -240 °F, we employ specialized materials like 15-5PH shafts and 316 SS cases to ensure structural integrity across a wide thermal range.

What sealing options are available for hazardous hydrocarbons?

We provide Single, Double, and Tandem seal configurations. These are paired with various API Flush Plans (such as Plan 52 or 53) to ensure secondary containment and seal cooling for dangerous fluids.

Can the pump performance be adjusted if process conditions change?

Yes. The modular design features replaceable diffuser inserts and impellers, allowing the pump to be re-rated for new flow or head requirements without replacing the entire unit.
