Sulzer's pumps that comply with API 610 OH3 standards mainly come in two series: OHV series and OHVL series. Among them, OHV is the standard main product of this type, covering the widest range of performance; OHVL is a supplementary series specifically designed to fill low flow and high head operating conditions.

The following is a detailed introduction to the structural characteristics, parameters, and application industries of these two series.

🔧  structural characteristics
Both series are based on the API 610 OH3 type (vertical cantilever pipeline pump) design, with a compact structure but slightly different emphasis.

OHV series (standard type)

Core design: vertical, cantilever, centerline support. Adopting a rear pull structure, there is no need to disassemble pipelines and motors during maintenance, which is very convenient.

Long life design: equipped with a bearing box with fins and a cooling fan, effectively dissipating heat and extending bearing life. Adopting sturdy OHH type pump shaft and bearings to minimize shaft deflection and extend sealing life.

High stability: Using heavy-duty pumps and motor brackets significantly reduces operational vibration. The pump casing is designed for twice the API 610 standard pipe opening load, with high structural strength.

Sealing and lubrication: Equipped with ISO 21049 (API 682) containerized mechanical seals to reduce leakage. Optional grease lubrication or pure oil mist lubrication methods.

OHVL series (low flow type)

Hydraulic optimization: Adopting a unique low flow impeller and guide vane design, stable and smooth head flow curves can be obtained in low flow areas.

High compatibility: A large number of components commonly used with the OHV series, such as bearing brackets and mechanical seals, are adopted, effectively reducing spare parts inventory and lowering operation and maintenance costs.

📊  Core parameters
The two series together cover a wide range of performance, and the following is a detailed parameter comparison:

Parameters OHV series (standard type) OHVL series (low flow type)
Flow rate can reach 1450 m ³/h (50Hz) 1-60 m ³/h
Lift can reach 350 m (50Hz) 20-450 m
Pressure can reach up to 51 bar
Temperature -160 ° C to+340 ° C -85 ° C to+340 ° C
Export size 25 to 250 mm 25 to 50 mm
🏭  Application Industry
With the characteristics of space saving and stable and reliable operation due to their vertical structure, these two series are widely used in the following fields:

Upstream oil and gas and offshore platforms: very suitable for space constrained offshore platforms. Mainly used for key services such as seawater booster pumps, light hydrocarbon booster pumps, water injection, and auxiliary processes.

Refining and Petrochemicals: Used for various process flows in refineries, such as pump circulation services, vacuum wax oil (LVGO/HVGO) transportation, low-pressure feeding devices, etc.

Land terminal and storage: In oil depots and transfer stations, it is commonly used as a tank area booster pump to transport finished oil or other liquids.
