Oil and petroleum chemicals: process pumping according to API 610
Centrifugal Pump · 2026-03-04
API 610 (equivalent to ISO 13709) is the centrifugal separation pump standard for oil, petrochemicals and gas. Compared to conventional industrial pumps, API 610 pumps are designed for high reliability, long continuous operation with flammable materials, high temperature and pressure.
How to classify.
- and treo:OH1 sets foot, OH2 sets center line (most common in refineries), OH3 to OH6 stands.
- BB (between the two axes):BB1 double-axis dividing shell, BB2 double-axis dividing shell, BB3 multi-layer dividing shell, BB4 multi-layer one-layer shell, BB5 multi-layer two-layer shell (barrel type) for very high pressure.
- Standing up and hanging:Pump the hole, or pump in the container (can) when NPSH is insufficient.
Some specific requests.
The pump body has a minimum pressure of approximately 40 bars at 38 °C, hydraulic test 1.5 times the maximum permissible working pressure, vibration limit (approximately 3 mm/s at BEP according to the references), pump wing balance according to ISO 1940 and mechanical decay according to API 682.
About the design age.
Previous versions require a minimum design life of 20 years and three years of uninterrupted operation; version 12 no longer specifies this number but requires the manufacturer to specify parts with a limited life.
Choose the right level.
Not all applications require API 610.With environmentally safe, low pressure, ISO 5199 pumps have lower costs.API pumps such as the KPP line are for high-standard cases.
