Flow range: ~1200m3/h
Lift range: ~2800m
Design pressure: 11MPa
Application temperature: -20~125ºC
Application field: This series of pump is mainly used in industries of oil refinery, petrochemical engineering, coal chemical industry, power plant, environmental protection engineering, wastewater treatment, cement plant etc.
Suitable for transporting all kinds of neutral or corrosive medium such as clean, particle free chemical medium, oil, wastewater.
Our API 610 type BB4 pumps are multistage, centre line mounted, radial split, single or double suction, between bearing pumps. The pump and motor are flexibly coupled and installed on a common baseplate. The pump design is available in two executions, inline with balance piston or in back to back (opposed) impeller design. Due to the ring section casing design, the piping must be dismantled for removal of the rotor assembly.
1.Meet partly API 610 requirements
2.Top-top nozzle design
3.Double volute design
4.Single entry or Double entry impeller for low NPSHR characteristics
5.Rotor axially balanced with balance piston or back to back design of impellers
6.Seal area meet API 682
7.Mechanical seals and seal systems as per API682
8.Hydrodynamic or antifriction bearings
