Multistage Ring Section Boiler Pump EDG/EDF (BB4)
EDG/EDF IS BB4 type horizontal multistage Boiler Pump, be used as high pressure pumps that is designed according to API610 10th. The impellers are stacked back to back symmetrically , therefore the axial hydraulic thrust is automatically balanced. Because of the balance drum being canceled, the maintenance cost is reduced and the working is more reliable. The rotors are perfectly dynamically balanced and the maximum stages can be up to 16stages. EDG/EDF type multistage ring section pump is the ideal high pressure pump for your high pressure application.
Features
3D design used in the whole design process and CFD analysis and being embodied with knowledge and experience of the fluid experts in EU-Flo
Back-to-back impeller stacking to automatically balance the axial hydraulic thrust.
Optional inducer stage with fine inducer impeller to allow very low NPSHr.
The suction nozzle and discharge nozzle can be horizontal, vertical, down, any position in times of 90 degree.
Optional shaft sealing for single mechanical seal, double mechanical seal, cartridge mechanical seal and soft packing meet API 682
Standard design for stuffing box cooling jacket allow the pump to transfer high temperature liquid.
Bearing bracket with cooling jacket or finned shape cooled by fan to ensure long bearing life and stable pump working.
Bearing lubrication is optional for grease, ring oiled, splashed systems or boosting systems.
Bearing type can be rolling element bearing and plain bearing. for heavy duty and high temperature
