The HP-BB5Z is a horizontal, heavy duty, radial split of inner pump casing, multistage, double casing centrifugal pump with both-end mounted, which comply with the requirements of API610 and ISO13709. It is normally centerline supported for thermal stability and maximum nozzle load capacity.
Benefiting from present high pressure pump structure, HP-BB5Z has been further improved by years of operational experience in the field. Reliable and mature structure makes the pump easier to maintain and has high operational reliability.

The HP-BB5Z has a particular self-balancing structure. Without the extra balance system like general multistage centrifugal pump, the HP-BB5Z is more safety and more reliable when pumping fluids with solid particles.
The whole pump core (core package) can be replaced within 8 hours. And all the maintenance and replacement parts can be done without removing inlet and outlet pipes and motor.
