Description

The BB3 is a horizontal, axially split, double volute, opposed impeller, multistage pump, which is in full compliance with API610, 10th edition (ISO 13709). It is available in a range of hydraulic sizes and number of stages with material combinations to suit many applications. The pump may be supplied with either a single suction first stage impeller or supplied with double suction first stage impeller.
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. The internal inspection and overhaul only need to do every 4 years.

Applications

Widely used in medium and long distance pipeline transportation, process boosting, offshore platform water injection and crude oil transportation, seawater desalination, boiler feed water, Lean methanol and Semi lean methanol pump of coal chemical, deaerated water pump.
