Why Choose Sundyne BB2?
Opt for the BB2 when your process requires maximum reliability under high temperature and pressure. Meeting API 610 11th Edition (ISO 13709) standards, it features a radially split, centerline-mounted casing with hydraulic balancing. Designed for continuous, heavy-duty operation, it supports both 50 Hz and 60 Hz drives and comes with advanced cooling and bearing protection systems—reducing life-cycle costs and extending service intervals
Main Features
Radial (horizontal) split casing, allowing rotor removal without disturbing piping or driver
Double-suction impeller with one- or two-stage options for balanced pressure and reduced NPSHr
Centerline-mounted, double volute design minimizes thermal distortion and radial load
Finned bearing housing dissipates heat, complemented by labyrinth seals to block contamination and preserve lubrication life
Sundyne Pumps and Compressors
API 682 mechanical seal chamber compatible with cartridge seal kits
Multiple impellers per casing available to tune for optimal efficiency across a broad operating range
Instrumentation-ready (temperature, pressure, vibration) with flange orientation options and welded drains/vents standard
Applications
Widely deployed in critical services such as:
Hydrocracking, gas condensate, HDS, platforming and topping duties
Crude & gas pipeline boosting
Solar thermal, charge pumping, and low-shear process lines
Choose BB2 for its blend of API standard design, thermal stability, and operational flexibility. With double-suction hydraulics, a horizontal split casing, and heavy-duty internals, it delivers robust, low-NPSHr performance.
