Your expectation is our standard


The RPG RCBB3 series is designed as a multistage, heavy-duty, axial split casing pump in accordance with all of the requirements of API 610. It is engineered and built for high-pressure,
heavy-duty applications. The RCBB3 features a bigger shaft for low shaft deflection, and large sealing chambers to fit a wide range of API 682 single and double cartridge mechanical seals. Individual impellers balancing and complete rotor assembly balancing ensure optimal performance and minimal vibrations. The pump hydraulic design is fully optimized by using CFD (Computational Fluid Dynamics) analysis. Special designs are available to meet customer requirements.
