RCBB5
The RCBB5 double casing, radially split, between bearing pumps (barrel pumps) are designed to meet high pressure and temperature requirements in the oil and gas and power generation industry. The RCBB5 pumps are designed to meet the toughest and most demanding requirements of API 610. The barrel can be fi tted with single- or multistage inner case assemblies, using volute or diffuser casings. The axial thrust loads are balanced by opposed impeller design or axial balancing drums. The barrels are made of forged or cast materials to meet the required strength. The RCBB5 pumps offer seal chamber design in accordance with API 610 to allow installation of API 681 single and double cartridge types of mechanical seals.
