Profile: RMSpumptools specializes in artificial lifts. We have BS EN ISO 9001 quality certification. Our extensive range of products includes completion systems, mechanical products and electrical products. Our services range from concept & design, production through to installation and training. Our dual concentric/multiple zone system is a kind of completion system. It comprises of dual ESP system. These ESP system produces two production zones in the same well without co-mingling the fluids. The upper zone is produced by the upper ESP which is configured with our dual flow Y-Tool. The lower ESP, which is encapsulated in the pressure-tight shroud pumps the lower zone. The tailpipe of the shroud is fitted with a seal mandrel that engages into the PBR of a permanent packer, separating the two production zones. Co-mingling of fluid is prevented by the use of a separate concentric tubing string inside the main production string, creating a micro annulus. The concentric tubing is fitted with a seal mandrel that locates in the seal bore in the dual flow Y-Tool.
