API-610 type: BB4 – TMP model: MES – MES-D

About this product

Trillium Flow Technologies updated MES pump range builds on the engineering excellence, innovation, and heritage of our Termomeccanica Pompe brand. Our expertise in designing and manufacturing BB4 pumps dates back to the 1970s, with hundreds of units installed worldwide. This API-compliant BB4 pump range is a radially split, multi-stage, between-bearings, centerline-mounted pump with either a single or double suction first stage impeller for reduced NPSHr. These are often known as tie bolt, or segmental pumps. Key Features API 610 compliant Integral case connections to avoid non-destructive testing Heavy-duty shaft to minimize rotor defection and maximize uptime API 682 compliant seal chamber Single or Double suction Impeller Compact ring section design Bearing housing leverages common parts across all Trillium Flow Technologies between bearings pumps Balance line to ensure both seals remain at equal pressure Interstage take off options to support bespoke applications Tie bolt design to reduce cost and to accommodate thermal shock MAIN APPLICATIONS Boiler feed water for traditional power plants Water transmission pipelines & water distribution Condensate extraction High pressure auxiliary services in general industry, petrochemical & RO desalination plants OPTIONS All API material options: S-4,S-5,S-6,S-8,C-6,A-8,D-1,D-2, plus bespoke options High efficiency options for RO and power markets Composite wear parts, for improved efficiency and rotor dynamics Specialist Options: high speed over 6500 RPM, Interstage Take off Options
