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.
