Trillium Flow Technologies updated MESB pump range builds on the engineering excellence, innovation, and heritage of our Gabbioneta Pumps® and Termomeccanica Pompe brands. Our expertise in designing and manufacturing BB5 pumps dates back to the 1970s, with hundreds of units installed worldwide. This API-compliant BB5 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. The MESB has an inline impeller arrangement to minimise bearing span, and provide a more compact design. The pump range is available with bolted or shear ring end cover arrangements.
