VERTICAL IN-LINE MULTISTAGE CENTRIFUGAL PUMP

摘要

The invention relates to the field of mechanics and specifically to a vertical in-line multistage centrifugal pump designed to operate under high-load and low-flow conditions. Owing to its design, the pump is easy to maintain and inspect, does not require oil and/or grease for lubrication, does not require high-axial-thrust and radial bearings, does not require journal bearings and does not require hydraulic balancing drums.
