SNMB pumps are designed for oil pumping and oil products for main and intra -commercial pipelines.
Design
SNMB Pumps Centrifice Horizontal multi-stage sectional sectional sectional one- or two-corps with a system of unloading the rotor from axial force using an unloading drum and a stubborn bearing. The pipes are located horizontally and directed from the pump axis in different directions.
Rotor supports are sliding bearings from forced or crankcase lubricant (or roller bearing with consistent or crankcase grease). The end seals - mechanical end, are made in accordance with the requirements of the API 682 standard.
Twisting torque from the engine to The pump is carried out using an elastic plate coupling.
