pumps like 20ndsn -M designed to ensure the unaccavaled operation of the main main pumps that pump oil according to main oil pipelines, and can also be used on oil refineries and oil deposits.
Design
Pump 20ndSN-M -centrifugal horizontal single-stage with a double-sided entrance, equipped with rolling bearings on a plastic lubricant.
The absorption and pressure pipes are made in flange, located in the lower part of the case and directed horizontally in opposite directions.
The end seals of the pump are mechanical, end type with organized leakage. For washing end seals, cyclone separators are used.
The transmission of the torque from the engine to the pump is carried out using an elastic plate coupling.
As an asynchronous explosion -proof engine with a capacity of 315 kW is used as the pump drive.
