Desing Details pump snw
Bearings / Lubrication
Pump shaft and the intermediate transmission shafts rotate on friction bearing bushes lubricated by the pumped liquid.
Drive and gear head shafts (in case of internal combustion engine) rotate on bearings lubricated with oil or grease, depending on coupling system size.
Design
Radially-split vertical multistage pump casing. Closed impeller with diffuser. Strainer in suction.
Manufactured in nominal diameters of 6”-8”- 10”-12”-14”-16”- 20”-22”.
Fields of Application
BEV are vertical multistage centrifugal pumps designed for deep well, ditches and tanks to pump clean liquids without any abrasives or solid particles.
BEV-LO are vertical multistage centrifugal pumps designed for main engine lubrication service.
Such deep well line shaft turbine pumps are often used for irrigation, mainly in areas where no electric power is available (thus the engine driven option) and the water table is at fairly low level.
Other typical applications would be:
· Water supply in urban and rural areas
· Fire fighting sets
· Industry
· Water raising for reservoirs and channels
Coupling
Flexible coupling with electrical motor and cardan joints in case of internal combustion engine.
Coupling Guard: Transparent plastic protections are supplied as standard. Metallic protections can be supplied as option.
