MKV500 pumps are designed to supply oil with a temperature of 313-343K (40-70 ° C) into the lubrication system of turbine units. Pumps MKV500-35, MKV500-35A, MKV500-35V, MKV500-35g are rotated by alternating current electric motors and are intended for continuous operation, and pumps MKV500-35B and MKV500-35D are used and used to work in emergency mode. < /p>
design
Pumps MKV500:
- centrifugal,
- Vertical,
- single -stage.
The upper support of the pump rotor is a supporting rolling bearing, and the lower is a sliding bearing lubricated by the pumped liquid. The direction of rotation of the pump rotor is clockwise if you look from the drive side.
