Horizontal, centrifugal, single-casing, multi-stage pump of sectional type, with a radially split casing, double-sided (opposite) arrangement of impellers (perception of residual axial force by means of a spherical double-row roller bearing)
Ability to apply technology TORO
- Pump type Centrifugal
- Installation method Horizontal
- Flow 45 – 1500 m³/h
- Pressure range 500 - 2000 m
- Efficiency up to 84%
- API-610 classification BB4
Pumps of the TSNS series are designed to create high liquid pressure in the main and auxiliary pipelines
- Modern energy-efficient flow path «Toro» providing full efficiency up to 84% (NKMZ patented technology)
- The pump impellers contain replaceable shroud wear rings made of a special alloy with a “ferum-free” base with an extremely low rate of corrosive and erosive wear for sea water
- The system of axial fixation of the impellers on the shaft makes it possible to locally unload the axial force, which makes it possible to avoid the use of loaded threaded elements in the flow part of the pump
- Inner body with multi-channel guide vanes minimizes hydraulic radial forces in any condition, down to minimum feed
- The use of labyrinth seals of bearing units allows maintaining the purity of lubricants at a very high level, thereby multiplying their overhaul cycle of maintenance
- Use of high torque nuts to allow assembly/disassembly of the pump without the use of expensive high torque hydraulic tools
