HPT300-340-03-05 balance drum is a core component designed for multi-stage high-pressure boiler feed water pumps. It is used to balance axial force, reduce rotor displacement, and ensure long-term stable operation of the pump unit under high temperature and high pressure conditions. This product adopts advanced structural design and material technology, and is widely used in industrial fields such as electricity, chemical industry, and metallurgy, significantly improving pump efficiency and equipment life.

 

​High-efficiency balancing ability: reduce bearing load and extend service life.

​Resistant to extreme conditions: supports working temperature range of -30℃~250℃, maximum pressure of 15MPa, and adapts to saturated water and high-temperature steam environments.

​Low maintenance design: non-contact dynamic balancing structure to reduce wear.

 

Model: HPT300-340-03-05

Applicable pump stages: 5-10 multistage centrifugal pumps

Outer diameter of balance drum: 300 mm

Working pressure: ≤15 MPa

Medium temperature: -30℃ ~ +250℃

Applicable media: high temperature water, boiler feed water, industrial fluid

 

Power industry: coal-fired/gas-fired power plant boiler feed water system, nuclear power auxiliary feed water pump.

Petrochemical: ethylene unit high temperature feed water pump, refinery high pressure circulation pump.

Industrial boiler: high pressure steam supply system for papermaking, metallurgy, and pharmaceutical industries.

 

High reliability: long trouble-free operation time under harsh working conditions, reducing the risk of unplanned downtime.

Energy saving and efficiency improvement: reduce energy loss caused by axial force, and increase pump group efficiency by 5%-8%.

Quick adaptation: modular design, support upgrading and transformation of existing pump groups, and easy installation.
