General Description
The pumps are horizontal multistage centrifugal pumps of ring-section design, which meet the technical requirements of ISO 5199 / EN 25199.
The advanced modular design reduces the number of parts whilst maximising interchangeability.
Optimal selection of impeller diameter and diffuser size for each ensures that the pump closely match the required duty conditions.
The pump eliminates traditional balancing disc components and adopts a patented mechanical sealing unit to balance the remaining axial force, which can meet the requirements of variable frequency and
requent start-up. (This structure is only suitable for mechanical seals)
When configuring gland packing seal, use a balance disc to balance the remaining axial force. Materials Specifications for Pump Main Parts
