1. Products: Naipu® NP-M series centrifugal slurry pumps and spare parts could fully interchange with world famous brand. These pumps are of heavy-duty construction, designed for continuous pumping of highly abrasive and corrosive slurries. They feature a wide choice of replaceable abrasion resistant metal casting liners and Impellers, which are all interchangeable within a common casting assembly.
A H, M, H slurry pumps are suitable for pumping slurry with hard particles and in high density in industrial sectors as of metallurgy, mining, coal, power generation and building material. These pumps can also be applied multi-staged in series.
These pumps are those of cantilever, horizontal and centrifugal ones, whose shafts can be sealed by packing seals or by centrifugal type seals. The positions of the pump outlet can be positioned at an interval of 45° According to different requirements, so eight different angles can be applied by rotation in installation.
2. Structural Image: M-series are suitable for severe slurry conditions with coarse particles and high competency:
2.1 Two types of material for wet parts (volute liners, front and back liners, impellers):
L high-chrome alloy
L highly wear-resistant rubber
2.2 Structure of shaft seals:
L Packing gland seals
L Pressure-reducing metal/ rubber gland seals
L Mechanical seals
The M. A H type slurry pumps have pump bodies (volute liners, front and back liners) that consist of replaceable wear-resistant metal liners or wear-resistant rubber liners, and impellers can also apply wear-resistant metal material or wear-resistant rubber material. The HH type slurry pumps only apply wear-resistant metal material as their pump bodies and impellers.
2. Structural Image:
L-Series slurry pumps are suitable for severe slurry conditions with coarse particles and high competency.
2.1 There are two types of material for wet parts (volute liners, front and back liners, impellers):
L Made of high-chrome alloy material;
L Made of highly wear-resistant rubber material researched and developed by Naipu company.
Both of them can fulfill the task of slurry pumping with high efficiency and long service life.
2.2 Structure of shaft seals:
L Packing gland seals;
L Pressure-reducing metal gland seals;
L Pressure-reducing rubber gland seals;
L Mechanical seals.
