Structural advantages
Shaft seal: choose BURGMANN mechanical seal or packing seal. It can guarantee 8000 hours running without leakage.
Bearings: SKF and NSK bearings are selected to ensure smooth operation and low noise.
Installation form: no need to be adjusted during assembly, and can be used according to field conditions. Vertical or horizontal installation.

Material selection
Except for the high quality carbon steel of the shaft, most of the materials are made of cast iron.

Product features
The pump shell is horizontally opened, which is convenient for inspection and maintenance
No axial force, so it can keep stable operation
Low noise and long service life
Compact structure, easy to install.
Stable operation: double suction impeller design reduces axial force to a minimum.
Corrosion resistance: the pump body is forged by precision casting industry, and has significant corrosion resistance and high efficiency.
