Product Description

1.Product Overview 
GDL vertical multistage inline pump is the latest model with the features of energy-saving and less space demand, easy to install and has stable performances. 
With AISI 304 stainless steel shell and wear resistant axle seal, the pump can live long service life without leakage. 
With hydraulic equilibrium to balance the axial force, the pump can run more smoothly with less noise, and it can be easily installed in the same level pipelines, which enjoys better installation conditions than model GDL. 
With these features, GDL pump can easily meet the needs and requirements for water supply and drainage for high buildings, deep wells and fire-fighting equipments.
