Glass-reinforced plastic (GRP) precast pump stations have gained widespread application in our country. GRP pump stations offer advantages such as corrosion resistance, lightweight, high strength, and long service life.

With the rapid economic development in our country, the demand for water resources has also increased significantly. Traditional concrete pumping stations, however, are prone to corrosion and damage due to their structural limitations; at the same time, the medium for concrete transportation is mostly water, which is susceptible to contamination or damage during transportation and construction. Additionally, laying concrete transportation pipelines requires a large area and space. Therefore, in recent years, the government has strongly promoted the use of new fiberglass pipelines to replace traditional concrete pipelines for urban water supply system construction.

Fiberglass Reinforced Plastic (FRP) is a general term for a type of composite material, consisting of a composite product made from materials such as resins (unsaturated polyester) and glass fibers. Currently, the widely used composite products on the market are those made with an epoxy matrix and reinforced with glass fibers - FRP molding products (abbreviated as FRP).
