Fiberglass Integrated Prefabricated Pump Station

A FRP integrated prefabricated pump station is a complete set of equipment designed, manufactured, and assembled in a factory. Its cylinder is constructed of fiberglass reinforced plastic (GRP) and integrates pumps, piping, valves, control systems, gratings, and a maintenance platform. The pump station is then transported to the site for installation.

Its core operating principle is automatic collection and lifting.

1. Sewage Collection: Sewage/rainwater from the municipal pipeline network, buildings, or factories flows through inlet pipes into the FRP cylinder of the pump station.

2. Liquid Level Control: Liquid level sensors (such as floats or pressure sensors) within the cylinder monitor the water level in real time.

3. Automatic Pump Start: When the water level reaches a set start level, the control system automatically starts one or more submersible pumps.

4. Pressurized Conveying: The pump lifts sewage through a pressurized pipe and outlet valve to a higher elevation or a more distant municipal pipe network.

5. Automatic Stop: When the water level drops to the set stop level, the pump automatically stops.

6. Circulating Backup: The system typically features multiple pumps, which operate in rotation or simultaneously, providing backup and ensuring reliability.

Why is FRP commonly used for pump station cylinders?

This is because FRP's material properties perfectly match the application requirements of the pump station:

1. Excellent Corrosion Resistance: Sewage, rainwater, and the various chemical components they contain (such as hydrogen sulfide and acidic substances) are highly corrosive to concrete and metal. FRP is inherently immune to these corrosion effects, resulting in an extremely long service life.

2. Leakage-Proof, Environmentally Friendly: The FRP cylinder is seamlessly wound and seamless, fundamentally eliminating leakage. Concrete pump stations, on the other hand, are prone to cracks, which can cause sewage to seep into the ground, contaminating the soil and groundwater.

3. High Strength and Lightweight.

Fiberglass boasts high strength and can withstand soil pressure and dynamic ground loads. At the same time, it weighs only one-quarter of concrete.

4. It is extremely easy to transport and hoist, significantly reducing installation costs and complexity.

5. Smooth Interior and Excellent Self-Cleaning Properties

The interior of the fiberglass is extremely smooth, with an extremely low roughness coefficient (n<0.01), resulting in low flow resistance and a low tendency to scale buildup, effectively preventing dirt accumulation and blockage.

6. Flexible Design and High Customizability

The cylinder diameter, height, and internal configuration can be flexibly customized based on the project's required flow rate, head, and site conditions.

A complete prefabricated fiberglass integrated pump station includes:

1. Fiberglass Cylinder: The core container, providing structural strength and corrosion protection.

2. Submersible Sewage Pump: The core power source, typically one to three units, installed in the pump pit or with a built-in rail system for easy maintenance.

3. Lifting Rail System: The pumps can be easily lifted to the surface along the rails for maintenance, eliminating the need for personnel to descend the pit. 4. Pressure Piping System: Includes outlet pipes, check valves, gate valves, etc., typically made of stainless steel.

5. Intelligent Control System:

Control Cabinet: Typically installed outdoors or on the ground, it contains a PLC for fully automatic operation, remote monitoring, and fault alarms.

Level Sensor: Precisely controls the start and stop of the pump.

6. Pulverizing Screen/Basket Screen: Used to intercept and crush solid debris (such as fibers and plastics) to prevent pump clogging.

7. Ventilation System: Exhausts harmful gases from the cylinder.

8. Bottom Self-Cleaning Design: Many products feature an anti-siltation design (such as a concave bottom) that uses the pump's impact force to automatically agitate sediment and prevent sludge compaction.

Comparison with Traditional Concrete Pump Stations

Summary

The FRP integrated prefabricated pump station represents the technological advancement in drainage. Leveraging the superior performance of FRP materials and the integrated, intelligent design of factory prefabrication, it seamlessly addresses the challenges of traditional pump stations, including corrosion, leakage, slow construction, difficult maintenance, and large footprint. It's more than just a product; it's a plug-and-play, efficient, and reliable drainage solution, providing strong support for modern urban development and environmental protection.
