A tank is a construction or a container, usually for holding liquids, sometimes for gases. PVC tanks can be of many shapes, but large tanks tend to be cylindrical or to have rounded corners, to easier withstand hydraulic pressure of contained liquid. Features of a hard PVC tank are excellent corrosion resistance and lightweight and good sanitation to satisfy the requirements for a variety of applications. These tanks can be combined with metering pumps and agitators to further expand possible applications. Capacities range from 50 to 1000 liters to allow selection to fit the required application. Features of PVC tanks are excellent chemical resistance, impact resistance and ability to be used in poor environments.
