Normally Expansion Tank is made by semi-transparent materials, such as plastic. The reason why use this kind material is that we can easily observed the liquid level directly through the box instead of opening the cap.
The operating principle of expansion tank is that, when people run cars, the temperature of the coolant circulating through the water jackets naturally increases which will increase pressure in the cooling system. When the pressure builds to a high enough point, the radiator cap allows that pressure to escape into the coolant reservoir through a small hose, called an overflow hose connected by the neck of the radiator to the expansion tank. Most of the coolant that is forced into the expansion tank returns to the radiator naturally after a few hours or when the engine is cold.
Without expansion tank, cooling systems would explode under pressure or the coolant would be forced from the overflow tube on the radiator and leak onto the road. It is advisable to check expansion tank regularly.
We can provide all kinds of expansion tank and Brake Fluid Tanks with high quality and reasonable price. As we all know, expansion tank is a vital component in our car`s cooling system.

VP stainless steel plastic pump is made of macromolecute plastic, and the motor casing is made of stainles steel, which makes it nice and lightweight, The pump cna be widely used in family, enterpriseanf farms.
Cyllder water colled design ensures the possibility of long time fround use of the pumps, preventing being overheated and motor' long time operation, it has advanages of longer service life and easy maintenance. The float switvch can automatically cut off the powerr when it is overheated or when it over currence. This guarantee the security and reliability if operation even in the environment
Consition of usage:
1. The depth for the electrical pump below the water is more than 3mm
2. The temperature of the water is not more than 40 degree
3. The pH ius 5-9

As engine coolant heats up, it expands. The Coolant Expansion Tank provides additional storage for the expanding coolant and is commonly the location where coolant is added to the engine.
