Choosing the wrong pump can delay your working process and result in an increased number of mistakes in the production unit. You should know everything about cast-iron barrel pumps for smooth and durable operations before you invest in cast-iron barrel pumps.

Cast Iron Barrel Pumps – What Are They?

A Cast Iron Barrel Pump is a manually operated or mechanically powered machine used to move liquids in the form of barrels, drums or containers. These pumps are made of heavy-duty cast iron, which is famous due to its strength and durability.

Compared to lightweight plastic or aluminium pumps, cast iron pumps are designed to work with viscous fluids, as well as challenging industrial conditions. One of the types – a cast iron rotary barrel pump – operates on the rotary system, which enables a smooth and constant transfer of fluids with minimum effort.

They are popular among Cast Iron Barrel Pump Manufacturers In India and other suppliers worldwide, as they are used in automotive, manufacturing, agricultural, and chemical processing industries.

Fun Fact- “"Self-Sealing" Property: When used in oil-based applications, cast iron pumps can develop a protective layer that actually helps prevent corrosion, unlike when they are exposed to water.”

Types of Cast Iron Barrel Pumps

The following are the types of cast iron barrel pumps:

1. Rotary Barrel Pumps

They ensure smooth and continuous operation with less effort as compared to lever pumps. They are suitable for oil, diesel and lubricants. 

2. Lever Action Barrel Pumps

They ensure better control and lower flow rate as compared to rotary pumps. They require less manual effort. 

3. Piston Barrel Pumps

They ensure accurate fluid delivery and are suitable for thicker liquid. They are used for viscous liquid like chemicals, heavy oils, and grease. 

4. Diaphragm Barrel Pumps

They can handle corrosive liquid because they are safe for chemical handling. They come with a leak-proof design. 

5. Electric Barrel Pumps

They require minimal manual effort and are suitable for continuous operations. They are used in large-scale industries and bulk liquid transfer.
