Different Types of Drum Pumps And How They Work

What is a Drum Pump?

Liquids that need to be transferred from one container to another can be very heavy. For example, water can weigh up to 8.3 pounds per gallon and some liquids can weigh much more depending on the density. That is is why tipping a drum can be very difficult, impractical, and unsafe. It is for this reason that many companies that purchase and handle liquid products make use of a drum pump to pump different types of fluid from larger containers to smaller ones before they are utilized. A quality drum pump can draw in liquid from a large drum and pump it into a smaller container with minimum spillage.

Drum pumps are utilized by many different types of manufacturing, chemical, food, and other processing plants that handle liquids or pasty products in large drums or totes. These processing plants make use of drum pumps as a practical way to pump smaller quantities of liquid out of large containers.
Drum pumps are designed to pump many different types of fluids that need to be transported, handled, transferred, or processed. Some of the more common industries that make use of drum pumps include:

Chemical plants
Food and Pharmaceutical plants
Manufacturing plants
Automotive shops
Other processing plants

Types of Drum Pumps

There are three main types of drum pumps:
1. Electrically operated
2. Manually operated
3. Pneumatically operated

These pumps can be used interchangeably unless they have been hardwired into the drum or barrel. This type of liquid transferring equipment is portable but can also be piped into a factory system. They are available in metallic or plastic (non-metallic) materials to minimize the risk of corrosion when pumping corrosive liquids.

How do Electrically Operated Drum Pump Models Work?

This type of drum pump is designed to fit into the top opening of a container by a narrow tube that contains a vertical shaft. The pump runs on a small AC or DC electric motor that is attached to the shaft. When the motor is switched on the pumping mechanism is activated and the content is sucked up from the base of the tube. A rotor or small centrifugal pump impeller is situated at the base of the tube to assist in the pumping action. Electrically operated drum pumps are ideal for pumping high volumes of liquid or draining large volumes of fluid. They are available in wired as well as battery-powered models with different voltages. Higher voltage models are heavier and thicker with various lever shapes and lengths.

How do Manually Operated Drum Pump Models Work?

Manually operated drum pumps are operated by a hand crank or by using a piston pump. They are normally utilized for remote pumping applications or in situations where there is little or no power available. They are available in a range of materials that include stainless steel, aluminium metals, and plastics such as PVC, polyacetal, and polyphenylene sulfide. They come in sizes ranging from half-inch to one and a half inches. These manually operated drum pumps are normally used for low-volume applications. They are ideal for applications where low cost, easy, spark-free, and leak-free pumping is required. Manually operated pumps are often approved for use in hazardous environments for safety purposes. However, in situations where the use and volume are high enough to make manual pumping impractical, the next available option would be a pneumatically operated drum pump.
