What is a Drum Pump?


A drum pump is a pump placed on or inside a drum or barrel, used to remove and transfer the liquid inside. This eliminates the need tip a heavy drum to remove the liquid or manually remove liquid using a mug or container. There are many types of Mandar Drum pumps available in different tube lengths, materials and models.

'MANDAR' Pneumatic Drum Pumps & Motorized Drum Pumps are extremely high quality and user friendly.

Pneumatic Drum pumps and Electric Drum are useful for safe and efficient handling of highly corrosive chemicals, solvents, acids, petroleum products, diesel oil, and fuel oils, plating solution, toxic chemicals etc.

Pneumatic and Electrical Drum pumps facilitate easy removal of fluids from barrels and eliminate danger of spillage, explosion hazards.

Construction of MANDAR Pneumatic Drum Pump is such that operating compressed air never gets in contact with pumped liquid.

Both the pneumatic and electrical Drum pumps can be directly inserted in to the barrel and fits on the bung hole by means of threading provided on the pump adopter. It sucks the liquid from the bottom and hence less chances of leftover material.

The Piston type pneumatic Drum pump does not have any type of motor and hence virtually zero maintenance.

How Does a Drum Pump Work?

A drum pump works by fitting into a drum by way of its narrow tube, which houses a vertical shaft. The drum pump also consists of a small motor attached to the shaft, which runs electric or air motor.
When the drum pump is actuated, its pumping mechanism comes from either the impeller which is at the base of the tube and which sucks out the content or by way of a Piston at the top.
Some drum pumps can be operated by hand, using Rotary or Piston or Diaphragm movement.
A Motorized Drum Pump consists of drive motor and pump tube suitable for the application. 

How to Choose the Right Drum pump?

The selection of a Barrel pump depends on many factors such as the chemical to be pumped, Viscosity, distance of liquid transfer, required flow rate and other parameters. Determine how the pump is going to be used to choose the right pump series, motor type, accessories and major pump type.

1. Check the compatibility of your application with the Barrel pump’s head and flow, chemical type, fluid, viscosity, size and motor.
2. Make sure the outer tube material is chemically resistant to the fluid in your drum.
3. Select an air drive motor if the liquid you are pumping is flammable or combustible.

Types of Drum pumps

There are two major types of drum pumps: hand operated drum pump or motorized drum pump ( motor can be Electric or Pneumatic)

Mandar Hand-Operated Drum Pumps

Hand-operated drum pumps, as their name suggests, are powered by hand, instead of a motor. They are ideal for remote pumping applications and in instances where there’s little to no power available. Mandar Hand pumps are available as Rotary, Piston or Diaphragm type

Mandar Motorized (Electric or Pneumatic Drum Pumps)

Motorized drum pumps are great to use for tasks that involve a higher volume transfer. They are available with Electric motor or Air motors.

Hand-Operated vs. Electric or Pneumatic Operated Drum Pumps


Hand Operated Electric Pneumatic Operated
Fluid Types Oils, diesel, gasoline, anti-freeze, kerosene, soap solutions Additives, dyes, chemicals that need blending, exhaust fluid
Volume Types Low-Medium High
Use Intervals Intermittent drainage of drums Regular drainage of drums
Working Mechanisms Must be twisted at the nozzle Can be plugged in or run on a battery

Benefits of Using a Drum pump

Drum pumps are both a practical and useful option for emptying out and transferring the liquids in drums. Other benefits of drum pumps include portability, the ability to be hard-piped into the system and that they are available in metallic and non-metallic materials to minimize corrosion when the pump is in use with corrosive liquids..
