Battery drum pump – FAQs

A battery drum pump is a portable, cordless solution for transferring common liquids from barrels, IBCs and containers. Unlike mains-powered or pneumatic pumps, they do not require an external power source, making them ideal for remote locations, outdoor use, or applications where trailing cables can create a trip hazard. An ideal solution for emptying smaller containers containing dilute acids, alkalis, oils and disinfectants, these pumps are in use with water authorities, hospitals, laboratories, swimming pools and also chemical processing plants throughout the world. 

The lightweight motor weighs only 1.2 Kg and the ergonomic design allows one-handed operation, therefore reducing risk of operator injury and making it comfortable for prolonged use. The brushless motor technology ensures consistent performance with minimal wear and tear. This results in longer service life, reduced maintenance and increased reliability. Additionally, variable speed control allows the user to vary the flow rate and improve dispensing control, thereby reducing waste and improving productivity. Furthermore, the modular design lets you use the same motor with various pump tubes, providing a cost-effective and adaptable solution for different filling and dispensing operations. 

Battery pumps will of course, be limited by battery life.  Even the best battery pack has a finite run time. Pumping high-density or higher viscosity products over 250 mPas will also negatively impact battery life, as will pumping high vertical and / or  long horizontal distances.  

For example, battery life is reduced by more than 50% when transferring concentrated Sulphuric Acid with an S.G. of 1.84. In addition, battery motors are not suitable for use with high viscosity barrel pumps, due to the high torque loads required, especially when pumping adhesive, sticky media.  

At maximum motor speed (15,000 RPM), this battery drum pump can empty a drum containing 200-litres of water in just 3 minutes. When operated at low speed (5,000 RPM), over 3000 litres can be pumped on a single charge. That’s over fifteen 200-litre drums! Furthermore, the high-efficiency brushless motor guarantees uninterrupted operation, even in demanding environments. 

As with many electric barrel pumps, a rechargeable drum pump consists of two main components, the battery motor and also the pump tube. The motor drives the rotary pumping mechanism inside the pump tube. Most common battery powered drum pumps are centrifugal designs.  

In this case, a rotating bladed impeller is mounted in the end of the pump tube. The impeller attaches to a long driveshaft that passes through the centre of the pump tube. A series of bearings support the driveshaft. The impeller rotates at high speed, thereby applying centrifugal force to the liquid and generating flow.  

The impeller must be immersed in the fluid in order to create flow. The pump cannot “suck up” the liquid, as it does not create a vacuum. It is not a self-priming pump. Operation relies on the force applied by atmospheric pressure to push liquid to the impeller. 

Assuming a battery drum pump is suitable for the application, ie. performance and liquid compatibility have been checked, you should consider the following points in order to select the most appropriate pump: 

  • Working environment – Is the motor sealed to prevent ingress of corrosive fumes (if required)?  
  • Battery life – Does the stated run time suit your needs? 
  • Charging time – How long will I need to wait for the battery to charge? Perhaps a spare battery is required to minimise operational down-time. 
  • Adjustable speed control – Is dispensing control required, eg. for filling smaller containers? 
  • Ergonomics – Is the pump light enough? Is one-handed operation required? 
  • Design features – Is the pump tube designed for long service life, or is it disposable? Are there any unique design elements that help ensure the pump handles industrial use? 
  • Modularity and flexibility – Can one motor be used with several pump tubes? 
  • Safety – Consider if the motor meets the relevant safety standards eg. UKCA, CE, UL. 
  • Durability – Are the pump and motor robust enough for their intended use? 
  • Spare parts  and accessories – Can spare parts and accessories such as hoses, hose clamps and hand nozzles be sourced quickly and easily? 
  • Repairs – Can the pump be repaired locally if required?
