Barrel pumps, also known as drum pumps, are essential for safely transferring liquids from barrels, drums, or tanks—especially when dealing with chemicals, oils, or other hazardous fluids. Choosing the right pump ensures efficiency, safety, and durability. Here’s what to consider:

1. Type of Fluid

Identify the liquid you’ll be transferring. Is it corrosive, flammable, viscous, or water-like? For corrosive chemicals, choose pumps made from PVDF, polypropylene, or stainless steel. For oils or flammables, metallic pumps with explosion-proof motors are ideal.

2. Viscosity & Flow Rate

Thicker fluids require pumps with higher torque and slower flow rates. Use electric or air-operated pumps for medium to high-viscosity liquids, and manual hand pumps for water-thin or small-volume jobs.

3. Container Size & Pump Length

Ensure the pump’s tube length matches your barrel or container height—standard drums are usually 200 liters (55 gallons) and need a 1000 mm or longer pump tube.

4. Operation Type

Decide between manual, electric, or pneumatic (air-powered) operation:

• Manual: Best for small, occasional use.

• Electric: Ideal for frequent, high-volume transfers.

• Pneumatic: Suitable for hazardous or explosive environments.

5. Safety & Compliance

Look for pumps with proper seals, grounding wires, and certifications (e.g., ATEX for explosive atmospheres) to meet workplace safety standards.
