Hapman Tubular Drag Conveyors.

Convey product in a completely sealed system. The sprocket drive in our tubular drag conveyors slowly pulls a heavy-duty chain through a fully enclosed pipe. As the chain moves your material through the pipe there is no chance for dusting, explosions or contamination issues.

Use less energy than other conveyors. The low-horsepower motor produces the slow, steady drag that cuts your energy costs when conveying powders or bulk solids.

Move challenging materials. Our tubular drag conveyors handle high-moisture ingredients and abrasive, blended, friable, easy-to-compact or smear products without compromising quality or efficiency.

One conveyor does the work of several. A modular design means we can configure our tubular drag conveyors to move your product vertically, horizontally, at any angle and around corners. Need more than one inlet/outlet in your bulk material handling process? Add as many as you need.


The fundamental operation of tubular drag conveyors involves a chain with flights that pull material through a sealed pipe circuit. They operate at high torque/low speed, and their capacity is determined by the diameter of the flight and the speed at which the chain assembly can be pulled through the pipe. Tubular Drag Conveyors are sealed to upstream and downstream equipment by a hard flange or a flexible sleeve. The layout of these conveyors allows for pipe bends, multiple inlet and discharge points, and routing through multiple planes and in any direction.

Gentle Handling

As the material rests in-between the conveyor pucks, the material moves in an un-agitated state, providing you with the gentlest handling conveyor on the market.

Product Separation

Tubular Drag Conveyors

Since the material is conveyed in an un-agitated state, with no moving or turning of the material, you will find that there will virtually no separation of your product while it is being conveyed. This makes the Hapman Tubular Drag perfect for the applications handling pre-blended product.

Product Degradation

Your product gently rides between the pucks of the conveyor. This keeps the material from degrading on itself, or against too many external contact points, assuring you that your material will arrive at its destination in the condition needed for your process or end product.
