Pneumatic Impulse Knocker – Type QJ
Product properties
.01application
The Pneumatic Impulse Knocker is suitable for knocking against slow-moving drums and filling or emptying stations with moving containers.
The knocker type QJ can be mounted at a distance from the rotating drum or a container. The operating principle is identical to the knocker type K, but the impact pulse is transferred to a piston rod which moves to the container. The drum or container wall is touched only briefly during beating and transmits the impact pulse.
Detailed information: see data sheet 100-130
.02Selection Chart
The Configuration Tool below provides a rough reference for selecting the adequate size and number of Pneumatic Impulse Knockers. In rotating drums, a knocker is fitted vertically from above striking at a slight angle against the direction of rotation on a traverse.

Important parameters for the selection of the right knocker:
- Thickness of the container or drum
- Material of the container or drum
- Diameter of the container or drum
- Operating temperature
- If present, insulation thickness for the selection of the mounting
- Protection type for operating environment
For the electrical components:
- Desired operating voltage
- Number of knockers
- Protection type for operating environment
For help in selecting the knocker, please send us the completed questionnaire. Any drawings, sketches or photos of existing plants are also helpful.
.04Mounting & Operation
The components shown in the picture are required for the installation and operation of the pneumatic pulse knocker:
- Electrical control for solenoid valve to desired control voltage. An existing PLC control can also be used.
- Pneumatic connectors and cables
- Maintenance unit for pressure reduction to 3.5 bar operating pressure, drainage and lubrication of the knocker is recommended.
Choose the right knocker for your application.
We have two types of knockers in our range: Our classic ‘singold’ Pneumatic Knocker Type K is suitable for many applications attaching the knocker on the silo wall. The special developed Impulse Knocker Type QJ is suitable for knocking from a distance against slow-moving drums and filling or emptying stations with moving containers.
