Specifically designed to move bulk solids more effectively throughout your process. They are a cost effective replacement for Augers and conveyors and eliminate unsafe and labor intensive means of moving bulk powders. These heavy duty pumps consistently transfer fine-grained (100 um of finer), low density (5 to 50 lbs/cubic foot), dry powders in a dust-free operation.
Principles of Operation
- Conveying distance depends upon the micron size and te bulk density of the powder. For example fumed silica can be conveyed 150 feet while flour a maximum of 40 feet. Refer to the Yamada “Pumpable Powder” data sheet for specific materials.
- Powder must be 150 mesh (160 micron) or smaller size particle/powder and dry. The pump will not pump crystals or flakes and the bulk density should be less than 50 lbs/ cubic feet. The higher the bulk density, the shorter the conveying distance and the lower the flow rate
- The pump can be located a maximum of 15 feet above powder source
- Yamada recommends aeration/fluidization of the powder a minimum of 10 to 15 seconds prior to starting the pump-premature diaphragm, center shaft and center disk failaure can be avoided
- PTFE check balls are recommends for sticky powders
- Yamada recommends regulating compressed air to 70PSI Maximum
- Air volume requirements and capacity
