Powder Diaphragm Pumps
Yamada® Diaphragm Powder Pumps
Series BH-3
Series BH-2
Yamada® Powder Pumps have been engineered to provide superior movement of bulk solids within your manufacturing process. These pumps offer a cost-effective alternative to traditional conveyors and augers while also eliminating hazardous and strenuous methods of transferring bulk powders. With their robust construction, these pumps deliver consistent and reliable transfer of fine-grained (100um or finer), low bulk density (5 to 50 lbs./cubic foot), dry powders in a dust-free environment.

Principles of Operation
- Conveying distance depends upon the micron size and the 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 Powders” data sheet for specific materials.
- Powder must be 150 mesh (106 micron) or smaller size particle / powder and dry. The Pump will not pump crystals or flakes and the bulk density should be less than 50lbs / 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 failure can be avoided.
- PTFE check balls are recommend for sticky powders.
- Yamada recommends regulating compressed air to 70PSI Maximum.
- Air volume requirements & capacity
