Powder Pump (Special specifications)

■ Can Transport Low Density Powders such as Diatomaceous Earth, Silica, Powder Coatings and Toners.
We have models that are capable of handling from 200 kg to 1500 kg per hour, with little separation phenomena or dust.

● Examples of Powders that Can be Transported
Toner/powder coatings/aerosols/silica/glass bubbles/calcium carbonate/carbon black/pesticides/medical powders/diatomaceous earth, etc.

■ Can be Installed at Low Cost Due to not Requiring Electrical Work and the Equipment Can be Simplified.
Useful for improving the work environment as it is a self-suction type and the flow rate can be controlled with ease.

■ Yamada’s Proprietary Design Air Switch Valve “C-Spool”
The air switch valve in the center section of the diaphragm pump is completely oil-free, so it does not require regular lubrication.
The operation assist using a C-spring suppresses stoppages during operation, and achieves stable operation.

◆ Air Switch Valve “C-Spool”

The C-spring Prevents Stoppages during Operation Achieves stable operation.	Equipped with a Reset Button Downtime due to pump stoppages in the case of wear of the air switch valve is kept to a minimum.

Completely Oil-free Both the air switch valve and the pilot valve that activates the air switch valve at the stroke limit are designed to be oil-free. Does not require regular lubrication.	Simple Replacement No need to disassemble the pump when replacing it.
