Yamada DP20-F Plastic cased Air Operated Diaphragm Pump

This is an Air-Operated Double Diaphragm Pump Yamada F-Series Clean Room Manufactured pumps are specifically designed for the safe and efficient transfer of Ultra High-Purity Process Chemistries. They provide maximum corrosion resistance, ultra high-purity levels and low particle generation. The pump includes a 100% machined virgin PTFE diaphragm, liquid chamber and manifold. 

 

 

The patented air valve on all Yamada F-Series pumps never requires lubrication or pre-packing. Plus, it is easily accessible without disassembling the pump.

 

To ensure maximum corrosion resistance, purity levels and low particle generation, Yamada pumps feature diaphragms, liquid chambers and manifolds that are machined from 100% virgin PTFE.

Polypropylene and High Density Polyethylene are used in the air motor section (non-wetted) to ensure resistance in a corrosive environment.

 

All Yamada F-Series diaphragms are manufactured from 100% virgin PTFE. As a result, these diaphragms will last up to twice as long as those found in many competitive pumps. In addition, incorporating minimal shaft travel reduces pump pulsation. 

 

Air operation eliminates a potential source of ignition, so there’s no need to take additional preventative measures when pumping volatile or

flammable liquids or when using the pump
