 YAMADA - diaphragm pumps
Pneumatic driven "double" diaphragm pumps can all be adapted to resist all existing chemicals. Driven by air, the pumps are intrinsically safe and to use in hazardous environments. These pumps are self-priming and the head is as much as pressure of compressed air available.
The pumps can also be applied as stand-alone emergency pump because it needs no foundation and they are GENERAL APPLICABLE.
The Yamada diaphragm Pump Program is the largest thinkable.
Pumpsize = liquid port sizes in BSP (or flange from 1.5” )
- 1/4" - max. capacity 10 liters per min. - NDP-05
- 3/8" - max. capacity 20 liters per min. - DP-10 / NDP-10
- 1/2" - max. capacity 45 liters per min. - NDP-15
- 3/4" - max. capacity 100 liters per min. - NDP-20
- 1" - max. capacity 160 liters per min. - NDP-25
- 1.5" - max. capacity 400 liters per min. - NDP-40
- 2" - max. capacity 600 liters per min. - NDP-50
- 3" - max. capacity 800 liters per min. - NDP-80

The wetted construction parts are available in polypropylene, pure PTFE, PVDF, stainless steel, aluminium or cast iron. Valves and diaphragms are available in pure PTFE, all rubbers and thermoplastics.
Besides standard pump models there is the economic Green Line, the Heavy Duty line and all PTFE for the Semi-Conductor industry.
Non-Lubricated Air Valve
The patented air valve on all NDP series pumps never requires lubrication or pre-packing. The advanced design eliminates the need for external lubrication which can lead to pumpage contamination and maintenance headaches. Yamada is proud to be the originator of non-lubricated air valve technology for air-powered double diaphragm pumps.
Non-Stalling
A patented non-centering, spring-assisted shifter is incorporated into every NDP Series pump, ensuring a positive shift every time. The 304 stainless steel C-springs provide exceptional durability and longevity and are tested to last over 300 million cycles!
