Yamada HP 2:1 high-pressure diaphragm pump, up to 12.4 bar

Yamada HP pumps with a 2:1 pressure ratio deliver discharge pressure up to 180 psi (12.4 bar) at 7 bar air pressure. They are used for filter press feeding and for transferring viscous media and slurries.

The HP version is built on NDP-20, NDP-25, NDP-40, NDP-50, NDP-80 and DP-50 pumps (NDP-20-HP, NDP-25-HP, NDP-40-HP, NDP-50-HP, NDP-80-HP, DP-50-HP). Range flow is 1 to 100 gpm depending on size.

Key features:

• 2:1 pressure ratio
• Discharge pressure up to 12.4 bar at 7 bar air
• Sizes from NDP-20 to NDP-80
• For filter presses and viscous media

Specifications:

• Type: AODD 2:1
• Discharge pressure: up to 180 psi (12.4 bar)
• Air pressure: up to 100 psi (7 bar)
• Flow: 1–100 gpm depending on model
• Base models: NDP-20, NDP-25, NDP-40, NDP-50, NDP-80, DP-50 (-HP)

Application: Filter press feeding, transfer of viscous media and slurries.

Before ordering: Before ordering, specify the base size, required discharge pressure and flow, body and diaphragm materials. Calculate compressed air consumption with a margin.
