Yamada NDP-80 air-operated diaphragm pump, 3", up to 814 L/min

Yamada NDP-80 is the top of the air-operated double diaphragm pump range by flow: the standard NDP-80 series delivers up to 215 gpm (~814 L/min) with a 3" port. It is intended for large lines.

Air-operated; the pump tolerates dry running, is self-priming and can run against a closed discharge. The stainless steel NDP-800 series delivers up to 305 gpm (~1155 L/min). A high-pressure HP 2:1 version is available.

Key features:

• 3" port, flow up to 814 L/min
• Dry running, self-priming, closed discharge operation
• Stainless steel NDP-800 — up to 1155 L/min
• HP 2:1 version available

Specifications:

• Type: AODD
• Flow NDP-80: up to 215 gpm (~814 L/min)
• Flow NDP-800: up to 305 gpm (~1155 L/min)
• Port: 3"
• Air pressure: 1.4–7 bar
• Options: HP 2:1

Application: High-volume liquid transfer on large industrial lines.

Before ordering: Before ordering, specify the pumped liquid and its temperature, required flow and pressure, and the body and diaphragm materials — this combination in the model code determines chemical resistance, permissible temperature and pump weight.
