Yamada NDP-40 air-operated diaphragm pump, 1 1/2", up to 405 L/min

Yamada NDP-40 is a large industrial air-operated double diaphragm pump: flow up to 107 gpm (405 L/min), 1.5" NPT port or ANSI flange, solids up to 7 mm, self-priming up to 5.5 m with rubber diaphragms.

Body: aluminium, cast iron, PP, PVDF, AISI 316. For filter presses above 7 bar a high-pressure HP 2:1 version is available; for abrasive media, abrasion pads and Ultimate diaphragms.

Key features:

• 1.5" NPT port or ANSI flange, flow up to 405 L/min
• Solids up to 7 mm
• Self-priming up to 5.5 m
• Options: HP 2:1, Ultimate diaphragms, abrasion pads

Specifications:

• Type: AODD
• Flow: up to 107 gpm (405 L/min)
• Port: 1.5" NPT or ANSI flange
• Solids: up to 7 mm
• Air pressure: 1.4–7 bar
• Self-priming: up to 5.5 m
• Body material: aluminium, cast iron, PP, PVDF, AISI 316
• Options: HP 2:1, Ultimate diaphragms, abrasion pads

Application: Filter presses, slurries, effluents.

Scope of supply: Pump. For filter press duty, the HP version and AD-40 dampener are ordered separately.

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.
