Yamada NDP-5FS Air-Operated Double Diaphragm Pump

The Yamada NDP-5FS is a compact ¼" air-operated double diaphragm (AODD) pump built to handle low-flow transfer of abrasive and corrosive fluids with maximum reliability. Featuring a stainless steel body and PTFE elastomers, this model is ideal for applications requiring chemical resistance, mechanical durability, and precise dosing in confined installations.

With a flow capacity of up to 10 litres per minute, the NDP-5FS delivers consistent, leak-free operation in critical systems such as chemical processing, electronics manufacturing, plating, and high-purity fluid transfer. Its bolted body design ensures structural integrity and leak prevention, while Yamada’s non-lubricated air valve system guarantees smooth, stall-free operation with minimal maintenance requirements.

Key Features:

• Stainless Steel Body – Exceptional resistance to corrosion and abrasion
• PTFE Elastomers – High compatibility with aggressive chemicals and solvents
• Flow Rate – Up to 10 L/min for precise, low-volume transfer
• Ultra-Compact ¼" Design – Suitable for tight spaces, skids, or OEM installations
• Non-Lubricated Air Valve – Provides reliable, oil-free, stall-free performance
• Bolted Construction – Leak-proof design for long-term durability and safety
