Yamada NDP-40
Gas-liquid transfer capability | Lightweight and compact design
IWAKI Nordic offers air operated double diaphragm pumps from Yamada. These air-operated double diaphragm pumps can pump everything from clean water and volatile liquids to highly viscous, abrasive and chemically aggressive fluids like adhesives and asphalt.
Ten Features of a Yamada pump
- Handles a wide variety of fluids with high solids content: No close fitting or rotating parts so liquid with high solids content and/or size can be easily pumped.
- Self Priming: The Yamada pump design (incorporating internal check valves) allows for high suction lift even at dry start-up and with heavier fluids.
- Ability to run dry: No close fittings or sliding parts are at risk–the pump can run dry without damage.
- Variable flow rate and discharge pressure: Yamada pumps will run at any setting within their operating range simply by adjusting the air inlet pressure and system conditions. One pump can fit a broad spectrum of applications.
- Portable/Simple Installation: Yamada pumps transport easily to the application site. Simply connect your air supply line and liquid lines; the pump is ready to perform. There are no complex controls to install and operate.
- Dead Head: Because the discharge pressure can never exceed air inlet pressure, the discharge line can be closed with no damage or wear. The pump will simply slow down and stop.
- Shear Sensitive: The gentle nature and minimal parts contact with the liquid makes Yamada pumps an excellent choice for shear sensitive fluids.
- Explosion Proof: Yamada pumps are operated by compressed air, therefore, they are intrinsically safe.
- Submersible: If external components are compatible – Yamada pumps can be submerged in the liquid by simply running the exhaust line above the liquid level.
- Pumping efficiency remains constant: There are no rotors, gears, or pistons, which wear over time and lead to the gradual decline in performance/flow rate.
