The Main Features Of Yamada Air-Operated Diaphragm Pumps​

  • It is capable of handling many types of fluids, even with heavy solid content; the absence of rotating or close-fitting parts makes it easy to pump liquids with high mineral or other solids in them.
  • Self Priming – The internal check valve design of the Yamada pumps enables high suction lift during startup, even with heavy fluids. 
  • The pumps are capable of running dry without any damage because there are no sliding parts or close fittings that could pose a risk otherwise.
  • The pumps can be run at varying discharge pressures and flow rates – any setting within the operating range as per your requirements.
  • Yamada pumps can be easily transported to the location required and installed quickly 
  • Able to shut off the discharge line without fear of damage or deterioration as the pressure during discharge does not exceed the air inlet pressure at any time.
  • Yamada pumps are ideal for shearing sensitive liquids, which ensures minimal contact between the fluid and parts.
  • Yamada pumps can be submerged in liquid as long as you ensure that the exhaust line stays above the liquid level.
  • The absence of gears, rotors, and pistons—which are prone to wear and tear and damage with long-term use—ensures consistency in the pumping efficiency of these pumps. The flow rate and efficiency remain steady for much longer than

Why Choose Yamada Air-Operated Diaphragm Pumps?​

  • The Yamada diaphragm pumps are fully bolted, and the mating surfaces are leakproof. The fit-bolted construction also makes it easy to reassemble after maintenance servicing. 
  • The air valve concept distinguishes Yamada pumps from others, along with their being accessible from outside; this enables their inspection and servicing without stopping the pump from an operation. 
  • The pilot valve, which activates the air valve, is modular in design and maintenance-free, as there are no snap rings or greased dynamic o-rings that may need replacement or repair. 
  • The clamp bands used are also leakproof, and many Yamada pumps feature one air valve type – this helps to simplify assembly and decrease the inventory of spare parts. 
  • Owing to the continuous research, the company perfected the strength life, ensuring maximum life and performance for the diaphragm with minimal downtime or maintenance expenses.
