Yamada Pumps
Yamada: Engineered for Performance, Designed for LifeMating Surfaces
All Yamada pumps incorporate bolted construction, which eliminates leaks and simplifies reassembly after maintenance. Many competitors utilise clamp band construction, which frequently requires frustrating and unnecessary rebuilds due to leakage from misalignment during reassembly.
Outside Accessible Air Valve
Inspection or maintenance of every Yamada air valve may be performed without removing the pump from service.
Unified Air Valve Concept (Link)
Common size air valve assemblies reduce parts confusion.
Pilot Valve
Unique to the Yamada design is an individual modular pilot valves that actuates the air valve. It is depressed slightly by the inner centre disk creating a pressure drop at one end of the air valve, allowing shifting to occur. It is maintenance free with no cumbersome snap rings or lubricated dynamic o-rings to replace or repair.
Diaphragm Dynamics
Extensive research had led to the development of an optimal stroke length that maximizes diaphragm, like and performance while minimizing downtime and maintenance costs.
Why Choose A Yamada Air-Powered Double Diaphragm 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. | 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. |
Self Priming: The Yamada pump design (incorporating internal check valves) allows for high suction lift even at dry start-up and with heavier fluids. | Shear sensitive: The gentle nature and minimal parts contact with the liquid makes Yamada pumps an excellent choice for shear sensitive fluids. |
Ability to run dry: No close fittings or sliding parts are at risk–the pump can run dry without damage. | Explosion Proof: Yamada pumps are operated by compressed air, therefore, they are intrinsically safe. |
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. | Submersible: If external components are compatible–Yamada pumps can be submerged in the liquid by simply running the exhaust line above the liquid level. |
| 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. | 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. |
