Special pumps

Rugged, Bolted Construction.

All Yamada pumps feature bolted construction, which eliminates leaks and simplifies post-maintenance reassembly. Bolted construction is superior to clamp band retainers, which frequently require frustrating, unnecessary leakage rebuilds from misalignment during reassembly.
Since 1905, Yamada has been at the forefront in developing the most complete line of Air-Operated Double Diaphragm (AODD) pumps in the industry. Unmatched in quality, durability and availability, there’s no questions as to why more and more industries are coming to Yamada for their pumping needs.

Outside-Accessible Air Valve
Inspection or maintenance of every Yamada air valve may be performed without removing the pump from service.  Outside accessible, making it easy to fix / inspect.
Common-size air valve assemblies reduce parts confusion.
Pilot Valve
Unique to the Yamada design is an individual modular pilot valve that actuates the air valve. It is depressed slightly by the inner center 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.

The main characteristics are:

  • They are Portable, Air Powered and a 1:1 Ratio Pump
  • They have No Mechanical Seals, Couplings or Gears
  • They can handle a Huge Variety of Fluids including almost Any Type of Chemical
  • They offer Variable Flow Rates & Variable Discharge Pressures
  • The have Excellent Solids (slurry) Handling abilities
