Yamada Trial Pump Program

3/8" & 1/2" Fluid Ports

DP-10 series 3/8" AODD pumps provide a maximum flow rate of 6 GPM and are available in Aluminum, Stainless Steel (316) and Polypropylene.

DP-15 series 1/2" AODD pumps provide a maximum flow rate of 7.4 GPM and are available in Polypropylene and Groundable Acetal.

G15 Global Series 1/2" AODD pumps provide a maximum flow rate of 16.6 GPM and are available in Aluminum, Stainless Steel (316), Pure Polypropylene and Kymar.

We offer a wide selection of diaphragm materials that cover a variety of applications.

The NDP series pumps utilize a C-Spool.

What separates Yamada from the rest of the pack is our air valve technology. Yamada NDP series pumps use a completely non-lubricated main air valve and independent pilot mechanisms to control the air logic.

As compressed air enters the pump, it is directed via the main air valve to one side or the other, depending upon the starting position of the c-spool.  As the air enters the chamber, it forces the diaphragm outward. This outward momentum forces liquid out of the discharge ball valve and loads the opposite inlet ball valve. As the diaphragm travels outward, the connected diaphragm on the opposite side is pulling the diaphragm inward.

When it travels a full stroke, it will contact the pilot valve, depressing it and breaking the seal to open an exhaust port.

The open port allows the compressed air to the exhaust from the back side of the air valve. The pressure drop produces a shift of the main air valve. This motion simply repeats on the other side.

The Global Series pumps utilize a Step Spool (S-Spool).

Yamada Global Series pumps do not have an independent pilot valve system (less parts) and consume less air versus the competition. Available with multiport options, these AODD pumps perform extremely well in continous stop/start operations and provide exceptional suction lift.

The Yamada Advantage

Yamada Air Powered Double Diaphragm Pumps: Engineered for High Performance. Manufactured for Long Life.

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.

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.

Unified Air Valve Concept

Common-size air valve assemblies reduce parts confusion and inventory.

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.

Patented Air Valve Technology

Incorporated in every Yamada Air Powered Double Diaphragm pump

Yamada air valve technology is the heart of the air-powered double diaphragm pump and determines reliability. Yamada holds three patents on its field proven valve and enjoys a superior reputation throughout the industry.
