 Oil pumps |
|
 Yamada offers oil pumps with rotors having external diameters from Φ23ｍｍ~Φ90ｍｍ. This allows us to cover nearly all of the flow requirements for most oil pumps used in automobile engines.
Pump types meet a wide variety of needs and specificationary, line those connected directly to the crankshaft, those located apart from and connected indirectry to the crankshaft, etc.
Also, by designing mechanisms to prevent cavitation deterioration, we are able to recover flow deterionation at high r.p.m., improve efficiency and durability and provide Pumps that are, smaller, quieter and less expensive than the competion.

| Water pumps |
|
 Water pumps are responsible for circulating cooling water throughout the engine in order to maintain the most appropriate temperatures for each part of the engine. We have developed a bladed-wheel impeller form that achieve high performance and high efficiency. Yamada manufactures pumps for light motor vehicles (with displacements of less than 500 cc) as well as larger vehicles in our factories located in Japan, the United States, England and Thailand.
