Yanmar's pump series range in bore size from 2 “ to 4 “ for fresh water, semi-trash, trash, and diaphragm models. The series can handle all types of water, from fresh to muddy sludge.

Fuel-efficient diesel pumps can be operated 1.5-4 times longer than gasoline pumps. This advantage truly shows in night time and other continuous pumping operation at sites where no commercial power is available.

The principal parts of each pump are reinforced for superior wear resistance. The trash pumps are further strengthened by adding liners to the inner casings.

Cleaning the inside of the casing can be done simply by just removing a few bolts. With trash pumps, the casing cover and the inner casing come in one block, so separation and fitting is very easy.

AIR-COOLED DIESEL ENGINE L-A SERIES

Its secret is Yanmar's micro-sized fuel injection system

The fuel injection system, the heart of a diesel, has been refined through years of researchand evelopment at Yanmar. We have succeeded in minimizing the weight and size of this equipment and simplifying its structure by adoption of a brushless pump and a smaller nozzle.

● Durable-because it built by a specialist in
large diesel technology.

● Convenient Recoil starter-a feature commonly
associated with gasoline engines.

● Fuel costs dip to a new low with Yanmar ' s
direct fuel injection system.

● Very low vibration and quiet running make it
ideal, a popular choice for constantly
operating machinery

FRESH WATER PUMP

●Light weight and compact design
●Easy maintenance: just remove the four bolts to
clean the inside of the casing.
●Meets a wide range of applications coupled with air-
cooled diesel engines. Uses: Water supply and home.

SEMI-TRASH PUMP

●Higher performance over standard fresh water pumps,
   unique to Yanmar.
●Handles gravel and trash below Φ 20mm.
●Easy maintenance: just remove the four bolts to clean
   the inside of the casing. Uses: Water supply, home, civil
   engineering, fishing.

TRASH PUMP

●Handles water with Φ 20-30mm gravel.
●Liner improves wear-resistance of the inner casing.
●Sic ceramic mechanical seal can be used semi-
permanently.
●Pump can be cleaned easily by loosening the two grip
bolts. Uses: Civil engineering, rental.
