A wide option
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.
Long running, fuel-thrifty diesels
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.
Durable construction
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.
Easy maintenance
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.
●
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: Agriculture and home
●
Higher performance over standard fresh water pumps, unique to Yanmar.
●
Handles gravel and trash below φ20mm.
●
Easy maintenance: just remove the four bolts to clean the inside of
 the casing.
●
Sic ceramic machanical seal can be used semi-permanently.
Uses: Agriculture, home, civil engineering, fishing
●
Handles water with φ20-31mm gravel.
●
Liner improves wear-resistance of the inner casing.
●
Sic ceramic mechanical seal can be used semi-permanently.
●
High chrome impeller with high durability.
●
Pump can be cleaned easily by loosening the two grip bolts.
Uses: Civil engineering, rental
●
Handles highly viscous fluid that centrifugal pumps can't pump.
●
Capable of pumping water containing
 φ25-31mm gravel and sludge.
●
The reciprocation of the diaphragm efficiently transfers the fluid.
Uses: Civil engineering, cattle disposal treatment, aqua-culture
AIR-COOLED DIESEL ENGINE L-N SERIES
The fuel injection system, the heart of a diesel, has been refined through
years of research and development at Yanmar. We have succeeded in
minimizing the weight and size of this equipment and simplifying its
structure by adoption of a bushless pump and a smaller nozzle.
●
Durable — because it is 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.
