Moves even the toughest sludge

Diaphragm Pumps | Handles highly viscous fluid that centrifugal pumps can’t pump. Capable of pumping water containing 25-31 mm gravel and sludge. The reciprocation of the diaphragm efficiently transfers the fluid.

Uses: Civil engineering, cattle disposal treatment, aqua-culture


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.
