Koshin pumps are so durable, and so easy to service, that we sell our pumps widely in the Construction Equipment Rental Industry.

Keeping rented equipment operational and in the field is key to running a profitable business, and many have had a Koshin pump in their fleet for years. With the addition of Koshin Inverters & Generators in 2023, Koshin America now offers industry leading portable power solutions as well.
