The Nissan 21010-50K26 forklift water pump has a mechanical seal, press-fitted bearings, and is suitable for use with a Nissan forklift motor. The mechanical seal is made of carbon and ceramic for durability, to resist heat and leaks, and to help minimize noise. The water pump bearings are press-fitted with three tons of pressure for a smooth rotation. The water pump's hub is precision-manufactured to help prevent water from leaking while the motor is running. The fan vane on this water pump is manufactured to minimize cavitation, which is the formation of vapor cavities that can cause pitting. Tools for installation are sold separately.

Nissan manufactures vehicles and parts for consumer, commercial, and industrial applications. The company, founded in 1933, is headquartered in Yokohama, Kanagawa, Japan.
