Purpose: The NSH-21-1 gear pump is based on highly reliable НШ-39 series aviation pumps and according to the technical and ergonomical parameters corresponds to the level of the best world standards. The pump is easily producible in the up-to-date production environment.

The NSH-21-1 pump is designed to deliver fluid to the hydraulic system of various mechanisms and machines. It can be used without additional alterations as the main pumps in the EB-687 and EB-717 electric lift trucks of Bulgarian production instead of the A14X and A18X pumps.

The design is peculiar for self-compensation of the gear end clearance, which considerably increases the volumetric and total efficiency, makes it possible to operate at high pressures and decreases the value of current requirements during operation on electric lift trucks.
