■Variable-volume Piston Pump Unit ■Indoor Installation Type (Unit) ■Explosion-proof Type Driven by the rotary motion of an electric motor, this pump has a mechanism that automatically adjusts the discharge volume according to the pressure in the hydraulic piping. When the pump discharge pressure approaches the set pressure, the discharge volume is automatically reduced to the minimum volume required to maintain the hydraulic pressure. The discharge pressure and discharge volume are adjustable. Supplying air pressure to the air motor causes the hydraulic cylinder to reciprocate and generate hydraulic pressure. This hand pump is used to generate hydraulic pressure by reciprocating a hydraulic cylinder through manual operation of the handle. It is mainly used in emergencies, such as when the hydraulically driven valve cannot be operated due to electrical or hydraulic line problems. One-touch couplings allow quick connection. This is used to generate hydraulic pressure with a gear pump driven by manual operation of the handle. Since it is mainly installed on deck and operated manually, it is applied to valves that are operated infrequently. Driven by the rotary motion of an electric motor, as the vane passes the cam ring surface, the discharge volume goes from minimum to maximum in the suction process and from maximum to minimum in the discharge process, thus discharging a continuous ow of oil. Consisting of a vane pump, accumulator, and unload valve, it performs repeated load/no-load operation to maintain hydraulic pressure. ■Fixed-volume Vane Pump Unit Customized shapes, pipe directions, ttings, and paint colors are available upon request to meet installation conditions and applications. ■Hand Pump ■MH Operator ■Pneumatic Piston Pump Unit ■ Nakakita also offers explosion-proof equipment for special environments. The use of electrical equipment is restricted from explosion protection standpoints on ships (oil tankers, LNG carriers, etc.) that handle ammable uids such as crude oil and natural gas. Our intrinsically safe explosion-proof equipment has obtained the IECEx explosion-proof certi cation, which enables the installation of electrical equipment in each hazardous compartment, such as exposure decks and pump rooms.
