Model: NSPi Series (NSP-10E-15V*A*-21, NSP-10E-22V1A*-21, NSP-20E-15V1A*-21, NSP-20E-22V1A*-21)
Features of NSPi Series
Easy Operation and Reliable Performance
Immediate start just by turning on the power
The inverter drive NSPi unit can be started easily just by turning on the power.
Just push a single button to operate at maximum energy savings after pressure is adjusted.
Production lines keep running
Production lines continue running even if there is trouble with the inverter because it is based on our reliable NSP unit and keeps running as a regular NSP unit.
Perfomance
Energy-saving effect
Power Consumption Reduced by Approximately 69%
(as compared to NACHI-Fujikoshi’s standard hydraulic units while dwelling)
The base NSP unit consumes about 40% less energy than NACHI-Fujikoshi’s standard hydraulic units. By adding the inverter drive we increase energy savings to approximately 69% as compared to NACHI-Fujikoshi’s standard hydraulic units.
Power rate 40% down
As compared to NACHI-Fujikoshi’s standard hydraulic units, the NSP unit cuts 25% and the inverter drive NSPi unit cuts another approximately 40% from energy bills.
Reduces annual CO2 emissions by approximately two tons
The inverter drive NSPi unit emits about 42% less CO2 than NACHI-Fujikoshi’s standard hydraulic units.
Equivalent to two hectares of forest

Precautions for use
- Turning the inverter on and off by cutting the main power supply (circuit breaker) significantly reduces the life of the inverter and should be limited to once an hour or less. Contact us if you need to start and stop operations frequently.
- Do not change the inverter’s parameter settings.
- Use a 1/2 inch diameter two meter long flexible hose rated for maximum 14 MPa working pressure to connect the hydraulic unit’s P port (discharge port) and the external manifold (or actuator).
- Maximum peak pressure (set pressure + surge pressure) must be within 14 MPa. Install a relief valve on the hydraulic circuit side to cut surges if peak pressure is higher than 14 MPa.
- Volume of leakage on external hydraulic circuits must be less than 1 L/min. Consult us if leakage on the external hydraulic circuit is greater than 1 L/min.
- The volume of hydraulic fluid in the tank must stay within the range visible on the fluid level gauge (10L tank: approximately 1.5 L, 20L tank: approximately 4L).
