Compact Variable Pump Unit NSP Series

Product catalog summary
Overview: The document outlines the technical specifications and operational guidelines for the NSP Series hydraulic units, emphasizing energy efficiency, compact design, and ease of maintenance. Key areas include motor selection, dimensions, and performance characteristics.
Specifications: The NSP Series integrates a variable vane pump with a motor, achieving approximately 40% energy savings over standard units. Available motor outputs are 0.75 kW, 1.5 kW, and 2.2 kW, with tank capacities of 10, 20, and optionally 30 liters. The maximum pressure is 8.0 MPa (1,158 psi). The units use ISO VG32 oil, operate at 1800 min-1, and are designed for room temperatures of 29°C.
Performance Characteristics: Designed for high efficiency and low heat generation, the units support precise machine operations and require minimal oil, contributing to resource savings. Power consumption, oil temperature characteristics, and noise levels are specified under certain conditions, with a maximum peak pressure of 14 MPa (2027 psi).
Motor Selection: Guidelines are provided for selecting the appropriate motor based on pressure and discharge rate requirements, with an example for a motor at 3.5 MPa (507 psi) and a discharge rate of 12 liters/min at 60 Hz.
Dimensions and Weight: Detailed dimensions are provided for various models, with weights ranging from 36 kg to 51 kg, depending on the model and configuration.
Installation and Maintenance: The compact design reduces installation space, and the simple structure facilitates easy handling and maintenance. Guidelines for circuit configuration and manifold block mounting are included, emphasizing pressure management and proper piping arrangements.
Energy Efficiency: The NSP Series is highlighted as an environmentally friendly option with significant energy savings due to improved design and efficient layout, suitable for machine tool power sources.
Precautions and Recommendations: Recommendations include the combination of pump and motor capacities, painting specifications, and the use of relief valves for pressure management. Design numbers may change without prior notice.
Notes: A significant rise in oil temperature is noted for a 1.10-liter tank at 5.0 MPa (724 psi) under continuous operation, recommending a 20-liter tank. Oil temperature rise varies with machine usage conditions.
Block Types and Weights: Types include F1, R1, F2, R2, F3, with weights ranging from 4.5 kg to 8.5 kg. Allowance for additional mounting is specified.
Startup Precautions: Ensure the tank is filled with hydraulic oil to the specified level, correct electric connection to avoid reverse motor pump rotation, and remove air from the pump and suction pipe by starting and stopping the motor.
Pressure and Discharge Rate Adjustment: Use the pressure gauge and adjusting screws for adjustments.
Maintenance and Inspection: Maintain oil temperature between 10 to 60°C, replace hydraulic oil three months after initial operation, then annually or when contaminated, and inspect and clean the tank interior and strainer every 6 months or 4000 hours.
Ambient Temperature: Maintain between 10 to 35°C and avoid using water-soluble coolant mist.
Options and Configurations: Block B selection from types F1 through R2, optional 30-liter tank capacity, and manifold block weight should not exceed 15 kg (33.07 lbs).
Contact Information: NACHI-FUJIKOSHI CORP. and its global branches are listed for further inquiries.

Compact Variable Pump Unit NSP Series-1

Performance Characteristics Note: The noise characteristics depend on the installation floor, base conditions and the presence or absence of the surrounding substance reflecting the sound, and so may be different from the above description in some cases. ●Type combination ●Mounted manifold block qThe right-hand table Motor kW 0.75 1.5 2.2 shows the standard Pump 0A combination between 1A pumps and motors. wA tank capacity of 30 liters is optional. eThe block mounting type is provided with a shut-off plate. ●Circuit configuration qThe basic configuration comprises a NACHICCO ) as a standard product plus external (NSPmanifold (circuit). wPiping should be arranged with a sufficient deflection between the NACHICCO and external manifold. ■ We recommend use of a hose having a normal pressure of 14 MPa {2027 psi} and a length of about 1 through 2 meters (40~80 inch). ■ The maximum peak pressure (set pressure + surge pressure) should not exceed 14 MPa {2027 psi}. ■ When the pressure rises above 14 MPa {2027 psi} , install a relief valve for surge cutting on the circuit side. qWhen a manifold block (optional) is mounted on the pump, the total weight of the block and valve should not exceed 15 kg (33.07 lbs). Type of block Weight of block Allowance for additional mounting wWhen you want to install the circuit, consult our company. ●Specifications for painting qThe inner and outer sides of the tank and motor portion are provided with melamine resin baking, and the pump portion is provided with lacquer blowing. Their color conforms to Fujikoshi standard color (Munsell NO.5B6/3). wFor the color of exterior features, consult our company. Energy saving type friendly to the earth • Options 1.

For 5.0 MPa {724 psi} of a 1.10-liter tank, it should be noted that there is a big rise in oil temperature under continuous operation. In this case, we recommend use of a 20-liter tank. 2. Rise of oil temperature depends on the conditions of using an actual machine, and so may be different from the above description in some cases.

If the operation is continued, the pump may be damaged. ¡Use the pressure gauge mounted on the discharge side and make sure that pressure rises. eRepeat the procedure of starting and stopping the motor. Remove air from inside the pump and suction pipe. (You can remove air more quickly if you remove loads from the circuit.) ●Pressure and discharge rate adjustment procedure Pressure adjusting screw Pressure gauge Discharge rate adjusting screw Clockwise rotation Decrease Counterclockwise rotation Increase Clockwise rotation Up Counterclockwise rotation Down Note: Do not touch any screw except for the above-mentioned adjusting screw. ●Maintenance and inspection qOil temperature: Use it at the temperature from 10 to 60 °C . wHydraulic oil replacement interval: Replace hydraulic oil three months after the start of operation in the beginning.
