NACHI UVN-1A-0A2-0.7-4-11 Hydraulic Uni Motor Pump Power Unit 4P 0.75kW

Buy online your NACHI Hydraulic Uni Motor Pump Power Unit reference UVN-1A-0A2-0.7-4-11 from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

This NACHI UVN-1A-0A2-0.7-4-11 is a compact hydraulic motor-pump power unit designed to supply pressurized oil to CNC machine-tool hydraulic circuits. It is commonly used for chuck clamping, tool clamping, pallet locking, tailstocks, and auxiliary hydraulic functions, making it a practical CNC replacement component and industrial spare part.

The integrated pump and 4-pole, 0.75 kW motor provide a compact solution for machine-tool hydraulic systems. At 1800 rpm, the unit delivers a maximum discharge rate of 14.5 L/min, with a pressure adjustment range of 1.5 to 4.0 MPa. Its foot-mounted design allows straightforward installation where the same UVN configuration is specified.

This NACHI unit is suitable for CNC lathes, machining centers, grinders, automated fixtures, and workholding systems requiring stable hydraulic pressure and flow. Before replacement, the exact model code, mounting arrangement, hydraulic ports, rotation, and electrical specifications should be checked against the existing machine documentation.

Manufactured in Japan, the UVN-1A-0A2-0.7-4-11 is suitable as a replacement unit, stocked spare, or emergency spare for maintenance and retrofit applications. Keeping a matching pump unit in inventory can help reduce downtime caused by pump wear, leakage, abnormal noise, or insufficient hydraulic pressure.

The unit can be supplied as a tested component with protected hydraulic ports and industrial packaging. Fast dispatch is available depending on inventory and destination, with worldwide shipping, obsolete-part sourcing, repair, exchange, and refurbished-unit services available when applicable.

Frequently asked questions about UVN-1A-0A2-0.7-4-11:

Is this a drop-in replacement if my machine plate lists the same UVN-1A-0A2-0.7-4-11 code?
Yes, matching the full code is the safest route for a direct swap. Verify rotation, port thread type, mounting pattern and electrical nameplate data against the original before installation.

What does 4P 0.75 kW indicate for selection?
4P identifies a four-pole motor class and 0.75 kW is the motor power rating. Using the same values helps maintain the original hydraulic flow characteristics and response time expected by the machine’s manifold.

Can it operate on 50 Hz and 60 Hz mains?
Many industrial four-pole motor-pump units are built for common 50/60 Hz supplies, with speed and flow changing accordingly. Always confirm voltage and frequency on the unit’s nameplate to match your plant power.

What symptoms suggest it is time to replace the motor-pump unit?
Persistent cavitation noise, oil leakage, slow clamp response, rising oil temperature and difficulty holding pressure are common signs. A like-for-like replacement with the same UVN code helps restore normal operation quickly.
