Nachi PVS Piston Pump
- Energy-Saving Design: The pump has been designed to conserve energy. This is done through the use of a semi-circular barrel swash plate, which maintains a uniform discharge volume to prevent excess discharges or power losses, hence reducing hydraulic costs​​.
- Quiet Operation: Key parts like shoes, swash plates, and valve plates have built-in noise reduction mechanisms that make them very quiet during operation. Thus, this device is perfect for areas where noise should be minimized​​.
- Small Size and Light Weight: Also, while designing the PVS-0B model, we made sure that it was more compact and lightweight than other models so far produced, therefore contributing to the reduction of sounds produced by machines even further​​.
- Options for Adjusting Pressure: The PVS series provides different pressure adjustment ranges, from 2 to 3.5MPa to 2-7MPa, 3-14MPa, and even 3-21 MPa, to cater to different operational needs​​.
- Versatile Mounting Types: It can be mounted in various ways such as having ports located at either side or ports located axially thus allowing for system installation flexibility based on requirement​​.
- Different Mechanisms of Control: These include manual pressure compensation, remote control pressure compensation, two-pressure-two-flow rate control,solenoid cutoff control, and two cutoff control, thus enhancing operational flexibility​​.
- Longevity and Dependability : The quality materials used in constructing this pump together with its robustness (strong swash plate) coupled with durability (hardened pistons) ensure reliable performance over an extended period under harsh conditions where reliability may get compromised easily over time​​
- Convenience during Maintenance: Additionally designed with simplicity when it comes to maintenance issues so that there can always be easy access to parts plus straight forward steps followed during pressure adjustments or flow rates thereby minimizing downtimes and effort required for servicing​​.


Nachi PZS Piston Pump
- High pressure and dependability:These pumps can withstand high pressure (as much as 28 MPa) and high reliability, which makes them appropriate for use in demanding hydraulic applications.
- Low noise and vibration:It has a design that features a semi-cylindrical swash plate that enhances support and rigidity thereby allowing more pistons to be used with optimal valve plates so as to achieve quiet operation.
- High reliability & long life:To prevent oil leaks on mating surfaces, O-ring seals have been employed while spherical valve plate ensures the best balance of hydraulic pressures are maintained for stable running with improved resistance against contaminants which results into longer life span.
- Wide application range:They can be used alone or combined with other pumps like IP pumps thus making it possible for them serve different needs in terms of applications.
- Variable volume capacity:These pumps possess variable volume capability which is important in ensuring delivery rate remains constant at all times this leads to energy saving within hydraulic systems.
- Control over Pressure & Flow Rate:Offering flexibility depending on the specific requirements there are models included under PZS Series having pressure compensation, two-pressure control and two-flow mechanism for controlling pump performance.
- Strong built:With its sturdy construction design featuring high-rigidity swash plate these units will last longer even when subjected to heavy duty operations found in various industries.
