Updated: Dec 27, 2025

Welcome to Nichiboku's Industrial Blog: Your Guide to Hydraulic Power Units & Air-Acting Piston Pump Units


Introduction

Our focus keyword: Hydraulic Power Unit & Air‑Acting Piston Pump Unit. In today’s global marine and offshore industries, procurement decision-makers, engineers, and system integrators demand equipment that combines precision, durability, and internationally proven performance. The purpose of introducing the Nakakita Seisakusho Marine Fluid Control Equipment—specifically its Hydraulic Power Unit and Air‑Acting Piston Pump Unit—is to generate awareness and create lead opportunities among industrial buyers. These two units together provide essential hydraulic pressure generation for a wide range of marine control systems.

Introducing Nakakita’s state-of-the-art Hydraulic Power Unit and Air-Acting Piston Pump Unit, engineered for optimal performance in marine and offshore hydraulic systems.

Hydraulic Power Unit & Air‑Acting Piston Pump Unit: Precision Marine Fluid Control

The Nakakita Seisakusho Hydraulic Power Unit is designed for the most demanding marine fluid-control environments. It offers several key features:


  • Japanese Engineering Excellence: Engineered by Nakakita Seisakusho in Japan, the unit reflects decades of experience in the marine sector.

  • Reliable Hydraulic Power Generation: With built-in air-motor or piston-pump drive options (e.g., the Air-Acting Piston Pump Unit variant), the system drives hydraulic cylinders back and forth under precise control.

  • Marine-Ready Build: Designed for salt-air and offshore oil-and-gas conditions, with corrosion-resistant materials and seaworthy system layouts.

  • Flexible Integration: Tailorable to specific vessel or offshore platform hydraulic circuits—ideal for dynamic positioning systems, deck machinery, winch control, and more.

  • Global Service Network: With Nichiboku Tech acting as your Japanese industrial machinery partner, you gain access to Nakakita Seisakusho’s service support for global deployments.


Key Technical Benefits of Both Units

  • Precision Fluid Control: Smooth, repeatable hydraulic actuation ensures stable system performance under variable loads.

  • Robust Performance: Designed to operate under marine ambient conditions—humidity, salt creep, vibration, and extended duty cycles.

  • Ease of Maintenance: Modular components and clear access reduce downtime during scheduled shipyard or platform servicing.

  • Energy-Efficient Design: Optimized drive mechanics minimize compressed-air (or electric motor) consumption, contributing to lower operating costs.

  • Compliance & Certification Ready: Suitable for marine and offshore compliance regimes; ask our team about classification-society certificates and suitability for hazardous areas if required.


Air‑Acting Piston Pump Unit: Efficient Air-Driven Hydraulic Generation

The Air-Acting Piston Pump Unit operates by supplying air pressure to an air motor, which drives a hydraulic cylinder in a reciprocating motion to generate reliable hydraulic pressure. This unit offers:


  • Air-Powered Operation: Ideal for vessels equipped with stable compressed-air systems.

  • Compact Structural Design: Suitable for limited machinery spaces onboard.

  • Stable Hydraulic Pressure Output: Ensures smooth control performance.

  • Lower Electrical Consumption: Reduces the electrical load compared to motor-driven systems.
