NACHI side push device quantitative piston pump

1. Alternative Expressions

• NACHI Side Thruster Dosing Piston Pump（Dosing Pump侧重“定量输送”功能，适用于流体计量场景）
• NACHI Lateral Thruster Fixed Delivery Piston Pump（Fixed Delivery与Fixed Displacement同义，为部分行业习惯表述）

2. Product Overview

The NACHI Side Thruster Fixed Displacement Piston Pump is a core hydraulic component specifically designed for side thruster systems. It features high volumetric efficiency, excellent mechanical stability, and strong adaptability to harsh working conditions. As a positive displacement pump, it delivers a constant flow rate under varying discharge pressures, ensuring precise and reliable power supply for the side thruster’s lateral thrust output. It is widely applied in marine vessels (bow/stern thruster systems), heavy construction machinery, and industrial automation equipment that requires lateral maneuvering capability.

3. Key Features

• High Energy Efficiency：Advanced structural design ensures high volumetric and mechanical efficiency, reducing energy consumption significantly.
• Rugged Construction：Adopts wear-resistant materials and precision engineering, suitable for long-term operation in high-pressure (up to 24.5 MPa/3553 psi) and heavy-load environments.
• Compact & Adaptable：Modular design facilitates installation in limited spaces (e.g., ship bow/stern thruster compartments), supporting both left-hand and right-hand rotation to match different system configurations.
• Stable Flow Output：Fixed displacement design maintains constant flow rate, ensuring consistent lateral thrust performance of the thruster system.

4. Typical Application Scenarios

• Marine Vessels：Bow thruster (Bow Thruster) and stern thruster (Stern Thruster) systems of large/small ships, enabling precise berthing and unberthing operations without tugboat assistance.
• Construction Machinery：Lateral maneuvering systems of excavators, bulldozers, and cranes, enhancing operational flexibility in narrow construction sites.
• Industrial Equipment：Lateral positioning systems of automated production lines, ensuring accurate lateral movement of heavy workpieces.

5. Note

When using the term in technical documents, bids, or product procurement, it is recommended to use the standard expression “NACHI Side Thruster Fixed Displacement Piston Pump” for consistency with NACHI’s official product nomenclature (e.g., PVD series, PVS series piston pumps). For specific models, the full model number should be added (e.g., NACHI PVD-2B Side Thruster Fixed Displacement Piston Pump) to ensure accuracy in product matching.
