— From Structure to Application: Choosing the Most Suitable Propulsion System
In surface and underwater Thruster systems, pump-jet Thruster has become the core power choice for many devices due to its high thrust, low noise, and excellent debris-proof performance. However, in practical applications, different users may hesitate between modular and integrated structures.
They each have their own characteristics in terms of structure, installation method, and applicable scenarios. Below, we will conduct an in-depth comparison of the two solutions from the perspectives of installation, heat dissipation, maintenance, and applicable scenarios.
I. Split-type pump-jet propulsion unit
Model: APISQUEEN BP150 15KW Split Type
Power: 15 kW
Thrust: 86 kg
Voltage: 72–86 V DC
Communication: 485
Speed: 7500 rpm
The split-type pump-jet propulsion system features a separate design for the motor and electronic speed controller (ESC).
This structure allows for more flexible installation layouts, enabling it to adapt to complex or highly customized power system requirements.
Key Features:
Flexible Deployment: The ESC can be installed independently according to available space, making it easier to adapt to large or non-standard hulls.
High Heat Dissipation Efficiency: The independent ESC has external heat dissipation, suitable for long-term high-load operation.
Convenient Maintenance: The motor and ESC can be replaced or upgraded individually, reducing maintenance costs.
Strong System Expandability: Supports RS-485 communication and can be connected to various control systems.
Applicable Scenarios:
A split-type solution is more suitable for:
▶Industrial-grade unmanned surface vessels (USVs), AUVs, ROVs, and other scientific research or engineering applications
▶Environments requiring long-term continuous operation and high heat dissipation capabilities
▶Projects with high requirements for system scalability and communication interfaces
II. Integrated Pump-Jet Propulsion Unit
Model: APISQUEEN BP150 15KW Integrated Unit
Power: 15 kW
Thrust: 93 kg
Voltage: 60–90 V DC
Communication: 485
Speed: 8000 rpm
The integrated pump-jet propulsion system combines the motor and electronic speed controller (ESC) into a single, highly enclosed structure.
This design eliminates external connections and wiring, resulting in superior overall waterproofing and system stability.
Key Features:
Easy Installation: The unit comes pre-installed as a complete module, requiring no additional assembly or wiring; basic installation can be completed by a single person.
High System Compatibility: The motor and ESC are tuned within the same system, resulting in more stable performance and more accurate communication.
Excellent Sealing and Protection: The overall structure is waterproof, suitable for long-term use in seawater.
Compact Structure: Measuring only 765×108 mm, the weight is concentrated, allowing for cleaner wiring.
Applicable Scenarios:
Integrated propulsion systems are ideal for applications requiring rapid deployment and high reliability, such as:
▶Small, high-speed platforms like electric surfboards and rescue boats
▶Applications with limited space or requiring rapid power module replacement
▶Marine environments with high requirements for waterproofing and corrosion resistance

IV. Selection Recommendations
When selecting a pump-jet propulsion system, the operating environment, spatial structure, and control requirements should be considered comprehensively:
If the project requires flexible layout, long-term high-power operation, or integration into a complex control system,
a modular pump-jet propulsion system is recommended.
If you require a compact, quick-installation, and highly reliable power system,
an integrated pump-jet propulsion system would be a more ideal choice.
V. Conclusion
Whether modular or integrated, the BP150 series pump-jet propulsion system meets the application needs of various types of underwater and surface equipment with its high-efficiency power output and superior protection performance.
The two solutions are not interchangeable, but rather professional choices for different scenarios:
Modular: Greater scalability and engineering flexibility;
Integrated: Higher integration and installation efficiency.
