Product Overview

The H Series is a heavy-duty right-angle gear drive engineered for versatility. It connects horizontal prime movers (diesel engines, electric motors, steam turbines) to vertical axis machines. With a wide range of transmission ratios, it ensures precise speed control for deep well, axial flow, and diagonal flow pumps in various climatic conditions.

Product Features

Right-Angle Transmission: Converts horizontal rotation from the prime mover into vertical rotation for the pump, offering an economical and space-saving layout compared to vertical motor installations.
Integrated Axial Load Support: Engineered with heavy-duty thrust bearings to directly support the vertical axial forces generated by the pump, simplifying the overall machine structure by removing the need for external thrust stands.
Broad Compatibility: Perfectly matches with various power sources including diesel engines, horizontal motors, and steam turbines.
All-Weather Performance: Built with a rugged housing and sealing system suitable for diverse climatic conditions, from humid marine environments to dusty mining sites.
Flexible Ratios: Available in a variety of models and gear ratios to accommodate both high-speed and low-speed requirements of different prime movers and pumps.

Product Advantages

Structural Simplicity: By absorbing the pump's axial thrust directly within the drive unit, it eliminates the need for complex intermediate structures, reducing installation time and maintenance costs.

Operational Reliability: Designed for continuous duty in harsh environments, ensuring stable water supply for critical applications like fire control and municipal waterworks.

Versatile Speed Matching: Whether you need to reduce speed for a large mixed-flow pump or match a high-speed turbine, the wide selection of gear ratios ensures optimal pump performance.

Economical & Compact: The right-angle design allows for a lower center of gravity and a more compact station footprint compared to vertical motor direct-drives, saving on infrastructure costs.
