Advantages of DL HDD Pump Series
Advanced Fluid End Design for Unmatched Durability
The DL HDD pump's fluid end boasts a robust structure capable of enduring high pressure and corrosive fluids over extended periods. Its material selection and design are focused on minimizing stress concentration, ensuring long-term reliability in high-intensity operations.
High-Efficiency Power End Ensuring Stable and Reliable Operation
The power end plays a crucial role in smoothly and reliably transmitting power to the fluid end. The DL HDD pump's power end design emphasizes mechanical efficiency and long-term operational reliability, typically featuring a high-strength cast iron frame and precisely manufactured drive components, ensuring mechanical efficiency of up to 90%.
Robust Sealing System Guaranteeing Excellent Leak-Free Integrity
Advanced packing and sealing technologies are crucial for preventing leaks, reducing maintenance, and ensuring safe operation. The DL HDD pump features a multi-layer V-packing (chevron) design, with options for spring-loaded or gland-adjusted methods, ensuring long-lasting sealing effectiveness.
User-Friendly and Easy-Maintenance Design
The DL HDD pump is designed with ease of maintenance in mind, featuring easily removable valve covers and packing glands, allowing users to quickly inspect, maintain, and replace wear parts. This effectively reduces operating costs and enhances equipment availability.

Mud Pumping In Oil And Gas Drilling
Efficiently and reliably pumps bentonite mud, polymer drilling fluids, and other drilling media in horizontal directional drilling (HDD) and conventional oil and gas drilling operations.
Mine Dewatering And Slurry Transportation
Suitable for underground mine dewatering, tailings transportation, and long-distance pumping of various high-concentration slurries.
Industrial Cleaning And High-Pressure Operations
Provides high-pressure water jet cleaning power for large equipment, pipelines, heat exchangers, and other industrial applications requiring high-pressure fluids.
Other High-Pressure, Abrasive Fluid Transportation
Widely used in chemical, metallurgical, municipal engineering, and other fields that demand extremely high wear resistance and reliability from pumps.
New Technology in the DL HDD Pump Series
Digital video surveillance system
Intelligent sensors can measure various parameters such as vibration, temperature and pressure and can be controlled via a central control system.
Improved design to reduce power consumption
New development trends include the use of lighter and more durable materials, new cylinder designs, and intelligent speed control.
Improvement of hydraulic efficiency
