Types of Weatherford HDD Pump Series
The Weatherford HDD pump series produced by our company mainly include the following types:
WEATHERFORD WDD 340 Pump
The system is specially optimized to provide sufficient and reliable lubrication to all moving parts, even under harsh conditions such as low speed operation or non-horizontal pump body installation, thereby significantly reducing wear and extending component life.
WEATHERFORD WDD 650 Pump
The power end frame of the WDD 650 is the rigid foundation of the entire pump and is designed to keep the crankshaft and crosshead perfectly aligned under great operating stress.
WEATHERFORD WDD 1100 Pump
WDD1100 uses a dual lubrication system combining forced lubrication and splash lubrication to ensure that all moving parts at the power end are adequately cooled and lubricated.
Advantages of Weatherford HDD Pump Series
High Efficiency & Cost Savings
Achieve over 90% mechanical efficiency, significantly cutting power/fuel costs.
Superior Durability & Reliability
Built with forged steel crankshafts, hardened liners, and abrasion-resistant parts, they withstand harsh conditions like corrosive fluids, H2S, and salinity, extending pump life.
Easy & Fast Maintenance
Features like front-removable pistons and interchangeable parts (except rotor/stator) reduce maintenance time, costs, and the need for specialized tools.
Versatile Fluid Handling
Designed for a wide range of challenging fluids, including abrasive, corrosive, and flammable liquids, ensuring broad application in oil & gas and industrial settings.
Applications of Weatherford HDD Pump Series
Horizontal Directional Drilling
This is the primary and core area of application of Weatherford HDD pump. The success of HDD operations relies heavily on a continuous, stable high-displacement mud cycle. The high flow rate characteristics of Weatherford HDD pump(up to 1,148 GPM) ensure efficient cleaning of the wellbore, cooling of the bit and efficient removal of cuttings in long horizontal intervals.
Deep Well & High-Volume Drilling
On land and offshore large drilling platforms, especially when drilling large size holes (such as surface or intermediate casing sections) , the rapid and effective removal of large amounts of cuttings is the key to improving drilling speed (ROP) . As a 1600HP power unit, Weatherford HDD pump can provide sufficient hydraulic horsepower to meet the needs of large displacement for such operations. It is an ideal main pump or auxiliary pump for large drilling rigs.
Well Service & Stimulation
Although ultra-high pressure fracturing is the domain of specialist pumps, the Weatherford HDD pump performs well in many wellbore service operations. Its smooth, continuous pumping characteristics make it ideal for cementing and acidizing operations, ensuring that slurry or acid is injected at a uniform rate, thereby improving the quality of the operation.
Large-scale Fluid Transfer
In addition to oil and gas drilling, the capabilities of Weatherford HDD pump are also suitable for any industrial application requiring large-scale, medium-to high-pressure fluid delivery. This includes but is not limited to mine drainage, produced water reinjection, long-distance pipeline transportation and hydraulic descaling.

Operating Instructions for Weatherford HDD Pump Series
Pressure and Flow Requirements
The pressure and flow rate required for a particular HDD operation depends on factors such as the borehole depth, diameter, and geological conditions. It is crucial to choose a pump that can meet these demands without overloading.
Fluid Compatibility
Drilling fluids vary in composition, and the chosen pump must be compatible with the specific fluid being used. Factors such as fluid viscosity, corrosiveness, and the presence of solids must be considered.
Maintenance and Reliability
High-pressure pumps in HDD operations are subject to harsh conditions and continuous use. Therefore, reliability and ease of maintenance are critical. Pumps with robust construction and readily available spare parts can minimize downtime and maintenance costs.
Energy Efficiency
Energy consumption is a significant operational cost in HDD. Pumps with higher energy efficiency can reduce overall operational expenses. Advances in pump technology have led to the development of more energy-efficient models.
