As trenchless technology such as Horizontal Directional Drilling (HDD) advances, complex underground conditions demand robust and efficient mud systems. To meet these rigorous engineering requirements, Weifang Shengli Petrochemical Machinery Co., Ltd. proudly introduces the 3DP Series (3DP3200 and 3DP2800). Designed specifically for heavy-duty applications, this premium Shengli Petrochemical Large-Displacement Trenchless Mud Pump delivers unmatched fluid control, serving as a powerful tool for boosting production in major pipeline crossing projects worldwide.

Core Engineering Advantages

1. Maximum Flow Rate Up to 3,200 Liters Per Minute

In large-scale HDD operations, high displacement is critical for maintaining borehole stability and flushing rock cuttings. The 3DP3200 model excels here, achieving a maximum flow rate up to 3,200 liters per minute (175 m³/h) at a rated speed of 140 spm. The 3DP2800 also provides a formidable 2,800 L/min capacity, perfectly matching the circulation needs of large drilling rigs.

2. Extremely Reliable and Durable

Trenchless worksites demand equipment that withstands harsh environments. The 3DP series utilizes a horizontal, long-stroke, three-cylinder single-acting design. This reduces the pump's stroke rate while fulfilling displacement needs, vastly extending the lifespan of vulnerable fluid-end parts. Supported by a dual forced lubrication system that reduces friction and improves heat dissipation, this diesel-driven pump remains highly reliable and durable during continuous, high-load operations.

3. Compact & Convenient for Maintain

Minimizing downtime is essential for project profitability. The 3DP series is intelligently engineered with a highly accessible, modular structure, making it exceptionally convenient for maintain. On-site engineers can easily disassemble components for quick daily maintenance. Despite its immense power, the pump maintains a compact footprint and beautiful appearance, simplifying site integration, skid mounting, and transportation.

Direct Value from the Manufacturer

With heavy-duty weights up to 8,000 kg, robust 220mm plungers, and flexible pressure ratings (up to 12 MPa), these pumps are built to last. Partnering with Weifang Shengli means securing factory-direct pricing from a trusted Chinese manufacturer, eliminating intermediary markups.
