Product Description
Product Overview
The DP series horizontal multi-stage centrifugal pumps are single-suction, multi-stage, self-balancing pumps designed as replacements for D-type horizontal multi-stage pumps. These industrial pumps feature a wide operating range, excellent cavitation performance, stable operation, minimal wearing parts, high reliability, and low maintenance costs. Models with an "S" suffix incorporate a first-stage double-suction structure for enhanced cavitation performance.
These products comply with GB/T5657 Technical Conditions for Centrifugal Pumps (III) Type, MT/T114-2005 Multi-stage Centrifugal Pumps for Coal Mines, and GB/T3216 Acceptance Tests for Rotodynamic Pumps - Grade 1, Grade 2 and Grade 3.
Product Applications
- DP-type: Transporting clean water without solid particles (temperature below 80°C) or liquids with similar physical/chemical properties
- DP-M type: Handling neutral mine water and similar sewage with solid particle content ≤1.5%, particle size ≤1.3mm, temperature below 80°C
- DP-F type: Transporting corrosive liquids without solid particles (temperature below 80°C) with material selection based on medium
- DP-Y type: Moving oil-based media without solid particles (temperature below 80°C, viscosity less than 120 centistokes)
- DP-R type: Handling clean water without solid particles (temperature not exceeding 105°C)
Product Features
- Self-Balancing Design: Symmetrically-arranged impellers cancel axial forces, eliminating need for balance disc structure
- Advanced Technology: Throttle pressure-reducing device reduces leakage and improves efficiency
- Reliable Sealing: Balance structure prevents excessive pressure in mechanical seal and packing chambers
- Superior Cavitation Resistance: First-stage impeller and double-suction impeller designs with reliable materials
- Stable Mechanical Seal: No axial movement of pump rotor ensures reliable mechanical seal performance
- Low Maintenance: Elimination of failure-prone balance disc structure reduces maintenance frequency and costs
- High Efficiency: Properly centered impellers and diffusers prevent efficiency decline from wear
- Media Versatility: Material customization enables handling of solid particles, oil, and corrosive substances

Structural Design
First-Stage Single-Suction Structure
For self-balancing multi-stage centrifugal pumps with first-stage single-suction structure, the suction port is horizontal (vertically upward for DP-R), and the discharge port is vertically upward. Pump sections are connected via tightening bolts, allowing head adjustment by modifying the number of stages.
First-Stage Double-Suction Structure
The first-stage double-suction impeller minimizes net positive suction head requirements and enhances cavitation resistance. Suction port is horizontal (vertically upward for DP-R), with vertically upward discharge port.
