The twin gear pump features a modular combined structure (R25/16 + R25/26) that enables dual-flow output, meeting the zoned oil supply requirements of complex hydraulic systems. Its core design highlights include:
Floating Bushing with Automatic Compensation: The axial clearance adjusts adaptively with pressure, reducing internal leakage and maintaining stable flow under high pressure of 25 bar.
Wear-Resistant Reinforced Components:
Housing: High-strength grey cast iron (EN-GJL-250/GG-25), with a pressure resistance exceeding 30 MPa
Gears: Hardened surface carburized steel (16MnCrS5), precision-ground to reduce meshing noise
Sealing Configuration: Standard radial shaft seals (RWDR), with customizable fluororubber oil seals (high-temperature/corrosion-resistant media compatible).
The model suffix "DB16-SO" indicates the integration of a pressure relief valve (DB16 type) and a special interface (SO), making it suitable for safety-sensitive systems.
Efficient Dual-Flow Output
The primary pump (16 cm³/rev) and secondary pump (26 cm³/rev) operate independently, simultaneously driving hydraulic actuators and lubrication systems, reducing system energy consumption by 30% (compared to single-pump multi-way valve solutions).
Long-Lasting Maintenance-Free Design
Self-lubricating bearings: Rely on media lubrication, eliminating the need for additional oiling
Pressure relief protection: The DB16 valve prevents overloading, avoiding sudden shutdown damage
Environmental Adaptability
Optimized tooth profile for low noise (≤65 dB(A))
Corrosion-resistant coating (RAL 6011 standard) resistant to salt spray/chemical environments
