Struggling with flow pulsation, seal leakage and unstable pressure while transferring hot asphalt and high‑viscosity oil? Our RCB LQB internal gear oil pump is engineered for these tough industrial conditions. Adopting herringbone internal‑meshed gear structure, this asphalt insulation gear pump provides consistent pulse‑free flow. It supports 10‑1500 cSt viscosity,‑10℃ to 200℃ working temperature and 0.6‑2.5 MPa operating pressure. Featuring compact design, anti‑leak sealing and long continuous running capability, it serves petrochemical, shipping, machinery and food processing projects.
Pulse‑free stable flow: Internal herringbone gear eliminates flow fluctuation for accurate liquid transfer
Broad media adaptability: Handles hot oil, asphalt, diesel, lubricating oil and other viscous fluids
High temperature & pressure resistance: Reliable performance under‑10℃‑200℃ within 0.6‑2.5 MPa
Customizable sealing options: Carbon, ceramic and stainless steel seals prevent medium leakage
Flexible installation: Horizontal and vertical mounting fit various on‑site layout demands
Low maintenance: Simple structure for quick disassembly and part replacement, cut operating cost
This industrial viscous liquid transfer pump works across multiple harsh environments. In petrochemical plants, it transfers asphalt, hot oil and fuel oil. For machinery and shipping industry, it circulates lubricating oil and hydraulic oil. It also applies to food processing and other manufacturing for heavy‑oil conveying.
Power Range: 0.37kW‑110kW Flow Rate: 7‑500m³/h Pressure: 0.6‑2.5MPa Viscosity: 10‑1500cSt Temperature:‑10℃‑200℃ Connection: Flange / Thread
All RCB LQB gear oil pumps go through strict factory testing. Compared with regular external gear pumps, our unit runs quieter with less pulsation and longer service life. We support customization on pump material, seal type and voltage. Our technical team offers parameter matching guidance and complete after‑sales support.
