HEISHIN M‑4B oil pump delivers reliable and efficient oil circulation with a capacity of 4 m³/h and a discharge head of 3 kg/cm², making it an excellent choice for lubrication systems, hydraulic circuits, and auxiliary oil transfer applications in industrial and marine settings. This compact rotary displacement pump ensures consistent, pulse-free flow—ideal for systems where stable oil delivery under moderate pressure is essential for protecting downstream components.
Designed for durability, the M‑4B features precision-machined internal gears and a balanced casing constructed from corrosion-resistant materials. Tight internal tolerances minimize leakage and ensure high volumetric efficiency, while dynamically balanced rotors reduce vibration and noise—benefits that protect seals, bearings, and associated piping. The pump is equipped with robust elastomeric seals and rugged bearings, offering dependable performance during continuous operation.
Installation and integration are simplified thanks to its standardized inlet/outlet ports and compact footprint. The M‑4B supports direct coupling with electric motors, hydraulic drives, or gearbox systems, making it flexible for retrofit and new installations. Its modular design incorporates quick-access service covers—allowing technicians to inspect or replace mechanical seals, bearings, and gears without full pump disassembly. This feature significantly reduces downtime and maintenance labor costs.
Combining a 4 m³/h flow rate, 3 kg/cm² head, and construction tailored for serviceability, the HEISHIN M‑4B oil pump is a smart solution for engineers and maintenance professionals focused on reliable, low-maintenance fluid handling. Whether specified for lubrication circuits, hydraulic supply lines, or auxiliary oil delivery, it delivers precise performance, straightforward integration, and long operational life—offering lasting value in critical oil management systems.
