Heishin NE Series
Heishin Heishin NE Series is identified in the source list as a progressive-cavity pump. It is normally installed in sludge, sewage, waste-oil or other viscous-fluid systems where a steady positive-displacement flow is required. Its purpose is to move viscous, shear-sensitive or solids-bearing fluids through shipboard treatment and transfer systems. The existing database record provides no additional model-specific operating figure beyond the listed designation and category. A helical rotor operating inside an elastomeric or otherwise matched stator forms progressing cavities, making rotor and stator condition central to performance. The exact model designation distinguishes rotor/stator size and installation configuration; capacity and pressure capability must be confirmed from the manufacturer documentation.

Service & Maintenance
Confirm free suction flow before starting and avoid dry running. Inspect the stator, rotor, joints, seals, coupling and drive for wear, leakage and abnormal temperature. Trend delivery, discharge pressure and motor load because increasing slip or restriction can indicate internal wear or blockage. Flush the pump when required by the handled medium and vessel procedure. Check elastomer compatibility with the actual fluid before replacing the stator. Refer to the manufacturer documentation for the exact wear criteria and assembly settings.
