Progressive Cavity Pump · Pumps
Heishin NE 3-6 is a positive-displacement progressive-cavity pump. It is normally installed in a machinery, sludge, waste, fuel, sewage or process system where viscous or solids-bearing fluids require controlled transfer. Its primary purpose is to move viscous, shear-sensitive or contaminated fluids with comparatively steady volumetric delivery. Compared with centrifugal pumps, the progressive-cavity design uses a rotor and elastomeric or engineered stator and is especially sensitive to dry running and incompatible fluid chemistry. For exact ratings, dimensions, settings, materials, connection details, and variant-specific limits, refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Check suction condition, stator and rotor wear, seals, bearings, coupling and drive alignment. Prevent dry running and confirm that the pumped medium is compatible with the stator material. Trend motor load and delivered flow where available. Exact wear limits and elastomer selection require manufacturer documentation.
Carry the correct stator, rotor or rotor service kit where justified, mechanical-seal or packing kits, coupling elements, bearings, drive belts if fitted and gaskets compatible with the pumped medium.
