  • Safe and reliable. F class motor insulation. Trustworthy protection system with overheating and overloaded protective components, control system leakage detector installed.
  • Motor rotational shaft is made of stainless steel. Robust static and dynamic test makes the pump operate smoother. Branded bearing is applied for the driver that ensures reliable performance.
  • Three-layer mechanical seal greatly enhances the wear-resistant performance. Sealing material: tungsten carbide.
  • A dislodgement plate is fixed at the inlet of the isolated area. This drives the solid particles out of the isolated areas.
  • Alloy steel is used for the flow part. Jacket structure for easy maintenance and replacement.
  • Applied in extreme working conditions.
  • The agitation head can also be mounted if necessary to avoid the solid particles on the pond bottom from settling down. Easy adjustment on capacity. Great for model selection.
