PUMP

  • Max. immersion depth: 5m
  • Max. liquid temperature: +40°C
  • Liquid PH value: 4-10 3 3
  • Max. liquid density: 1.2x10 kg/m
  • Power Range: 0.37kW - 4kW

APPLICATION

  • Heavy duty grinder pump for pumping sewage
  • Ideal for pumping sewage and wastewater in domestic, commercial and industrial applications

FEATURES

  • Semi-open impeller design with hardened stainless steel grinding system
  • The large-diameter impeller generates a high pressure, and the grinding system grinds solids into small pieces, which can be drained without clogging the pipes
  • Heavy duty HT200 cast iron construction
  • Stainless steel shaft
  • Guide rail kits available for all models
  • Thermal overload protection

WORKING CONDITIONS

  • Liquid Temperature: 0- 40°C (32-104°F)
  • Max Immersion Depth: 5m

MOTOR

  • Frequency/Pole number: 50Hz/2
  • Insulation Class: F
  • Protection Class: IPX8
  • Heavy Duty Ball Bearings
  • Double Silicon/Carbon Mechanical Seals

REPLACEABLE CABLE DESIGN

The unique cable design reduces the maintenance cost to a minimum. If the cable is damaged, either by a grease attack or corrosion from general wear and tear, it can be easily removed and replaced without dismantling the pump. Cable sleave is epoxy resin filled for reliability.
