Configuration review

Sewage Grinder Pump selection requirements

Specify the operating requirement before selecting a model.

Define the selected configuration

A submerged sewage pump with a cutting mechanism ahead of the hydraulic end. Review the wastewater, fibrous waste and discharge system together before choosing the cutter and pump duty.

  • Wastewater composition, fibres and hard debris
  • Required flow and total head
  • Wet-well dimensions and operating levels
  • Discharge pipe length and diameter
  • Power supply, protection and service access

Request model-specific data

Request a hydraulic curve, arrangement drawing, wetted-material schedule and operating instructions for the proposed configuration. Broad public ranges do not establish a combined duty point.

overview

Sewage Grinder Pump construction and operation

Sewage Grinder Pump: illustrative pump assembly and construction

Submersible sewage pump with an inlet cutting assembly

The hydraulic end and motor operate below the liquid surface. Confirm the required flow and head together with submergence, cooling conditions, cable routing and lifting access.

A submerged sewage pump with a cutting mechanism ahead of the hydraulic end. Review the wastewater, fibrous waste and discharge system together before choosing the cutter and pump duty.

  • A cutting assembly reduces fibrous waste before it reaches the impeller
  • Different from a non-clog sewage pump that relies on solids passage alone
  • Cutter access and wear inspection belong in the maintenance plan

applications

Typical applications

Application illustration: municipal wastewater treatment

Commercial wastewater collection

For commercial wastewater collection, check the applicable product curve, liquid properties, required operating point and installation geometry. Check the proposed arrangement against wet-well installation with accessible lifting and discharge connections and cutter, impeller and casing materials selected for sewage and wear, then verify the operating point on the selected model curve.

Pressure sewage transfer

For pressure sewage transfer, provide inlet pressure, target outlet pressure, peak demand, control method and the number of operating zones. Check the proposed arrangement against wet-well installation with accessible lifting and discharge connections and cutter, impeller and casing materials selected for sewage and wear, then verify the operating point on the selected model curve.

Fibrous wastewater handling

For fibrous wastewater handling, check the applicable product curve, liquid properties, required operating point and installation geometry. Check the proposed arrangement against wet-well installation with accessible lifting and discharge connections and cutter, impeller and casing materials selected for sewage and wear, then verify the operating point on the selected model curve.
