Where Sewage Cutter & Grinder Pumps Perform
- Sewage & Effluent
- Trade Waste & Fibrous Solids
- Commercial & Municipal Sites
- Pressure Sewer Systems
Built for abrasive slurry transfer where seal wear, solids loading and maintenance downtime are common issues.
Built for abrasive slurry transfer where seal wear, solids loading and maintenance downtime are common issues.
Best suited for:
- Sewage pumping
- Effluent transfer
- Domestic and commercial sewage systems
- Wastewater containing fibrous solids
Selection considerations:
- Confirm whether solids need cutting or finer grinding
- Check pipe diameter and discharge distance
- Match pump type to flow, head and system pressure
For sewage and effluent duties where solids reduction helps reduce downstream blockage risk.
Peristaltic hose pumps integrated into complete dosing, batching, and process skid systems.
Built for abrasive slurry transfer where seal wear, solids loading and maintenance downtime are common issues.
Best suited for:
- Long discharge lines
- Narrow pipework
- Pressure sewer applications
- Sites needing finer solids reduction before discharge
Selection considerations:
- Confirm whether a grinder is required instead of a cutter
- Check pipe diameter, discharge length and pressure requirements
- Match the pump to solids type, head and operating conditions
Useful where solids need finer reduction before being pumped through smaller, longer or more restrictive discharge lines.
Reliable for sludge feed, polymer dosing, digester systems, and dewatered solids transfer.
Built for abrasive slurry transfer where seal wear, solids loading and maintenance downtime are common issues.
Best suited for:
- Shopping centres
- Commercial buildings
- Factory estates
- Municipal sewage systems
Selection considerations:
- Check expected usage and peak wastewater load
- Consider pipework layout, access and maintenance needs
- Match automatic control options to the sump arrangement
A practical option for commercial and municipal sites where reliable sewage transfer and solids handling matter.

FAQ's
for Sewage Cutter & Grinder Pumps
-
What is the difference between cutter and grinder pumps?
Cutter pumps shred softer or fibrous solids to help prevent clogging in discharge pipework. Grinder pumps reduce solids into finer material using a radial cutter and cutter ring.
-
When should I use a sewage cutter pump?
A cutter pump may suit sewage, effluent or trade waste duties where soft or fibrous solids need shredding before discharge.
-
When should I use a sewage grinder pump?
A grinder pump may suit sewage systems where solids need finer reduction before being pumped through smaller, longer or more restrictive pipework.
-
How do I know whether a cutter or grinder pump option is right for my site?
Selection depends on solids type, pipe diameter, discharge distance, flow, head, sump layout and operating conditions.
-
Are automatic versions available?
Selected cutter and grinder models are available with automatic options in 240V and 415V, depending on the model.
