Sewage Pump Comparisons

Sewage Pump Effluent Pump
Description Centrifugal pump with open type impeller designed to handle suspended particles Effluent pumps are used when the water being pumped may contain solids up to 2” in diameter.
Working principle The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser/casing, from where it exits. Pump in which fluid enters through the eye of an impeller and gains momentum inside the rotating vanes of the impeller and discharged through the volute casing.
Space Separate platform required to keep the assembly Kept in smaller area
Advantages
  • Preferred where raw wastewater/treated waste water from plants to be pumped
  • Better for large scale application
  • Maintenance free
  • Preferred where basement drainage / residential flooding to be done
  • Effluent pumps are used when the water being pumped may contain solids up to 2 inch in diameter
  • Trouble free performance
Disadvantages
  • Corrosion of impelled due to rough particle contact
  • Clogging
  • Heavy weight
  • Require maximum care for trouble-free operation
  • Solid particle size in limited
  • Used only for small scale application
Sewage Pump Sump Pump
Description Centrifugal pump with semi open impeller designed to handle suspended particles Small centrifugal light weight pump designed to drain the water stagnating at the basements
Working principle The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser/casing, from where it exits. Pumps the water out of the pit conveyed through the drains and discharges away from the basement of a building.
Space Requires separate platform required to keep the assembly Kept in smaller area
Application Sewage water treatment plant, Dewatering Sump pumps are used where the water table is above the foundation of a home
Advantages
  • Preferred where raw wastewater/treated waste water from plants to be pumped
  • Better for large scale application
  • Effluent pumps are used when the water being pumped may contain solids up to 3/4” in diameter
  • Maintenance free
  • Preferred where the water stagnation occurs esp. in basements, equipment rooms, etc.
  • Better for small scale application
  • A sump pump is an automatic water pump
  • Battery backup can be used in case of power cuts
Disadvantages Solid particle size is limited Proper maintenance is required Heavy weight Can be used for household application only Proper maintenance is required Can’t handle solid particles
Sewage Pump Grinder Pump
Description Centrifugal pump with open type impeller designed to handle suspended particles Grinder Pumps are designed to grind the solids from waste water into fine slurry at a high pressure and passes the slurry into the drains
Working principle The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser/casing, from where it exits. Pumps have grinding blades that grind the raw sewage into a slurry before passing it through the discharge line
Space Separate platform required to keep the assembly Kept in smaller area
Application Sewage water treatment plant, Dewatering Waste water conveyance
Advantages Preferred where raw wastewater/treated waste water from plants to be pumped Better for large scale application Effluent pumps are used when the water being pumped may contain solids up to 3/4” in diameter Preferred where the wastewater contains solid particles to be shredded into smaller particles to dispose that into sewer system Better for large scale application The pump will function automatically if the water reached its marked limit
Disadvantages Solid particle size is limited Proper maintenance is required Heavy weight Require maximum care for trouble-free operation Durability is less Needs the assistance of sewage pump to convey the slurry into sewer line
