Sewage and Wastewater Pumps |SEG, SEV, and More

Managing sewage and wastewater systems is vital for households, companies, and industrial facilities. The proper pump is indispensable, no matter if it’s a home’s central septic tank, a sewage pit located beneath a motel, or a waste lift station situated on a farm. Here at Pumptastic, we specialize in providing various Australia sewage pumps under and above the ground. Our selection ranges from residential grinder units to robust industrial submersibles.

Pump Types and Applications

• Residential Grinder Pumps (Grundfos SEG): These submersible pumps are used in small sewage systems and septic setups. The Grundfos SEG series is a submersible sewage grinder pump that chops up solids in raw sewage. It’s perfect for a home or small business pit: when the toilet or sink is used, the SEG pump grinds the waste and pumps it out automatically. These pumps handle typical household effluent safely.
  

• Large Sewage Submersibles (Grundfos SEV): For bigger volumes or industrial waste, heavy-duty sewage pumps are needed. Grundfos’s SEV series are powerful submersibles designed for untreated raw sewage in “municipal, utility, and industrial applications”. These pumps have large passages (up to 100 mm) to let solids through, and they run continuously even in tough situations. They’re ideal for multi-unit buildings, large septic systems, or processing plants.
  

• Effluent and Sump Pumps (Onga and Others): If your wastewater is mostly greywater or pre-treated effluent, a simpler sump pump may suffice. Many Australians rely on pumps (like those from Onga) to move tank effluent or rainwater runoff. Onga offers cast-iron, stainless-steel sump pumps “built to withstand the most testing of conditions”. These are great for water transfer, dewatering basements, or pumping out trench drains, though they generally can’t grind solids.
  

• Lift Stations and Sewage Systems: In some cases, sewage must be lifted from below-grade pits to higher levels. Lift station pumps (also submersibles) come in packages with control panels and alarms. These systems often use the same heavy-duty pumps (SEV-type) and ensure waste is reliably moved to the main sewer.

Durability and Reliability

Working with sewage is challenging because the pumps need to operate in a vertical direction and the fluid being pumped is abrasive and corrosive. For this application, we only stock pumps designed to handle these” tough demands” with unmatched reliability, like Tsurumi, who specializes in submersible sewage pumps. They are designed to withstand the toughest conditions, incorporating cast-iron and hardened impeller construction to withstand abrasive waste. These and our pumps are designed to operate in harsh conditions and last a long time.

Moreover, Grundfos incorporates rugged motors and specialized seals onto the SEV and SEG models. To combat clogging, the SEV series uses a distinct “SuperVortex” impeller. In the same way, Onga’s products employ stainless steel and cast iron for enhanced durability. When purchasing from Pumptastic, these leading brands are guaranteed to have performed well in Australian conditions.
