Zoeller Waste-Mate 267-0001 Sewage Pump
The Zoeller Waste-Mate 267-0001 is a heavy-duty, automatic submersible pump designed for sewage, effluent, or dewatering tasks. Rated at 1/2 HP, it is suited for both residential and commercial applications and can pass 2″ spherical solids, thanks to a plastic impeller and a non-clogging vortex design. Its float-controlled operation uses a 2-pole mechanical switch, delivering hands-off performance as water levels rise and fall. The unit’s compact form and robust construction make it a versatile option for basements, crawl spaces, or light dewatering tasks where reliability matters.
- 1/2 HP, automatic submersible
- Passes 2″ solids with plastic impeller
- Float-operated with a 2-pole switch
- Non-clogging vortex impeller design
In practical terms, this model emphasizes simplicity and durability for everyday wastewater challenges. It offers a straightforward install path for standard sump basins and can be a solid choice when you need reliable automatic pumping without a grinder mechanism. Its solid-duty construction helps it endure frequent cycling and moisture exposure typical of basement sump locations.
Acquaer 3/4HP Submersible Sewage Pump
The Acquaer 3/4HP Submersible Sewage Pump delivers strong performance for home sewage and sump basins. It features an oil-filled split-capacitor motor for efficient operation and high flow, capable of up to 6400 GPH and a vertical lift of up to 29 feet. The cast-iron casing, reinforced non-clogging vortex impeller, and 2″ NPT discharge support reliable, long-lasting service in basements or below-grade installations. The pump operates automatically via an adjustable float switch, with a standard 10-foot power cord to simplify wiring. A cautions note: it is not suitable for septic tanks or septic-tank environments.
- 6400 GPH and up to 29 ft head
- Cast iron construction; 2″ NPT discharge
- Auto/Manual float switch; 10′ power cord
- Non-septic-tank use only
With its durable build and high-flow capability, this Acquaer model is well-suited for basements that experience heavy, frequent water ingress. The manual override option can be helpful when you need control during inspection or testing, while the auto float ensures consistent operation without constant monitoring.
LANCHEZ 1HP 6600 GPH Submersible Sewage Pump
The LANCHEZ 1HP sewage ejector pump provides robust performance with a 1HP PSC copper motor and a maximum flow of about 6,600 GPH. It is designed to lift water up to 27 feet, making it a strong choice for deeper basements or challenging drainage routes. The cast-iron housing enhances durability, while built-in thermal overload protection guards the motor during dry-running or extended operation. An automatic tether float switch turns the pump on and off as water levels change, reducing energy use and maintenance needs in busy sump environments.
- 1HP PSC copper motor; up to 6,600 GPH
- Maximum 27 ft head; 2″ NPT discharge
- Cast iron body with thermal overload protection
- Automatic tether float switch
This model fits installations that demand higher flow in conjunction with moderate lift. Its solid construction makes it capable of handling frequent use in basements and crawlspaces, while the automatic control minimizes manual interventions for routine wastewater management.
Superior Pump 93020 1/2 HP Sewage Pump System
The Superior Pump 93020 represents a compact, cost-effective sewage pump system with a 1/2 HP cast-iron pump and a tether float switch. It delivers up to 4,800 GPH and can push wastewater up to 25 feet vertically, with a 2″ discharge and 2″ solids handling. The package includes a 30-gallon structural foam basin, providing a ready-to-install solution with durable components designed to withstand basement sump conditions. The reinforced impeller design helps keep solids flowing smoothly while minimizing clogs and downtime.
- 4800 GPH; up to 25 ft head

For homeowners seeking a straightforward, budget-conscious setup, this model offers reliable performance with a complete basin and essential features. Its simple configuration makes it a practical choice for standard basements or utility areas where wastewater travel paths are clear and predictable.
Buying Guide
Key Considerations When Choosing a Sewage Ejector Pump
Start with the application specifics: expected wastewater solids, required flow, and the vertical height (head) to reach the discharge point. A grinder pump (like Aquastrong) is advantageous if fibrous waste or larger solids are common, while non-grinder models excel in clean-water basements or when solids are minimal. Material matters: cast iron bodies offer durability, while stainless steel components can better resist corrosion in humid spaces. Automatic float switches provide hands-off operation, but ensure the float is appropriately positioned to avoid false starts from debris or backflow.
Grinder Pumps vs Non-Grinder Ejectors
Grinder pumps shred solids before passing them into the discharge line, reducing clogs in systems carrying heavier or fibrous waste. They typically involve higher maintenance due to the grinding chamber but can prevent blockages in long runs. Non-grinder ejectors rely on the pump’s impeller to move solids and are often quieter and simpler. Select a grinder if you anticipate wipes, towels, or other tough debris; choose a non-grinder if your wastewater is primarily graywater or small solids.
Sizing And Capacity
Accurate sizing hinges on peak drainage loads and the distance to the outlet. Heavy basements with multiple fixtures may require higher GPH and head ratings (for example, models around 6,600 GPH with heads near 27 feet). If you expect frequent simultaneous drainage from several fixtures, choose a pump rated above the estimated peak flow to avoid short cycling or insufficient pumping during storms or power outages.
Installation And Durability
Consider sump basin dimensions, discharge piping compatibility (2″ is common), and space for future maintenance. Cast iron housings offer lasting durability in wet environments, while additional protections like thermal overload switches help prevent motor burnout. For automatic operation, position the float assembly to avoid entanglement with debris. Grinder pumps may require periodic cleaning of the grinding chamber, so factor in maintenance tasks when planning the installation.
Maintenance And Longevity
Regular checks of seals, impellers, and vents support long service life. Keep the area around the sump clean to minimize debris ingress. Inspect electrical connections and confirm that the float switch moves freely without obstruction. If your system runs in below-freezing environments, ensure cords and hoses are rated for cold conditions and that the unit is protected against ice buildup that can hinder operation.
