MSELTOS 132 GPH HVAC Condensate Pump
The MSELTOS 1/30 HP 132 GPH condensate pump is built for both household and commercial use. It features a 20 ft max lift and a high flow rate of 132 GPH, capable of handling condensate from AC units, boilers, and dehumidifiers. Automatic drainage is managed by a safety switch that prevents overflow by shutting off connected HVAC systems when needed. The built-in alarm alerts users if inflow surpasses pump capacity. Additionally, the pump comes with 3 indicator lights for power status, operation, and overflow risk, making troubleshooting intuitive and user-friendly. The compact size allows for flexible installation in tight areas.
MSELTOS Mini Sump Pump with Float Switch
This automatic mini sump pump is perfect for light-duty condensate removal with a flow rate of 55 GPH and a max lift of 5 ft. Its small footprint (2.24″ × 1.38″ × 2.2″) allows installation in limited spaces such as inside water reservoirs or small HVAC compartments. The device is equipped with double water level sensing technology: it turns on when water hits the high sensor and off on the low sensor, thus reducing unnecessary cycling. Versatile in application, it can also help manage accumulated water in basements or pool covers, not just air conditioning systems. The pump supports both 115V and 230V power standards.

Flow Rate and Pumping Capacity
The flow rate, usually measured in gallons per hour (GPH) or liters per hour (L/h), determines how much condensate the pump can handle. Choose a pump with a capacity exceeding your system’s condensate output to avoid overflow and frequent running.
Maximum Lift Height
Lift height is the maximum vertical distance the pump can move water. Assess your installation location and drainage path to pick a pump with sufficient lift height, typically ranging between 5 to 33 feet.
Power Compatibility
Check the pump’s operating voltage – common options are 115V, 230V, or universal 100-220V designs to match your regional power supply and HVAC system requirements.
Size and Installation Type
Compact designs or wall-mounted models save space and aid in easier integration within your HVAC system. Mini pumps fit in constrained spaces but may have lower capacity.
Noise Level
If the pump is located near living or working areas, opt for quiet models with noise levels under 20 dB to minimize disturbances.
Automatic Features and Safety Switches
Automatic operation with float or water level sensors prevents manual monitoring. Integrated safety switches that connect to HVAC systems help shut down the equipment during overflow, protecting your property.
Durability and Material Quality
Look for corrosion-resistant and abrasion-proof materials like solid plastics or sealed circuit boards, ensuring long-term reliability in humid environments.
Maintenance and Ease of Use
Features like removable reservoirs, indicator lights, and alarms for overflow simplify maintenance and troubleshooting for efficient upkeep.
By weighing these factors, you can select the best air conditioner drain pump tailored to your specific HVAC setup and drainage needs.
