Aquastrong 85 GPH Condensate Pump with Safety Switch
The Aquastrong 85 GPH model combines a thermally protected motor with a vertical centrifugal design to deliver up to 85 gallons per hour and lift water up to 20 feet. It features a robust hall switch for reliable auto operation and a built-in safety mechanism that can shut down connected HVAC equipment when high reservoir water is detected, reducing overflow risk. The compact, durable construction includes a removable 1/2 gallon reservoir and multiple inlet ports for easy integration with several devices. An integrated check valve on the outlet helps maintain efficient drainage.
Aquastrong 9.6 GPH Mini Split Condensate Pump
This compact pump is designed for mini-split systems and other HVAC configurations needing quiet operation with up to 9.6 GPH flow and a head up to 33 feet. A reliable hall switch supports automatic activation, and the safety switch wiring can terminate operation or trigger alarms in the event of overflow. Its slim form factor allows installation in tight spaces, such as line set covers or wall cassettes. The unit includes a removable reservoir and filtration for straightforward maintenance, plus compatible tubing and a compact footprint for unobtrusive placement.
Diversitech Ultracp-22 Ultra Series
Designed for broader HVAC/R workflows, the Diversitech Ultracp-22 provides a 22-foot maximum lift, enabling effective condensate removal from systems located higher than standard basements. The pump is built for standard condensate applications with a 120V motor, ensuring dependable operation across a wide range of temperatures. This model is suitable for larger installations or setups where vertical clearance requires a taller discharge path. The design emphasizes durability and compatibility with typical condensate lines in residential and light commercial environments.
Little Giant VCMA-15ULST 115V Condensate Pump
The Little Giant VCMA-15ULST features an automatic condensate removal design with a vertical switch, reducing footprint while ensuring reliable drainage from boilers, furnaces, and air conditioners. Its 1/50 HP motor delivers steady performance and is thermally protected, helping prevent overheating. The unit’s ABS and stainless steel components offer durability in harsh condensate environments, and it is rated for water temperatures up to 140°F. An overflow-detection approach helps protect equipment and spaces from spills, making it suitable for compact utility rooms or mounted installations.
Aquastrong 70 GPH Condensate Pump with Safety Switch
This Aquastrong unit provides a balanced 70 GPH flow with a vertical lift capacity to accommodate mid-range installation heights. It includes a safety switch option that can be wired to HVAC equipment or alarms to automatically shut down or alert in overflow scenarios. The design emphasizes ease of maintenance, with a removable reservoir and filter, plus a 3.3-foot power cord for flexible placement. It supports multiple devices through several inlet ports and uses a durable thermoplastic body that resists abrasion and corrosion.
Buying Guide: Key Considerations for In Line Condensate Pumps
- Flow rate and lift height: Match the pump’s maximum GPH and vertical lift to your system’s condensate volume and the height to discharge. Higher lifts may require more powerful models.
- Safety features: Look for automatic shutoff via float or safety switches, which prevent overflow and protect HVAC equipment and surroundings.
- Inlet/outlet compatibility: Ensure inlet ports, tubing sizes, and outlet connections align with your condensate lines and fittings. Some models offer multiple inlets for parallel connections.
- Installation flexibility: Consider compact or vertical designs for tight spaces, and check whether the unit is rated for the expected water temperature and chemical exposure.
- Maintenance needs: Removable reservoirs and accessible filters simplify cleaning and reduce clog risk. Plan for periodic inspection every few months.
- Power and noise: Check voltage requirements and damping features for quiet operation, especially for installations in living spaces or bedrooms.
- Applications: Choose a model optimized for central AC, furnace condensate, dehumidifiers, or mini-splits, as some pumps are engineered specifically for particular setups.
