Grundfos 99812354 Pump
The Grundfos 99812354 is a professional-grade hot water recirculation pump designed for high-efficiency domestic water systems. Engineered with a low-noise permanent magnet motor, this Comfort 10-16DT PM BU/LC model optimizes energy consumption between 5 and 8.5 watts while delivering a maximum flow of 2.2 GPM. It features an integrated digital timer and temperature control functionality, allowing contractors to program precise operation windows that eliminate unnecessary heat loss. The brass pump housing is drinking-water approved and corrosion-resistant, making it a reliable choice for residential systems with a dedicated return line. With a maximum head of 3.9 to 5.25 feet and 145 PSI pressure rating, this circulator handles fluid temperatures from 36°F to 203°F. The compact union mount design includes a built-in non-return valve and isolating valve, facilitating straightforward maintenance without needing to drain the entire loop. This high-efficiency ECM circulator is a direct solution for homeowners demanding instant hot water and reduced utility costs.
Key Benefits for Contractors and Homeowners
- High-Efficiency Performance: Utilizes an ECM permanent magnet motor to significantly reduce electrical draw compared to standard induction motors.
- Integrated Digital Timer: Provides customizable scheduling to ensure the recirculation pump only runs during peak usage hours.
- Advanced Protection: Features dry-running protection and impedance-protected electronics to prevent motor failure during commissioning or air-lock events.
- Simplified Maintenance: The easy-to-separate pump head and spherical rotor design allow for quick cleaning of lime deposits without removing the brass housing.
- System Versatility: Dual voltage capability (115-230V) and 1-1/4 inch NPSM union connections provide flexibility for various site requirements.
Common Questions about the Grundfos Comfort 10-16DT PM
Does this pump require a dedicated return line?
Yes, the Grundfos 99812354 is designed for systems with a dedicated return line to provide instant hot water at every fixture.
Can the timer be overridden for continuous use?
The digital controller allows for a 100% continuous operation mode, which is particularly useful during system commissioning or high-demand periods.
What fittings are required for installation?
This is a union mount pump; 1-1/4 inch NPSM unions (typically 1/2 inch or 3/4 inch NPT/Compression depending on your pipe) must be sourced separately to complete the installation.
