Bell & Gossett 6050B7016 Autocirc Ecocirc B 23-5 ACT Pump

Under-sink hot-water circulation can use the Bell & Gossett 6050B7016 Autocirc ecocirc B 23-5 ACT, featuring a 60 W ECM spherical motor, 115 V power, lead-free brass, and integrated thermostat and timer control.

This configuration serves potable hot-water systems without requiring a dedicated recirculation return line. Its documented operating limits include 145 psi maximum working pressure, 203°F maximum fluid temperature, automatic overload protection, and temperature-based activation between approximately 89.6°F and 95°F.

Technical Specifications

- A 60 W ECM motor identifies the electronically commutated drive for low-input circulation applications.
- 115 V, 60 Hz, single-phase power supports standard under-sink electrical planning.
- Lead-free brass construction provides the documented pump-body material for potable-water service.
- Type 316 stainless steel wetted components support material review for water-contact applications.
- An integrated thermostat and timer provide documented control functions for scheduled circulation.
- Automatic overload protection supports the stated motor-control configuration during operation.
- The 145 psi pressure limit establishes a documented boundary for system compatibility review.

Hydraulic Performance and Application

The ecocirc B 23-5 ACT is listed for potable hot-water recirculation without a dedicated return line, including retrofit installations and tankless water-heater systems. Its ECM designation supports the documented efficiency classification, while the available record does not provide a fixed flow guarantee or exact duty-point efficiency.

Installation Requirements

Verify 115 V, 60 Hz, single-phase power, potable-water compatibility, maximum pressure of 145 psi, fluid temperature between 50°F and 203°F, thermostat placement, timer settings, and under-sink clearance before startup. The installation must accommodate the supplied control arrangement and intended no-return-line configuration.

Warranty and Maintenance

Bell & Gossett provides an 18-Month Limited Warranty from shipment or a 1-Year Limited Warranty from installation, whichever occurs first, covering defects in materials and workmanship. Proper installation and intended use are required, while misuse, alteration, negligence, and contrary operation are excluded. The shaftless, sealless construction limits conventional seal-service requirements. Mulmotor can assist with product details.
