Bell & Gossett RO-5 Read-Out Pump Balancing Kit

The Bell & Gossett RO-5 Read-Out Pump Balancing Kit (Model RO-5, part number 117020) provides direct differential-pressure readings to balance Bell & Gossett Circuit Setter Balance Valves, Circuit Sensor Flow Meters, and Triple Duty Valves across a multi-pump loop. Its floating-piston differential pressure gauge delivers a continual bleed across the surface, eliminating the need for separate vent valves, and the scale runs from 0 to 25 feet of water (0–0.7 kg/cm²) for straightforward in-situ measurements. The kit includes five-foot hoses, readout probes, a carrying case, and a circuit setter balance valve calculator, with maximum operating temperature up to 235°F and maximum pressure rating of 250 psig, enabling use in typical HVAC and hydronic piping systems. Designed for measuring differential pressure across components such as pumps, suction diffusers, strainers, and coils, it helps verify balance points and confirm that the network demand is met by the installed equipment, making it a practical tool for field balancing and commissioning.
