Bell & Gossett 168022 Series 1535 – 351T – 1/3HP Pump

Industrial process-cooling and commercial HVAC systems can consider the Bell & Gossett 168022 Series 1535 with 1/3 HP, 208 to 230 or 460 V three-phase power, close-coupled centrifugal construction, and a 1,725 to 1,750 RPM operating range.

The standard carbon, ceramic, and Buna-N mechanical seal provides a defined sealing arrangement for application review. The supplied record does not state exact flow, head, NPSH, pressure, temperature, or efficiency, so final selection requires the applicable Series 1535 curve.

Key Features

- The 1/3 HP motor establishes the listed power class for process-cooling planning.
- 208 to 230 or 460 V three-phase power supports electrical compatibility review.
- Close-coupled construction combines pump and motor within one equipment assembly.
- Operating speed between 1,725 and 1,750 RPM establishes the rotating reference.
- Carbon, ceramic, and Buna-N materials identify the standard mechanical seal.
- Series 1535 construction provides the product-family reference for technical documentation.
- Industrial process cooling and commercial HVAC define the listed applications.

Hydraulic Performance and Application

The Series 1535 is listed for three-phase industrial process cooling and commercial HVAC service. Exact flow, head, NPSH, pressure, temperature, pump curve, and efficiency values are not supplied for this 168022 configuration, so the 1/3 HP rating and operating speed cannot confirm hydraulic suitability.

Installation Requirements

Confirm three-phase voltage, close-coupled mounting, piping compatibility, rotation, seal material, fluid temperature, pressure, service clearance, and motor protection before commissioning. Three-phase equipment should include appropriate external protection, while the mechanical seal must match the approved fluid and operating conditions.

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. Mechanical-seal inspection remains relevant to service planning. Mulmotor provides pre-purchase support.
