Why Professionals Choose Bell & Gossett Series PD Pumps

When time is money, you need a pump that won’t let you down. Bell & Gossett PD circulator pumps are trusted by HVAC contractors and plumbers for their:

High Efficiency, Low Cost

The energy-efficient design keeps costs down, especially in systems requiring continuous operation. Contractors report up to a 15% reduction in energy usage compared to similar pumps.

Ease of Maintenance and Extended Lifespan

The oil-lubricated bearing assembly and mechanical seals are easily accessible for quick repairs, reducing downtime. It's also the reason these pumps can last years longer than standard options.

Consistent Flow and Pressure

The Series PD pumps are designed to optimize flow rates and head pressures, ensuring smooth performance even in the most demanding systems.

Wide Compatibility

Whether you’re working on closed loop hydronic systems or potable water lines, there’s a model to match your needs.

Eco-Friendly Operation

As part of a sustainable solution, these pumps reduce energy waste, contributing to lower carbon footprints and compliance with energy efficiency standards like LEED certifications.

Key Features That Set These Pumps Apart

1. Three-Piece Design for Easy Repairs

Each pump is built with a volute, impeller, and bearing assembly that are easy to access and service. This saves time on-site, especially during emergency repairs.

2. Reliable Motors

Equipped with Bell & Gossett motors ranging from 1/2 HP to 1-1/2 HP, these pumps deliver consistent performance. Models like the PD-37T run at 1750 RPM, ensuring steady flow and pressure.

3. Materials Built to Last

• Cast Iron: Ideal for hydronic heating and cooling in closed loop systems, this material ensures strength and durability.
• Bronze: Essential for pumping potable water, it offers long-term corrosion resistance in domestic water systems.

4. Energy Efficiency

With optimized impellers and oil-lubricated components, these pumps minimize energy waste. Systems using variable speed drives benefit even more as the pumps adjust to changing flow requirements.

Real-World Applications of Bell and Gossett Series PD Pumps

1. Residential Hydronic Heating

For homeowners relying on radiant heating or boiler systems, the Series PD pumps ensure consistent circulation. Their quiet operation and compact design make them a natural fit for these environments.

2. Commercial HVAC Systems

Take a large hotel as an example. Cooling systems rely on steady chilled water circulation, and downtime isn’t an option. The PD-40S, with its 1-1/2 HP motor, provides the high head pressure needed to keep the system running smoothly.

3. Industrial Applications

From manufacturing plants to hospitals, Series PD pumps handle high-pressure and high-flow systems. They’re commonly used in cooling towers, boiler feed systems, and processes requiring steady water circulation.
