Hydronic Circulating Pump for HVAC Systems

The Bell & Gossett PL-36 is a hydronic circulating pump designed for HVAC applications. It operates on 115V AC single-phase power with a 1/6 hp motor. The pump handles potable water systems and offers compatibility with multiple intake pipe sizes.

Upgrading from Smaller-Capacity Circulators

This model replaces older or undersized circulators when higher flow rates are required. The jump is worth it when systems demand up to 38 gpm at 1 foot of head or 34 gpm at 10 feet of head. It suits installations needing a standard single-speed pump with a 6 3/8 inch face-to-face dimension.

Steady Flow Under Continuous Operation

Under sustained load the pump delivers consistent performance across its head range. It maintains 30 gpm at 15 feet of head and reaches a maximum of 37 feet of head. The cast iron construction supports durability during continuous hydronic circulation duty.

The pump needs a 6 3/8 in face-to-face dimension between the flanges.

Which way must the arrow on the PL-36 casing point during installation?

The arrow must follow the system flow direction; reversing it is the common mistake.
