Laars Heating Systems 2400-005 Pump

Laars Heating Systems 2400-005 Pump

The Laars Heating Systems 2400-005 Pump is a high-performance 115v circulating pump engineered specifically for closed-loop hydronic heating applications. Built with a rugged cast iron pump body and 1/25 HP motor, this unit serves as the primary circulator pump for boilers, radiant floor heating, and fan coils. It is a direct fit for Laars boiler parts catalogs and acts as a reliable replacement for the Grundfos UP15-42F model. With a maximum flow rate of 17 GPM and a max head of 15 feet, it ensures consistent thermal distribution across residential and light commercial zones.

Designed for professional-grade reliability, the hydronic circulator features built-in motor protection and stainless steel internal components to resist corrosion in closed loop heating systems. The flanged connection design simplifies installation and maintenance for field technicians. Operating at a quiet decibel level, it maintains system pressure up to 145 PSI while handling fluid temperatures from 36°F to 230°F, making it a versatile HVAC replacement part for diverse mechanical room configurations.

Key Benefits
  • Broad Compatibility: Seamlessly integrates with Laars Heating Systems and serves as a high-efficiency alternative to the Grundfos UP15-42F.
  • Durable Construction: Heavy-duty cast iron housing and stainless steel internals provide long-term resistance against wear and corrosion.
  • Optimized Performance: Delivering up to 17 GPM, this pump ensures uniform heat distribution in radiant and baseboard radiant systems.
  • Technician-Friendly Design: The flanged x flanged connection allows for rapid drop-in replacement, reducing downtime during emergency service calls.
  • Quiet Operation: Engineered for sound-sensitive environments, providing reliable circulation without mechanical vibration noise.
Common Questions

Is this pump compatible with solar heating or open-loop systems?

The 2400-005 is specifically designed for closed-loop hydronic systems. While its cast iron body is ideal for heating loops, it should not be used in open-loop potable water systems where oxygen-rich water could lead to premature oxidation.

What should I check if the pump is running but not moving water?

Verify that there is no air trapped in the lines, as airlocks are a common cause of flow failure. Also, inspect the impeller for debris or blockages that may be obstructing the 1/25 HP motor's torque.

How do I confirm if my existing flanges will work with this unit?

This unit features a standard flanged connection. To ensure a leak-free seal, always use the included Gaskets (O-rings) and torque the bolts evenly according to standard hydronic piping practices.
