How do you size a heating circulating pump?

1 GPM = 10,000 BTU/hr, meaning that for every 10,000 BTU’s of heat load the circulator must output a 1 gallon per minute flow. Assuming that system calls for 100,000 BTU/hr, a circulator pump should have a minimum 10 Gallons Per Minute flow rate at a given pressure drop.

What do the numbers mean on a Grundfos pump?

Answer: The model numbers (or material numbers) as Grundfos refers to represent the inlet/outlet diameter and the head ability in metric. For example, the Magna 3 65-120 has a 50mm (1.96″) diameter and the head is 120 meters (36′ TDH).

How do I choose a circulating pump?

Flow rate: Calculate your desired flow rate by multiplying the total volume by the time in which you want to move the liquid. For example, for a 500-gallon pond that needs full circulation once an hour, you would want to select a pump with a minimum rated flow rate of 500 GPH (gallon per hour).

How do you size a hydraulic pump?

1 HP is required for each 1 GPM at 1500 PSI or any multiple of 1500 such as 3 GPM at 500 PSI, 2 GPM at 750 PSI, 1/2 GPM at 3000 PSI, etc. Another handy rule-of-thumb is that it takes about 5% of the pump maximum rated HP to drive the pump when unloaded and pressure is very low.

What size water pump do I need for my home?

Pumps are rated in GPM (gallons per minute). A typical 3- to 4-bedroom home requires 8-12 GPM. When determining your home water needs, add one GPM for every water fixture in your home.

What setting should a circulation pump be on?

Some pumps have adjustable speed and flow settings. The settings are usually between 1 and 3, with 1 being the slowest and 3 being the highest. If your radiators aren’t getting hot, the speed and flow may need adjusting.
