By using more than one Taco pump, you can add the heads together. Taco 009 pumps have up to 35 feet of head at .5 gallons per minute, and less feet of head when you need higher gallon per minute flow (for example, 11 GPM at 1 feet of head and 5 GPM at 20 feet of head). If you need more feet of head with a high GPM, you can combine pumps. By using 2 009-F5 pumps with 5 GPM, you will get 20 ft + 20 ft, or 40 total feet of head.
