Meet the Coast Spas Extreme Line of Jet Pumps. From the Monster Flow 7HP pump to the Smart Flow pump, all are designed to push the maximum allowable pressure through to our specially designed Luxury Trillium Massage Jets. During your spa's filtration cycle, your jet pumps are activated to pull and push water through your hot tub filter. During the filtration cycle, our highly efficient pumps will run on an ultra low voltage ( for 5HP Super Flow Pumps) and at one third the RPM (3450 high / 1150 low). Programmable filtration cycles allow you to control when, and for how long, your jet pumps activate to purge your hot tub of debris. During the programmed filtration time, your hot tub pumps will consume about as much power as your backyard aquarium pump.
