Tiger River Spa Silent Flo 5000 Circulation Pump E-5 


This SilentFlo E5 circ pump replaces all previous versions of single speed circulation pumps.

The new E5 replaces the SilentFlo® 5000 and all previous style single speed circulation pumps on all Hot Spring and Tiger River spa models from 1986 to 2009. The E5 was introduced in March of 2008 as the premier upgrade/replacement circulation pump.  The compact size and flexible positioning (can mount vertically on the sidewall of the equipment compartment) has won it favor with Hot Spring dealers worldwide. This little jewel uses less electricity and moves more water per minute than its predecessor, the Silentflo 5000. When you refill your spa and power it up this "next generation" magnetic drive slowly ramps up to insure that it's well primed with water. The position of the suction/inlet is 1-11/16" from the floor which is the same as the Silentflo 5000. The return/discharge is 4-1/4" off the floor same as the Silentflo 5000. This flexible pump can also mount on its side without the need to secure it to the floor of the equipment compartment with the attached bracket. The impeller is accessible simply by unscrewing the top ring of the pump. The circulation pump draws water through the circulation pump filter (1989 forward spas) and then pushes it through the heater, ozone injector (if equipped) and back into the spa through the heater return fitting or floor drain. It circulates twenty percent more gallons per minute than the Silentflo 5000 yet uses nearly half the wattage. Impressive!

Note: These circulation pumps are water lubricated and cooled and require the presence of water at all times. These pumps should NOT be operated without water present in the spa. If a "dry run" occurs , the pump has an internal safety device (thermal cut-off) that will automatically shut it down should it overheat. To reset this pump simply power down the spa for 10 seconds then power it back up.
