Circ Pump, Watkins Silentflo 5002, (2-Speed)
Item #: 75073
OBSOLETE-DISCONTINUED BY THE FACTORY-Use the 74427
This two speed circulation pump was used on 1995-1996 Hot Spring Grandee, Highlife, 220v Sovereign (IH model), 220v. Classic (FH model), Landmark & Summit. Also used on the Tiger River Khyber, 220v. Manora (MH model) and the 220v Tondi (PH model). The second speed feature insured that the water flowing through the original 5500 Cartridge Style Heater would flow fast enough to prevent it from tripping the high limit sensor. Even though the above mentioned spa models were wired 220 volts this circulation pump is a 115 volts just like the spa light.

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.
Technical Specs: Minimum flow for the circulation pump is 1 gallon in 30 seconds for low speed and 1 gallon in 20 seconds on high speed.
