Compliance and Restrictions



Stainless Steel Centrifugal Pumps are designed for continuous duty and are intended for use with clear, non-abrasive and nonflammable liquids compatible with the pump material make-up. These pumps are a non-self priming, gravity feed design; they will pull water a maximum of 15 ft. with the pump and suction line completely filled with water and a foot valve on the end of the suction line. Pumps operate with a 3450RPM motor. Single phase pump motors have thermal protection; it automatically shuts off with sudden rises in temperature and restarts after cooling down. All models are manual mode and require field wiring, no controls are supplied. Check motor wiring before putting units into operation (see motor nameplate for specific wiring diagram)
