Pump motors are commonly used in irrigation, pool and spa, pressure washer, and water pumping systems to move liquids. Car wash motors are totally enclosed for protection in wet and humid environments where frequent washdowns occur. Carbonator pump motors are suitable for use in liquid transfer pumps, vending machine pumps, and other hub-mounted pumps. Close-coupled pump motors take up less space than frame-mounted pump motors and are often used in centrifugal pump applications. Fire pump motors are used to power pumps in fire sprinkler systems. Jet pump motors and deep well submersible pump motors pump water from a well or draw water up from groundwater sources. Oil well pump motors provide high-slip and high-starting torque required by heavy oil-drilling operations. Pool and spa pump motors circulate and filter water to help keep swimming pools clean. Pressure washer motors resist corrosion and can be used in applications where the pump is moving hot or cold water at high pressures.
