What is a Sump Pump component?
  • Sump pump components may include motor, float, switch, volute, impeller, protection screen, cord, discharge port.
    • Motor types are single pole, split phase.
    • Float types are tether, vertical (mechanical or magnetic).
    • Switch types are diaphragm, float-switch, controllers (microprocessor, digital level)
    • Volute is the chamber in which impeller rotates
    • Impeller rotates and pushes the water out.  Its source of power is the motor.
    • Protection screens may be used to prevent small debris from collecting in the volute or obstructing the impeller.
    • Cords are plugged into electrical current.  Piggyback switch cords are extremely valuable. The main cord is plugged directly into the electrical current; it is for the float-switch operation; the cord that plugs into the piggyback operates the motor. If the float-switch fails the motor cord can be plugged directly into the electrical current and controlled manually. 
    • Discharge ports are connected to a pipe (PVC or garden hose) through which the water is pumped.


What is Sump Pump construction material used for components of a sump pump?
  • Motor housing are generally thermoplastic, cast iron, stainless steel or cast bronze.
  • Cast iron and bronze have longest life span.
  • Volutes are generally thermoplastic or cast iron. 
  • Impellers are generally thermoplastic or cast iron.
