Waterous Priming Pump Solenoid

Replacement kit for 12 volt priming pump motor solenoid. Kit includes solenoid, band clamp, and instructions.

A Waterous Priming Pump Solenoid is an electrical component that controls the operation of the priming pump on a Waterous fire pump. The priming pump is used to create a vacuum within the pump’s impeller housing, which allows water to be drawn into the pump and prepare it for operation.

The priming pump solenoid is responsible for activating the priming pump by opening a valve that allows air to flow into the priming pump chamber. When the solenoid is energized, it opens the valve, which allows air to flow into the priming pump and create a vacuum. This vacuum draws water into the pump, priming it for operation.

Once the priming pump has created a vacuum and water has been drawn into the pump, the solenoid is de-energized, which closes the valve and stops the flow of air into the priming pump. The fire pump can then be started and the primed water can be pumped out.

The Waterous Priming Pump Solenoid is an essential component of a Waterous fire pump, and is designed to ensure that the pump is properly primed and ready for operation. By controlling the operation of the priming pump, the solenoid helps to ensure that the fire pump operates safely and efficiently, and is able to deliver the necessary water flow and pressure to extinguish fires.

Replacing a Waterous Priming Pump Solenoid involves several steps, and should only be attempted by a qualified technician with experience in working with electrical components. Here is a general overview of the process:

  1. Turn off power to the fire pump: Before beginning any work on the priming pump solenoid, make sure that the power to the fire pump has been turned off, and that the system is isolated from any power source.
  2. Locate the priming pump solenoid: The priming pump solenoid is typically located near the priming pump, and may be connected to the pump by a small hose.
  3. Disconnect the wiring: Use a screwdriver or pliers to remove the wiring connections from the solenoid. Make note of where the wires are connected, so that you can reconnect them correctly later.
  4. Remove the old solenoid: Use a wrench or pliers to remove the solenoid from the mounting bracket or housing. Be careful not to damage any surrounding components.
  5. Install the new solenoid: Attach the new solenoid to the mounting bracket or housing, and tighten it securely. Be sure to use the correct mounting hardware and torque settings.
  6. Reconnect the wiring: Reattach the wiring connections to the new solenoid, making sure to connect them correctly based on your notes from step 3.
  7. Test the priming pump: Turn the power back on to the fire pump, and test the priming pump to ensure that it is operating correctly.
