  • What’s the Difference: 2 Wire vs 3 Wire Submersible Well Pumps

    April 17, 2018

    Welcome back to another edition of Inspector Pumphead’s Quick Tips! In this space I, Inspector Pumphead, will be dispensing wisdom regarding your pump, whether it be about performance, maintenance, repair parts or navigating our site to find a new product, I’m here to help! This week we’ll be talking about the difference between 2 and 3 wire submersible well pumps. Firstly, both types feature a ground wire which shouldn’t be counted. Two wire pumps will have 2 black wires and a green wire. Three wire pumps have a black, red, yellow, and green wire. Let’s dive in and figure out which one is right for your application! The main difference between 2 wire and 3 wire well pumps is characterized by where the starting components for the motor are located. Three wire well pumps house the starting components (starting capacitors, running capacitors, relays, and thermal overloads) in a control box or panel. Control boxes are usually mounted on a wall above ground. Though the potential of failure for the parts is greater than a two wire system, the components can be easily accessed and cheaply repaired or replaced. For example, if a capacitor malfunctions on a three wire, just the capacitor itself will need to be replaced. Two wire well pumps do not use a control box. All the elements already come built within the motor or pump house itself. This allows for easier installation. However, if any of the starting components fail, the pump will have to be pulled up and the whole motor will have to be replaced. The likelihood of component failure in a two wire system is much lower than a three wire, although it is a much more expensive and time consuming endeavor if a part does fail. At the end of the day, it’s up to you to determine the more convenient approach for your application. Your circumstances may dictate one configuration over the other.  Keep in mind, motors that are more than 1.5 HP requires a three wire configuration and a control box to start the heavier motors. sales specialists are standing by to help you find the right pump or part, as well as to provide price quotes, stocking availability and shipping information.

  • Inspector Pumphead’s Video Classroom: Manual Pumps vs. Automatic Pumps

    September 28, 2017

    Welcome to Inspector Pumphead's video classroom! In this feature, I Inspector Pumphead will provide a video lecture on a subject related to pumps, parts and accessories. I hope you take good notes and pay close attention because we just might test you at the end! In this video lecture, my assistant Mike will talk about the difference between manual pumps and automatic pumps. My most attentive students will know that I've talked about this before! Watch the video or read below for further explanation. Manual vs. Automatic As the name suggests, manual cords operate when the power cords are plugged into an eletrical outlet. This grants the user control over the timing of an operation. This mode of operation is popular if you are on a job site or need to evacuate water temporarily (or if you're a control freak I guess). Manual pumps are often used in conjunction with a control panel as well. Automatic pumps use some kind of switch mechanism to activate the pump under certain conditions. The most popular kind is probably a tethered style float switch, which is attached by a cord to a pump and activates when the water level reaches a certain point. Watch the video for a cool animation example. Once you've watched the video, take the quiz below! If you complete the quiz, you'll get a coupon code for a $5 discount on any order of $30 or more!
