Finding the right submersible pump isn’t always easy. If you’re dealing with high temperature liquids, you may experience the frustration of a premature pump failure. Let’s review possible causes.
But first, here are the basics. A submersible pump’s electric motor generates heat that if not dissipated properly can damage the pump. In most applications, the cooler pumped liquid transfers heat away from the motor to maintain the pump within safe operating parameters.
Pumping High Temperature LiquidsPumping liquids that are hotter than room temperature with a regular submersible pump (or a “high temperature” pump that doesn’t have a high enough temperature rating) can cause a series of issues that may result in catastrophic pump failure, including the following scenario:
High Endurance for Corrosion ProtectionAnother factor in selecting the right pump is understanding the impact of pumping corrosive materials. For example, in many food and beverage applications, frequent washdowns include corrosive cleaning agents that change the pH of the pumped liquid. Stainless steel pumps are an effective solution for corrosive materials. However, stainless steel pumps dissipate heat at ~1/7th the rate of cast iron pumps. This may again lead to motor overheating and eventually pump failure.
The One Key Question You Need to AskDo you have a pump that meets your application needs? Many pump providers claim to offer high temperature pumps, but you need to ask the specific temperature and duty cycle for which their pumps are rated. High temperature/high endurance pump design offers a reliable solution to one of the most common submersible pump failure modes. BJM Pumps uses a proprietary manufacturing process to offer high temperature, high endurance pumps that are rated for continuous duty at temperatures up to 200 degrees F, including stainless steel corrosion resistant pump options.
