If you’re in the tunnel boring business, is there any worse feeling than hitting an unexpected underground water pocket? You don’t know how big of a pocket it is or what the inflow of water may be. Luckily, with today’s technology you’re able to analyze and probe into the area you’ll be drilling. You usually have a pretty good idea of what you’re going to run into. You’re able to plan in advance. That means you’re better prepared to select the right submersible pump you’ll need for the tunnel boring dewatering job. This post will help you understand what you need to consider to ensure you’ve got the pump to keep your project running even.Types of Tunneling
There are several types of tunneling, and each may require a different type of pump.
The quick assumption when it comes to high temperature pumps is that they’re only meant for high temperature liquids (up to 200°F, in BJM’s case). That’s not always the case. There’s a reason that BJM refers to its Fahrenheit pump as a high temperature AND high endurance submersible pump. The “high endurance” part comes into play when the motor produces its own heat that the pump needs to dissipate that has nothing to do with the temperature of the fluid.Diagnosing the Issue
Figuring out that you need a high temperature submersible pump for endurance issues isn’t always easy. There are indications that may point you (or your pump supplier) in that direction.
- Water Temperature Isn’t Hot Enough to Cause Issues: You are experiencing premature failures similar to when pumping hot liquid and the pump can’t dissipate the heat.
In the mining and aggregate industry, you face many complex challenges. From fluctuating demand to stricter regulations, you’re likely feeling more pressure to be more efficient than ever. One aspect that can have a big effect on your bottom line is using the right submersible slurry pump.
If you’ve experienced pump issues on past projects, then you know the impact it had on the project. Clogs, motor failures, and premature wearing are some of the problems that cause costly project downtime. The maintenance costs of pulling the pumps for repair and replacement quickly add up.Submersible Slurry Pump Selection Considerations
Mining and aggregate environments are especially tough on most pumps. Selecting the right submersible slurry pump is more important than ever to minimize your costs.
