Hey there! As a supplier of submersible sewage pumps, I often get asked about various maintenance tasks, and one of the most common questions is how to check the oil level in a submersible sewage pump. Today, I'm gonna walk you through this process step by step.
First off, why is checking the oil level so important? Well, the oil in a submersible sewage pump serves multiple crucial functions. It lubricates the moving parts inside the pump, reducing friction and wear. This helps to extend the lifespan of the pump and keeps it running smoothly. Additionally, the oil acts as a coolant, dissipating heat generated during operation. And it also provides a seal to prevent water from entering the motor compartment, which could cause serious damage.
Before you start checking the oil level, you need to take some safety precautions. Make sure the pump is completely turned off and disconnected from the power source. This is super important to avoid any risk of electric shock. Also, wear appropriate protective gear like gloves and safety glasses, as the oil can be messy and might cause skin or eye irritation.
Now, let's get into the actual process of checking the oil level.
Step 1: Locate the Oil Plug
The first thing you gotta do is find the oil plug on the pump. Usually, it's located on the side or bottom of the pump housing. The exact location can vary depending on the make and model of your pump. Some pumps might have a small access panel that you need to remove to get to the oil plug. If you're having trouble finding it, refer to the pump's user manual. It'll have a diagram showing you exactly where the oil plug is.
Step 2: Prepare the Area
Once you've found the oil plug, it's a good idea to prepare the area around the pump. Place a clean, absorbent cloth or a drip pan underneath the oil plug to catch any oil that might spill out. This will make cleanup a lot easier and prevent the oil from making a mess on the floor or in the pump pit.

Step 3: Remove the Oil Plug
Using the appropriate tool (usually a wrench or a screwdriver, depending on the type of plug), carefully remove the oil plug. Be gentle and take your time to avoid stripping the threads. As you remove the plug, you might notice a little bit of oil starting to seep out. That's normal, but if a large amount of oil gushes out right away, it could be a sign of overfilling or a problem with the pump.
Step 4: Check the Oil Level
There are a few different ways to check the oil level. One common method is to use a dipstick. Some pumps come with a built - in dipstick attached to the oil plug. If yours does, simply insert the dipstick into the oil reservoir, then pull it out and check the oil level against the markings on the dipstick. The markings usually indicate the minimum and maximum oil levels. The oil level should be between these two marks.
If your pump doesn't have a dipstick, you can visually inspect the oil level. Look into the oil reservoir through the opening where the plug was. You should be able to see the oil level. If the oil is below the minimum level, it means you need to add more oil. If it's above the maximum level, you'll need to drain some oil out.
Step 5: Add or Drain Oil as Needed
If the oil level is low, you'll need to add the appropriate type of oil. Check the pump's user manual to find out what kind of oil is recommended. Different pumps might require different types of oil, so it's important to use the right one. You can use a funnel to pour the oil slowly into the reservoir until it reaches the correct level.
On the other hand, if the oil level is too high, you'll need to drain some oil out. You can do this by using a small siphon or by carefully tilting the pump (if it's safe to do so) to let the excess oil drain out through the opening. Keep checking the oil level as you drain to make sure you don't drain too much.
Step 6: Replace the Oil Plug
Once you've adjusted the oil level, it's time to put the oil plug back in. Make sure the plug is clean and free of any debris before you insert it. Tighten the plug securely, but don't over - tighten it, as this could damage the threads.
Step 7: Clean Up
After you're done checking and adjusting the oil level, clean up any spilled oil. Wipe down the pump housing and the area around it with the absorbent cloth. Dispose of the used oil properly according to local regulations.
Regularly checking the oil level in your submersible sewage pump is an important part of maintenance. It can help prevent costly repairs and keep your pump working efficiently for a long time.
