A-Frame Mini Dredge

The DAE Pumps A-Frame Mini Dredge is a full dredging system for the removal of silt, sediment, sludge, and sand from the bottom of lakes, ponds, lagoons, rivers, and canals. The A-Frame Mini Dredge is a manual pulley dredge for removing material and increase the depth of water levels. Dredging allows for boat access to docks and through low waterways and improves the beauty and size of small acre ponds and lakes. Our manual pulley dredge is a simple way to perform low-cost dredging.

At the center of the mini dredge system is the submersible slurry pump. The DAE Pumps submersible slurry pumps provide durable and reliable movement of the most abrasive material like sand and sediments. Made of high chrome metal, the DAE Pumps submersible slurry pumps are robust and capable of pumping high amounts of solids. The heavy-duty impeller, volute, and casing make our pumps durable and long-lasting.

Featured around the pump is the supporting A-Frame raft system that floats the submersible pump. The high-quality foam-filled raft provides the required support to keep the pump afloat at the desired depth for easy movement. In turn, the chain support allows for adjustment of height to lower and raise the submersible pump where needed.

In addition to the high-quality pump and raft, our pulley dredge kit provides everything you need for dredging. The dredge kit includes double braided nylon rope, heavy-duty stakes and pulleys, and high-strength chain and connection links. We also offer lay flat slurry hoses and floats. Get it all in one easy call and ask about our full package that includes straw wattle and stakes.

Selecting The Equipment to Pond Dredge

When selecting a submersible pump for dredging a pond, lake, lagoon, or other waterways, the pump should be capable of processing the material without clogging. A slurry pump made with high chrome metal casings and parts is ideal for moving sediment. They tend not to clog or wear like standard types of pumps can. Visit DAE Pumps Slurry Pumps for our large selection. If cleaning out muck and sludge with minimal sediment, use a DAE Pumps sludge pump. The sludge pumps are made of high chrome metals but wear parts are not as durable as the slurry pumps parts. See our sludge pump selection here!

Or choose from one of our pre-designed Mini Dredge Kits above!

An important aspect of the pump is the power cord. Most pumps come with 60-65 feet of 3-phase cord. To ensure the cord length meets your requirements, measure the widest section of the area. A skilled electrician will be able to connect and seal additional wiring that would be exposed to water if the cord is undersized. Also, if the cord is too small you can potentially run one-half the width and then run the other half. A DAE Pumps Representative can help you with the right length cord.

Fitting the pump with the right generator for power is essential. The generator must be able to power the pump at startup and consistently run without interruption. A DAE Pumps representative or local rental company can help you identify the right generator for the pump.

The lay-flat discharge hose should consist of synthetic woven liner reinforcement with a ribbed nitrile rubber cover or higher quality. This high-quality material helps protect the hose for less wear and tear as abrasive material passes through. 

DAE Pumps offer rafts for many of our submersible pumps. These rafts are designed to suspend the pump in water for dredging and dewatering. The raft is an integral part of the set-up for designing a pulley-style dredge. A properly sized raft must support the pump and offer chain length modifications.

Set Up The Catch

Setting up the dredge system catch is key to the dredging process. You want to pump out the sediment and murky water and replace it with clean water at the same time. After the pumping is complete, being able to remove the sediment is something to consider. 

The catch on a pond dredge system can be set up in a couple of ways: 

  • The cleanest and easiest catch is a dewatering bag. These bags fill up with sediment and water from the discharge and the water seeps out, thus collecting the sediment and muck. Using dewatering bags is pretty easy, but they can slow down your production time filling bags quickly and having to stop and replace them with another bag. Once the material is dried they offer easy removal. 
  • Another option is to build a multi-level drainage system not too far off the waterline so the water can flow back into the pond. Between each level add straw wattles and secure them with stakes. The straw wattles act as barriers and strainers. They hold back the sediment and filter the water so clean water fills back into the pond while pumping.
Dewatering Bag

Set Up The Pulley Dredge 

  1. Using the chain and clamps, connect the pump to the raft so the pump touches the bottom of the pond.
  2. Place an eyelet stake on each end of the pond on the shore. 
  3. Secure the eye pulley to the eyelet of each stake 
  4. Connect the rope to one eyelet of the raft 
  5. Run the free end of the rope thru the pulleys on each side of the pond 
  6. Connect the free end of the rope to the eyelet on the other end of the raft allowing for a little slack in the rope for movement
  7. Securely connect the discharge hose to the pump discharge nozzle 
  8. Attach several floats to the discharge hose and to the power cable so the lines are at the top of the water level and do not get caught up with the pump.
  9. Fix the discharge end of the hose to the dewatering bag or affix to a stake if using a multi-level drainage system. 
  10. Have a certified electrician connect the power cord to the generate and start the pump to be sure the electrical is working properly

Start Dredging 

Now that the pulley dredge is set up you can manually drag the dredge from one side of the pond to the other. As the pump moves over the bottom of the pond, it will suction the sediment and discharge it in the bag or drainage catch. You may need to adjust the discharge end of the hose to disperse the material exactly into the drainage system. Depending on the horsepower and intake of the pump, the pump will suction several inches to a couple of feet of material at a time. 

When the dredge reaches the other side of the pond move the stakes on both ends of the pond about a foot or so and pull the dredge back to the other side. Repeat this process until the entire pond has been dredged. Once complete, lower the pump on the chain and repeat dredging the pond until you reach the desired depth.
