- Handles big solids: Can handle LOTS of solids and even big solids on oil skimming projects
- Solids advantage over typical 1″: Typical 1″ pumps pass only 1/8″–1/4″; these are built for real debris
- Rotatable connections: 180° inlet/outlet rotation to configure exactly how you need
- Service-friendly air side: Air side can be serviced without opening the wet (diaphragm) side
- Lube-free operation: Pumps operate LUBE FREE for simple maintenance
- Material options: Standard cast aluminum with Buna seals; cast iron or stainless available
- Stocked sizes: 1″ and 2″ on the shelf with matching suction/discharge hose kits
- High head capability: Heads up to 125 psi or 289 ft. of water
IN STOCK. READY TO SHIP. PROBLEM SOLVED.

WHY SKIMHAWG AOD PUMPS MATTER
Oil skimming projects always bring debris. These pumps move the solids other 1″ units choke on, run lube-free, and service easily—so the skimmers stay fed.
What They Are: Air Operated Diaphragm Pumps
Specifications
The beauty of our floating Big Ass Surface Skimmer is that it has only one moving part-the hinged weir and it can work with any pump that can pull suction. We’ve had the floating weir skimmers on the market for over 20 years, so they are a well proven and reliable surface skimmer that automatically self adjusts to the pumps flow rate-allowing the operator to take as little as 1/8” to over 3” of water off the surface—–without affecting the underlying water or in the case the underlying settled coal ash. We now have these floating weir skimmers working in several power plants dewatering ash ponds. Ironically several years ago several power plants were using the smaller FWS units to remove floating centospheres of ash from the surface of water in many similar ponds.
Like most everything else that we all used to do, we’ve found a better way to do it today. This is certainly true of coal fired power plants and their waste ash disposal and storage. Back when the power plants started using ponds for storing the ash under a water cap it was probably the recognized best method. Out of sight and out of mind. Somewhat.
