Portable Storage Pigs

Portable Storage Pigs are horizontal bulk storage containers ideal for large-scale, high-volume jobs that require a lot of cement. Their mobility allows them to be transported to various locations during the course of a project. Even better, storage pigs aren’t just for cement. They can hold a variety of materials including fly ash, frac sand, lime, barite, activated carbon, non-corrosive liquids, and soda ash.

Unloading a cement pig requires compressed air from an industrial-sized blower. If you are storing dry bulk material, you need a blower to access the material. Two blower options are available:

  • Diesel blower (Perkins or Kubota with fuel tank; Tuthill T850 blower, silencer, air filter with pre-cleaner, pressure relief valve, battery and cables; mounted to storage pig)
  • Electric blower (50 hp electric motor; starter package; 480 volt; Tuthill T850 blower, silencer, air filter with pre-cleaner, pressure relief valve; mounted to storage pig)

Blower transfer hose is available in 25′ to 100′ lengths with quick connects.
