The 4 GG/6GF-6GX/TR8/TR10/TR12 series is a submersible asynchronous electric motor manufactured by Dab Water Technology. The first type the 4GG has 4 asynchronous two-poles submersible motor that requires 220 - 230 V. The 6GF-6GX has submersible asynchronous 6 two-pole motor made of 304 stainless steel and cast iron with electrophoresic surface treatment for parts that will have water contact. The TR8 has a rewindable 8 asynchronous two-poles or four-poles submersible motor that is house in a AISI 316 stainless steel and is supported by an iron casting while the TR10 has rewindable 10 asynchronous two-poles or four-poles submersible motor. The TR12 in another hand has 12 asynchronous two-poles or four-poles submersible. This series needs a mixture composed of water and glycol for cooling and lubrication of the thrust bearing assembly and carbon bushes.
