TR8 is a rewindable asynchronous 8 inch submersible motor. Designed for pressurization, lifting water from wells and water use in agricultural irrigation systems. Jacket in AISI 316 stainless steel. Rewindable stator available with PE2+PA windings that allow the use of the motor in special applications and/or with variable frequency drive. Cooling and lubrication through a mixture of water and glycol. Combined with the hydraulic part, it can draw water from at least 8" tanks, cisterns, or wells. Available as two or four pole only in a three-phase version also predisposed for the installation of the PT100 or PTC temperature sensor. Versions with direct start or star-delta starter. Motor available as TR8N in AISI 316 stainless steel and version TR8R in AISI 904 stainless steel. To be coupled with an hydraulic part.
