About WILO EMU Motors

Wilo EMU pumps are equipped with proprietary motor designs that provide the optimum in performance and a low cost-of-ownership.

	Oil-Filled Motor Chamber Design FO/FK type motors feature an oil-filled motor chamber. The internal oil circulation cooling system of FO/FK motors effectively dissipate the waste heat produced by the motor by transferring it to the pumped liquid. more »
	Sealed Glycol Cooled Motor Design HC type motors feature a dry motor chamber, which is cooled by a hermetically sealed—and water/glycol-filled—cooling system. These motors are sometimes referred to as “jacketed”. The motor’s waste heat is dissipated by way of a labyrinth, high-efficiency, heat exchanger. more »
	Air-Filled Motor With Internal Glycol Circulation FKT type motors are isolated (jacketed) in an air-filled chamber. Waste heat is dissipated to the pumped liquid via a heat exchanger acting on an glycol-filled internal chamber. more »
	Air-Filled Motor Design Air-filled T type motors are cooled when submerged in the surrounding pumped liquid. The motor waste heat is emitted directly via the casing, to the pumped liquid. more »
Special WILO EMU Motor Design Features
	Thermo-Centric™ Engineering All Wilo EMU motors are engineered in a specific manner to effectively transfer heat away from the motor and thus ensure long-life operation in even the harshest conditions.
	Large Diameter Shafts Large diameter shafts are integral to all Wilo EMU pump motor designs and incorporate a minimum length to diameter ratio. For example, the typical Wilo EMU pump shaft is 3.126 inches in diameter.
	Enclosed Block Seals The proprietary enclosed block seal used on Wilo EMU pumps in conjunction with Wilo EMU motors minimize shaft length, which dramatically decreases the potential for shaft deflection. These seals incorporate silicon carbide sealing surfaces, which last 2-1/2 to 3 times longer than tungsten carbide seals.
