Water-cooled clutches and brakes for heavy duty tensioning

5th February 2013


The new AquaMaKKs range of water-cooled clutches and brakes from Wichita Clutch are for heavy duty continuous slip tensioning applications, for use in demanding sectors such as mining.

The AquaMaKKs are air, hydraulic or spring-set actuated units, integrating non-metallic composite water jackets and superior heat-dissipating copper wear plates that are optimised for heavy-duty continuous slip tension applications. Available in sizes (friction lining O.D.) from 482mm (19-in) to 914mm (36-in), the units provide up to 2535kW (3,400HP) of heat absorption, which is 35 per cent higher than the most robust units previously constructed for heavy-duty applications.

Designed with a series of alternating friction discs and water jackets, AquaMaKKs generates torque by applying axial force from the pneumatic, hydraulic, or spring-set actuator, which provides accurate torque control for constant tensioning. The design features fewer parts for simple installation and maintenance, and a shim design that makes it easy to maintain and adjust for wear. These features make AquaMaKKs a perfect solution for field retrofits, rebuilds or new OEM applications, especially as adjustment for wear is easily accomplished by removing shims without any unit disassembly.

The robust AquaMaKKs units are built with premium materials and finishes, with built-in corrosion protection ideal for marine and other harsh environments. Water jackets are made from composite materials, so no optional salt water corrosion protection is required. In addition, the patented water jacket design ensures industry-leading high heat absorption and torque stability, allowing for greater heat dissipation over similar sized units.

As well as setting the benchmark for operational performance, AquaMaKKs offers users the benefits of a unique mounting arrangement. This enables direct replacement to Wichita or competitors’ units, whilst requiring no design changes on the customer’s behalf.

Complementing the operation of the AquaMaKKs clutches and brakes, Wichita is offering the provision for electronic wear monitoring as an aid to preventative maintenance. In addition, the company is offering the option of its HICO friction material, which provides up to 50 per cent higher torque on the clutch and brake units. Further options include custom-engineered solutions for adding accessories, such as deck mount assemblies, water connection kits, shaft assemblies or covers.
