Wichita Clutch I wcbAquaMaKKs Water Cooled Brakes

wcbAquaMaKKs Water Cooled Brakes

are designed to provide excellent controllability for drilling
feed off, tripping, pay out, and holding functions.

wcbAquaMaKKs brakes are air-applied, spring-released, water-cooled, friction interface brakes
designed ideally for draw-works, service rigs, dyno applications, and winches. Models are
available in 24” and 36” sizes.

Features:

• Interchangeable with existing ‘wcb’ types of brakes to allow for ease of installations,

wcbAquaMaKKs brakes are an air actuated water
cooled design, featuring copper wear plates
optimized for heavy-duty continuous slip tension
applications

conversions, and spare parts utilizations

• Units are available as either Air Tube Disc (atd) actuation, or as with true dual pistons (dpS)
actuation

• Reduced overall brake weight that is about 40% less than iron units

Oil and Gas

wcbAquaMaKKs brakes have superior water
cooled tension control and very high heat
dissipation to provide excellent controllability
on draw-works applications

Marine Deck Machinery

Positioning and mooring winches require high
heat dissipation and accurate tension control.
The performance and corrosion-resistant
features of the wcbAquaMaKKs brakes are
perfectly suited for these applications.

New engineered composite water jackets
improves performance

Wichita’s unique patented water jacket design, with improved
channeled water flow, ensures high heat absorption and torque stability,
providing greater heat dissipation compared to similar sized competitive
units. All water jackets are made of corrosion-resistant, lightweight
engineered composite material.

Corrosion resistant, saltwater friendly

Composite water jackets are not affected by use of hard, acidic water
that typically corrodes and plugs up cast iron jackets

Other composite water jacket benefits include:

• Improved channeled water flow – achieved via groove designed

and molded into jacket providing enhanced cooling capability

• Fast & easy maintenance created from the lightweight composite

jacket design that is about 60% less weight than the competitors
metal design

• Water jacket design and material allows for longer life, requiring

fewer replacements

• Water Jacket assemblies are interchangeable with WCB

compatible brakes

• For added protection, hardware used to attach copper onto the

composite water jackets is marine grade, fluoropolymer coated to
resist gauling and corrosion

(1,000 @ low pH [3.8] and 1,500 @ high pH [8.2] simulated for sea water)
