Sikorsky S61 Auxiliary Hydraulic System
High performance and dependability are the trademarks of all Kawak Auxiliary Hydraulic Systems. The Kawak S-61 Auxiliary Hydraulic System out powers any other system available providing a versatile power source for operating attached or suspended implements used in agricultural, forestry and the firefighting industry, resulting in dramatic improvement of the productivity of the aircraft. When coupled with our hydraulic hover pumps refill rates of 2000gpm+ can be achieved, increased overall in fire system reliability, and the ability to win, meet, and keep fire contracts. This system like many Kawak Products was designed with direct input of S-61 operators to meet their requirements for an auxiliary power source.
