1-4 Special Features 1-4 Special Features Feature + High Pressure Shaft Seal Description: > 10 bar rated > Recommended for cold climates > Rugged steel and PTFE construction Technical Information Where crankcase pressure will be higher than 3.5 bar, the high pressure shaft seal should be selected. Case pressure Applicable to: • Available O Not available If a motor is to be ordered with any special features listed, please contact Kawasaki. Please contact Kawasaki to order this feature.

1-4 Special Features 1-4 Special Features + Improved Shaft Seal Life + Improved Cavitation Resistance Description: > Stainless steel sleeve prevents corrosion > Improved wear resistance > Recommended for corrosive environments Description: > Recommended for overunning applications > Protects against seal damage for short periods of operation in vacuum inlet conditions. Sleeve material Technical Information A well-established method of increasing rotary seal life in corrosive environments is to fit a thin-walled, stainless steel sleeve to the rotating shaft to provide a corrosion-resistant,...

1-4 Special Features +Anti-pooling Bolt Heads ^ Increased Starting Torque Description: > Removes potential for water pooling > Improved corrosion resistance > Recommended for marine environments Description: > Optimised for high break-out torque > Recommended for low speed operation > Improved service life for low speed applications Technical Information In many marine applications, water pooling in socket head cap screw heads presents a significant corrosion risk. Corroded cap screws can make service and repair of affected units impossible. To significantly reduce the risk of water damage...

1-4 Special Features + Increased Starting Torque (cont) Volumetric Performance In order to achieve increased torque at low speeds the volumetric characteristics of the motor performance are changed. When calculating leakage and volumetric efficiency use the constants shown here in place of those given for the standard motor on page 27. 1-4 Special Features +Anti-Clockwise Rotation Description: > Reduce installation complexity > Standardise equipment designs Motor Type Technical Information All HPC motors can be specified with an anti-clockwise rotation valve configuration. All performance...

Description: > Recommended for cold climates > Optimised for start-up in freezing temperatures > Engineered for total peace of mind Technical Information Starting up a cold system with warm hydraulic fluid is a known cause of heavy wear and potential seizure of hydraulic machinery. To minimise this potential risk, the HPC motor can be configured to combat thermal shocks to give complete peace of mind when operating in very cold climates. Applicable to: Motor Type Please contact Kawasaki to order this feature. Volumetric Performance In order to provide thermal shock resistance the volumetric...
