■ General Descriptions The HMF series three-speed models have three pre-set displacements which can be chosen from a wide range to suit specific application requirements. The displacement are hydraulically selected using remotely mounted directional control valves. Motor displacement can be changed with ease while the motor is running. 3 displacement modes Freewheel options available High torque at low speed Smooth running The range of three speed motors extends from the HMF100 in 1,524 cc/rev to the HMF325 in 5,326 cc/rev. There are four frame sizes as shown in the table below: Wide range...

1-4 Special Features The HMF motor can be ordered with special features which can improve the motor's performance for different applications. Further details about each feature are given on pages 8-21. Description: > 10 bar rated > Recommended for cold climates > Rugged aluminium construction Where crankcase pressure will be higher than 3.5 bar, the high pressure shaft seal should be selected. Please contact Kawasaki to order this feature.

HMF Series - 9

1-4 Special Features+ Improved Shaft Seal Life Description: > Stainless steel sleeve prevents corrosion > Improved wear resistance > Recommended for corrosive environments 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, wear-resistant counterface surface for the seal to run against. All HMF motors can be fitted with such sleeves upon request. Please contact Kawasaki to order this feature.

HMF Series - 10

1-4 Special Features+ Improved Cavitation Resistance Description: > Recommended for overunning applications > Protects against seal damage for short periods of operation in vacuum inlet conditions. Cavitation can occur due to many different factors. Although it is not possible to make the HMF motor resistant to cavitation, certain features can be added to improve the motor's resistance to short periods of lost port pressure. In applications where the HMF motor can be driven (like a pump) a risk arises that insufficient fluid will be provided to maintain a positive pressure at both main...

HMF Series - 11

Description: > Removes potential for water pooling > Improved corrosion resistance > Recommended for marine environments 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 through pooling, HMF motors can be supplied with silicone filler in all the bolt heads. Please contact Kawasaki to order this feature.

1-4 Special Features Increased Starting Torque Description: > Optimised for high break-out torque > Recommended for low speed operation > Improved service life for low speed applications Technical Information If an application demands the drive motor be run at speeds of less than 10 rpm for most of the duty cycle, or involves frequent start/stop or forward/reverse operation, the Staffa HMF motor range has it covered. All figures given in Section 2-1 Performance Data are still valid when selecting this feature. By optimising the HMF motor’s design for low speeds, it is possible to increase...

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 28. Please contact Kawasaki to order this feature.

1-4 Special Features +Anti-Clockwise Rotation Description: > Reduce installation complexity > Standardise equipment designs All HMF motors can be specified with an anti-clockwise rotation valve configuration. All performance and volumetric characteristics remain unchanged. Please contact Kawasaki to order this feature.

HMF Series - 15

1-4 Special Features Thermal Shock Resistance Description: > Recommended for cold climates > Optimised for start-up in freezing temperatures > Engineered for total peace of mind Technical Information Starting up a cold motor with warm hydraulic fluid is a known cause of heavy wear and potential seizure of hydraulic machinery. To minimise this potential risk, the HMF motor can be configured to combat thermal shocks to give complete peace of mind when operating in very cold climates. Volumetric Performance In order to provide thermal shock resistance the volumetric characteristics of the...
