Kawasaki StaffaӔ high torque, low speed radial piston motors use hydrostatic balancing techniques to achieve high efficiency, combined with good breakout torque and smooth running capability.The HPC series dual displacement models have two pre-set displacements which can be chosen from a wide range to suit specific application requirements. The displacements are hydraulically selected by a directional control valve which can be remote mounted or directly on the motor. Motor displacement can be changed with ease when the motor is running.These motors are also available in a continuously...

Performance data is valid for the range of HPC motors when fully run-in and operating with mineral oil. The appropriate motor displacements can be selected using performance data shown on pages 4 to 8.

Consideration should be given to the required motor bearing life in terms of bearing service life. The factors that will determine bear life include: 1. Duty cycle - time spent on and off load 2. Speed 3. Differential pressure 4. Fluid viscosity, type, cleanliness and temperature 5. External radial shaft load 6. External axial shaft loadA heavy duty HP(HD)C motor can be ordered to further improve bearing life. Consult KPM for further details. >

To select either displacement, a pressure at least equal to 2/3 of the motor inlet/outlet pressure (whicheveris higher) is required. In most applications the motor inlet pressure will be used. If the inlet/outlet pressure is below 3.5 bar, a minimum control pressure of 3.5 bar is required. In the event of loss of control pressure the motor will shift to its highest displacement. > Refer to performance data, (see pages 3-8). > The minimum operating speed is determined by load inertia, drive elasticity, motor displacement and system internal leakage. If the application speed is below 3...

The flow rate of oil for the make-up system can be estimated from the crankcase leakage data (see pages 9) plus an allowance for changing displacement: e.g.HPC080 To change high to low in 0.25 sec requires 32 l.p.m. HPC125 To change high to low in 0.5 sec requires 15 l.p.m. HPC200 To change high to low in 0.5 sec requires 15 l.p.m. HPC270 To change high to low in 1 sec requires 24 l.p.m. HPC325 To change high to low in 1 sec requires 20 l.p.m.Allowances should be made for other systems losses and also for fair wear and tearӔ during the life of the motor, pump and system components. > The...

When operating the motor at low temperature consideration should be given to the fluid viscosity. The maximum fluid viscosity before the shaft should be turned is 2000 cSt. The maximum fluid viscosity before load is applied to the motor shaft is 150 cSt.If low ambient temperature conditions exist, then a crankcase flushing flow of 5 I/m should be applied to the motor during periods when the motor is not in use.The shaft seal temperature limits for both medium and high pressure applications are shown in the table below. All seals are very brittle at minus 40 > Non-operating temperature...

All Staffa motors can be used in freewheeling applications. In all circumstances it is essential that the motor is unloaded (A and B ports connected together) and that the circuit is boosted.The required boost pressure will be dependent on speed and displacement. It should be noted that for Bђ series motors large flows will re-circulate around the motor. This will require a large re-circulating valve and consideration of circuit cooling as the motor will generate a braking torque. It is for these reasons that Cђ series motors are the preferred option for freewheeling applications. It is...

Spigot Bolt torque The motor should be located by the mounting spigot on a flat, robust surface using correctly sized bolts. The diametrical clearance between the motor spigot and the mounting must not exceed 0.15mm. If the application incurs shock loading, frequent reversing or high speed running, then high tensile bolts should be used, including one fitted bolt. The recommended torque wrench setting for bolts is as follows: M18 312 +/_ 7 Nm 5/8 UNF 265 +/_ 14 Nm M20 407 +/_ 14 Nm 3/4Ԕ UNF 393 +/_ 14 Nm Shaft coupling Where the motor is solidly coupled to a shaft having independent...

The recommended minimum pipe size for drain line lengths up to approx. 5m is 12.0mm 1/2 bore. Longer drain lines should have their bore size increased to keep the crankcase pressure within limits. Specify ԓV within the model code for extra drain port, G1/4Ԕ > (BSPF) . Connect this port into the main drain line downstream of a 0.35 bar check valve to ensure good bearing lubrication. The piping arrangement must not allow syphoning from the motorcase. The piping, from any drain port, must be taken above the level of the motorcase to ensure good bearing lubrication. The arrangement must not...
