Rated pressure 42 MPa (420 bar) and maximum 50 MPa (500 bar) for all series; on the M7X the sum of the pressures at ports A and B must stay within 56 MPa. Nnom is the maximum speed at maximum displacement; Nmax applies for displacement below 0.6 qmax (M7V212: below 0.4 qmax) and only with internal cooling. Temperature from -20 to 115 °C at the drain and from -20 to 90 °C at the inlet. The catalogue specifies anti-wear mineral oil, normal viscosity 10–200 mm²/s and minimum cleanliness -/18/15 ISO 4406. For use outside the catalogue conditions the manufacturer asks to be consulted.

M7V series regulators

Two-position electric (T1 24 V, T2 12 V) or hydraulic (Y1 negative control, Y2 positive): switches between maximum and minimum displacement
Electric proportional (E1–E4, 24 V or 12 V, negative or positive control)
Hydraulic proportional (P1–P4, pilot pressure 2.5 or 1.0 MPa, negative or positive control)
Pressure-related control (H1–H3): without or with pressure increase, also with hydraulic remote control
Optional valves: pressure control (A1), two-position electric (B1 24 V, B2 12 V) or hydraulic (C1, C2)
With pressure control active, the motor stays at minimum displacement up to the set value, then displacement increases

Options and accessories

SAE J744 2-bolt or 4-bolt flange or ISO 3019-2 4-bolt; rear or side ports
Threads: ANSI ISO 11926 (UNF) or parallel ISO 228 with metric flange fixing
Splined shafts ANSI B92.1 or DIN 5480, depending on size
Speed and direction sensor (4.5–26 V DC, IP69K, AMP Superseal 1.5 connector): 71, 77, 87 or 97 pulses/rev depending on size
Counter balance valve for lifting, with inlet at port A or B
Internal cooling as standard (flushing of 1.8 l/min on M7V85/112 and 5.0 l/min on M7V160/212 at 2.5 MPa); version without cooling with Nmax limited to Nnom

Frequently asked questions

What is the difference between Kawasaki M7V, M7VC and M7X?

M7V is variable displacement in sizes 85, 112, 160 and 212. M7VC is the cartridge version, size 160 only, designed to be mounted inside the gearbox. M7X is fixed displacement in sizes 85, 112 and 160. All work at 420 bar rated and 500 bar maximum.

What displacements and pressures do these motors reach?

Maximum displacement ranges from 85 to 215 cm³/rev on the M7V (sizes 85–212) and is 90, 112 and 160 cm³/rev on the M7X. Rated pressure 420 bar (42 MPa), maximum 500 bar (50 MPa).

Which regulators are available on the M7V?

Electric or hydraulic two-position control, electric or hydraulic proportional control and pressure-related control, with optional pressure control and two-position switching valves. Minimum and maximum displacement are chosen in order from the catalogue combinations.

Can I use these motors in a winch?

The catalogue provides a counter balance valve for lifting. For safety, starting with minimum displacement control is not permitted on winches. Send us the application data: a technician will check the configuration with you.

I need to replace a motor of another brand: how do I proceed?

Send us the code or nameplate of the motor to replace. A technician compares displacement, pressure, flange, shaft, ports and regulator with the M7V, M7VC and M7X versions and tells you the solution. A technician will reply within 24 working hours.

Can't find the code you need?Send us the code of the Kawasaki M7V, M7VC or M7X motor, or the displacement, pressure and regulator data of the motor to replace: we will tell you the correct code and delivery times.
