Data sheet | APM 0.8 – 2.9 motors
1. Introduction
APM motors are designed for energy recovery
systems together with an APP hydraulic pump
and a double shaft motor. APM motors convert
hydraulic energy (pressure, ow) to mechanical
energy (torque, speed).
This data sheet is valid for APM hydraulic motors.
APM hydraulic motors are build to operate on
salt water and are based on the axial piston
principle with xed displacement, enabling a
very light and compact design. Lubrication of the
moving parts is provided by the salt water itself.
Shaft speed is proportional to the input ow.
The APM motor is not self-starting but needs a
rotational force to start turning.
Below a sectional drawing as an example of an
APM motor
2. Benets
• Constant torque over a wide speed range
• Compact design
• Easy to install
• Long life under severe operating conditions
• Few wear parts and low maintenance costs
• No oil lubrication
• Non-corroding materials
• Made for RO applications
