Data sheet | APM 0.8 – 2.9 motors

1. Introduction	APM motors are designed for energy recovery	The APM motor is not self-starting but needs a
	systems together with an APP hydraulic pump	rotational force to start turning.
	and a double shaft motor. APM motors convert
	hydraulic energy (pressure, flow) to mechanical
	energy (torque, speed).	Below a sectional drawing as an example of an
		APM motor
	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 fixed 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 flow.

2. Benefits	•	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
