Description

KM Series
Our pumps are equipped with 13-tooth gears that have precision fixed clearances. Designed with hardened and ground sintered gears in high tensile strength housings.

How to Select Pump and DC Motor Combinations:

The following section contains pump/motor curves for various combinations of pumps and motors used on Stone hydraulic power units. It is important to select the correct motor and pump for a given application so proper pressure, flow and electrical amp draws can be accounted for appropriately in the design circuit. Proper selection also ensures the motor does not overheat and become inoperable.

There are motor curves for both S2 and S3 duty cycle categories.

S2- Absolute Continuous On-time. Indicates how long a motor can be run continuously before it must be allowed to cool back to ambient temperature.

S3- Percentage On-time. Based on a 5 minute duty cycle, it indicates the duty cycle (percent on vs percent off) the motor can be run continuously without overheating the motor.
