The LPA® pump is a semi-hermetically sealed unit with important design features:

The impeller floats in a revolving magnetic field and is the only moving part.

The magnetic flux is supplied by an external motor with a magnetic coupling device. Because the motor is external to the system, a burnout cannot contaminate the system.

The external placement of the motor eliminates any additional heat back into the system.

In the unlikely event of motor failure, the motor can be replaced without the need to shut the system off or remove the refrigerant.

No need for variable drive or frequency control as the characteristics of all LPA® ‘s are self unloading which means less power consumed and less cost.

Mechanical life exceeds 20 years of reliable and stable operation.
