In building services, especially for pumps for heating and air-conditioning technology, the classification of the pump design according to the sealing (wetting of the motor) is widespread:
| Design | Description |
| Glandless Pump | Glandless pump with canned rotor motor |
| Glanded Pump | Centrifugal pump with shaft seal |
In addition, the subdivision according to the type of installation or the arrangement of the drive is common:
- Monobloc with flange-mounted motor
- DIN-standards with motor and coupling on common baseplate
