Portable Variable-Frequency Permanent-Magnet Pump
Portable permanent-magnet pump
Overview
Portable Permanent-Magnet Pump
This portable pump uses a permanent-magnet synchronous motor and must operate with the matched variable-frequency drive.
A hose or flange quick connection supports mobile drainage setup after the duty point, power supply and connection arrangement have been confirmed.
Applications
- Mobile and emergency dewatering.
- Drainage in tunnels and culverts, basements and garages, and vehicle-mounted drainage arrangements.
Working principle
The matched variable-frequency drive supplies and controls the permanent-magnet synchronous motor, which drives the pump.
The drive is part of the operating system and must remain matched to the pump specification; the pump is not connected directly to AC 380 V.
Features
- Portable arrangement for mobile or emergency drainage.
- Hose or flange quick connection for site setup.
- Protection functions are provided only according to the selected control configuration.
Verified conditions
- Drive requirement
- Matched variable-frequency drive required
- Quick connection
- Hose or flange
- Protection functions
- According to the selected control configuration
Selection inputs
- Required flow and total head, including piping losses.
- Available power supply, expected duty and the matched drive specification.
- Hose or flange connection, cable length and site mobility requirement.
- Selected control configuration and required protection functions.
Verification before selection
Use only the matched variable-frequency drive. Do not bypass the drive for direct AC 380 V connection, and do not mix drives across pump specifications.
Frequently asked questions
Can this pump be connected directly to AC 380 V?
No. It must be operated through the matched variable-frequency drive for the selected pump specification.
Can one drive be moved between different pump specifications?
Do not mix drives across specifications. Confirm the matched pump and drive as one operating set.
Which protection functions are included?
Protection depends on the selected control configuration and must be confirmed for the supplied system.
