![Standard of the seal-less pumps Medium-sized standard centrifugal pumps[ML for low temperature liquids]](../../imgs/p_ML_l.jpg)
The type MP, which is positioned as the core model of MAGPAC® series realize significant reduction in the total cost (life cycle cost) in addition to their three outstanding features, seal-less, high reliability and maintenance-free.
Covers a wide performance range up to 7.5kW and used in a variety applications.
These pumps offer the same high efficiency as mechanical seal pumps. Super-lubricating and super-low wear SiC-D bearings support the magnet drive securely thus result in maintenance free. In addition, they can transfer high temperature (MH) and low temperature (ML) liquid. Select the pump model that matches your requirements. All the three models (MP, MH, ML) can transfer liquid below freezing.
- Nitrogen purge port is provided to prevent moisture from freezing in the frame adapter.
- Nd magnets and low temperature gasket material are used in these pumps.
