**New model of 40PU2.15S**
The PU-series is a submersible vortex pump designed for raw sewage, wastewater, and liquid carrying solid matters. It is made of resin and 304 stainless steel and excellent in corrosion-resistance. The vortex mechanism provides practically unchokable operation in sewage pumping. Liquid paraffin is used for the lubricating oil, which widens the application of the pump to decorative waterfalls, fishponds, aquaculture, etc.
Features:
- Motor Protector Miniature Thermal Protector - Detects excess heat, therefore, protecting the pump against overheating and dry-running
- Dual Inside Mechanical Seals - Isolated in the oil chamber where a clean, non-corrosive and abrasion-free lubricating environment is maintained. Compared with the water-cooled outside mechanical seal, it reduces the risk of failure caused by dry-heating and adhering matter
- Liquid Paraffin Oil = Fish Friendly - This high-purity oil is commonly used in the cosmetics, pharmaceuticals and food processing equipment. Because it is a food grade lubricant, the pump can be safely used for water features in carp/koi ponds and fish farms.
- Resin Vortex Impeller - Resists wear caused by abrasive particles and enables the pump to maintain its original performance for an extended period of time.
- Corrosion-resistant
- Compact, lightweight and easy to handle
- 24/7 continuous duty operation
