Tsurumi Submersible Sewage Pump – 50PU2.4S

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

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

The Tsurumi 50PU2.4S vortex pump for SG ponds and waterfalls

Tsurumi is a name we trust for hard-working submersibles, and this PU-series vortex pump shines where ordinary aquarium pumps choke. The recessed vortex impeller passes solids without clogging, so it copes with leaf litter and debris that collects in Singapore koi ponds, decorative waterfalls and holding vats. The resin and 304 stainless construction stands up to constant immersion, and the built-in thermal protector guards against overheating and dry-running if the water level drops.

For outdoor ponds here, plan around our weather. Monsoon downpours can overflow a feature and wash debris in, so position the pump where it stays submerged and protect the supply with an RCD. Brief power outages are common, so for stocked koi a backup aeration plan matters more than the pump itself. Flush the strainer periodically, as warm water and organic load mean gunk builds up faster than in temperate climates.
