Aussie Puddle Sucker
Model: LSC Pump
Australian Pump has just released a new lightweight submersible single phase residue dewatering pump. The Aussie LSC residue pump, dubbed the ‘Puddle Sucker’, is manufactured by Tsurumi Pump.
The world’s leading electro-submersible pump company, Tsurumi is based in Kyoto, Japan, where they have the capacity to build up to one million units per year.
The ‘Puddle Sucker’ is designed to remove water down to 1mm. Weighing only 12 kilos, it can be easily lowered into flooded sumps. The LSC is able to produce flows of up to 170 litres per minute, with a head of up to 11 metres.
“The Puddle Sucker is ideal for draining water from flat surfaces or removing water from flooded areas like cellars, basements, car parks or man holes” said Aussie Pumps’ Jeremy Murray. “It is a tough, reliable, hard working submersible which has all the qualities of the bigger Tsurumi pumps” he said.
The pump features a single phase 0.48kW, capacitor start electric motor and a 10 metre heavy duty submersible cable. A non-return valve stops any water from flowing back to the drained area unlike traditional centrifugal pumps. A resilient rubber base plate offers protection to the pump and stops the floor from being damaged.
The motor features an inbuilt thermal motor protection device that reacts to the heat generated by an over current or dry run conditions. This not only cuts off the motor circuit automatically, but also resets by itself. That means that when the motor cools down to a safe operating temperature, the motor automatically restarts.
The Puddle Sucker uses a semi vortex design impeller that features a “high-gap structure” that makes it highly resistant to abrasion, and performance is largely unaffected by minor wear. The motor is protected by a dual inside mechanical seal, located in the oil chamber with two silicon carbide sealing faces.
An Oil Lifter, developed exclusively by Tsurumi, acts as a lubricating device for the mechanical seal. Utilising the centrifugal force of the shaft seal, the Oil Lifter forcibly supplies lubricating oil to the upper seal faces, even at low lubricant levels. This amazingly simple device ensures lubrication and cooling and extends the length of time between inspections and services substantially.
Another important Tsurumi feature is an anti wicking block provided at the cable entry section of the motor chamber. Even if the cable jacket becomes damaged this device prevents water from travelling into the motor chamber through capillary action.
