Features

  • Grinding mechanism
    The pump has a grinding mechanism at the suction port, and it grinds solids finely operation. The grinder is made of chromium iron casting and is highly resistant to abrasion. Vortex impeller is used to reduce clogging. Four stage rotating cutter head fitted inside a fluted stationary shredding ring.

  • OIL LIFTER (patent pending)
    The OIL LIFTER stabilizes the function of the mechanical seal. It increases the life expectancy of the seal and extends the maintenance cycle.

  • Dual inside mechanical seal
    The pump is furnished with a dual inside mechanical seal located completely in an oil chamber. This seal system does not rely on the pumped media for the lubrication and cooling, which increases the reliability of the sealing.

  • Anti-wicking cable entry
    The pump has a rubber moulded anti-wicking clock at the cable entry section of the pump. This unique feature protects the motor from the ingress of water that may be caused by damage to the sheath of the cable.

  • Guide rail fitting version
    Guide rail fittings readily connect/disconnect the pump to/from the piping system only by lifting up and down the pump, allowing easy maintenance and inspection without the need to enter the sump. Pumps in this version have a ‘TOS’ identifier on top of their model codes.

  • Motor Protection
    A circle thermal protector (CTP) is installed in its motor. It automatically stops the motor in the event of an excessive heat build up in the motor, caused by blockage of the impeller or by other overloading factors.

Applications


  • Pressurised sewer system
  • Domestic or community sewage lift stations
  • Drainage of wastewater at factories, hotels, hospitals, shopping malls, etc.
