KRS Series

Features

  • Anti-wicking cable entry

An anti-wicking block is provided at the cable entry of the pump. This unique feature protects the motor from ingress of water even if the cable sheath is damaged and the top of the cable is immersed in water.

  • Dual inside mechanical seal

The pump comes standard with a double mechanical seal. The seal is located completely within the oil chamber. This seal system does not rely on the pumped media for lubrication and cooling increasing the reliability and life of the seal.

  • OIL LIFTER (patent pending)

The OIL LIFTER stabilizes the mechanical seal by supplying oil to the top seal faces even if the lubricant in the oil chamber falls below the rated value. This is supplied standard in KRS pumps.

  • Motor protection device

Circle thermal protectors (CTPs) are built into its motor. The CTP will cut the motor circuit in the event of excessive heat buildup caused by blockage of the impeller or by other overloading factors.

  • Side channel - top discharge design

The benefit of this design is that water cools the motor as it flows past the inner motor housing. This will enable the pump to operate at low water levels for extended periods.

  • Cast iron construction

Pump impeller, suction cover and casing made of cast iron improves pump durability.

Applications

  • General construction dewatering
  • Drainage water from factories/plants
  • Water intake for industrial or irrigation uses
  • Pumping bentonite mixed water in foundation works (agitator type)
  • Draining water in mud or slurry (agitator type)
