LH-W 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 LHW 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 build-up caused by blockage of the impeller or by other overloading factors. CTPs are used in LH models up to LH 430W. The 430W uses a miniature thermal protector (MTP) to cut the motor circuit.

  • Cylindrical Channel

The whole channel maintains the motor cooling efficiency adequately high even during operations at a low water level. With the discharge port on its top, the pump can be installed in a narrow place.

  • Centre Flange Construction

Enables pump to be raised or lowered without disconnection from piping and stably installed true to its centre of gravity.

  • Dual impeller

Two impellers greatly increase the max head of the pump, making the LH-W suitable for deep wells and pumping from a large height.

Applications

  • General construction dewatering
  • Drainage in construction and mining sites
  • High head dewatering
  • Deep well dewatering
