HS Series

Features

Tsurumi's HS Series, a submersible portable drainage pump, has the following features:

• Agitator

An agitator is provided on the end of the pump shaft. The agitator helps prevent air buildup inside the casing and also reduces clogging when solid objects enter the pump.

• 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 HS pumps.

• Continually Rated

The pump can run non stop 24/7 without overheating or cutting out.

• CWL (Continuous Water Level) 90mm

Only 90mm of water is required for the pump to run, reducing the chance of failure at low levels. This also allows the pump to drain to much lower levels than allowed by most pumps. 

• 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.

• Bearings

High grade bearings for high temperature operation are used. As the bearings are deep grooved and doubled shielded and covered permanently in grease, lubricating oil is not required.

• Pump structure

The semi vortex design of the HS minimises 'impeller lock' where foreign matter carried into the pump prevents rotation of the impeller. This design is resistant to wear and demonstrates minimum drop in performance even if impeller is worn.

• Motor protection device

Miniature thermal protectors (MTPs) are built into its motor and integrated in motor windings. The MTP will cut the motor circuit in the event of excessive heat.

• Materials of construction

Use of light and strong materials is used throughout the entire pump. This ensures the pump is easily transportable.

• Cooling system / discharge port

The spiral design of the pump allows sand and silt laden water to pass through efficiently.

• 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.

Applications

• General construction dewatering
• Cellar or basement drainage on buildings
• Transfer and drainage of stormwater
• Circulation in decorative waterfalls and fountains
• Drainage of treated water in water treatment plants
