Clifton 8370 Submersible Drainage Pump Curve


  • Waterlight Cable Entry

An anti-wicking block is used to prevent water from entering the cable. Each conductor is then stripped and sealed in epoxy. This block stops moisture from reaching the motor chamber when the cable’s end is damaged or submerged.

  • Multi-Direction Discharge Coupling

The discharge can be switched between horizontal and vertical directions. A vertical discharge connection comes standard on pumps with 7.5 HP or more.

  • Motor Protector

The motor incorporates a circle thermal protector, which protects against overheating and dry-run.

  • Top Discharge and Double Housing Design

Designed to construct a water jacket that provides a maximum motor cooling effect for continuous operation at low water levels, this feature forms the cylindrical and slim shape of the pump. It enables the pump to be installed in confined spaces.

  • Submersible Motor

The air-filled motor, housed in a watertight casing, conforms to Class F insulation.

  • C3 Ball Bearings and Hardened SS Shaft

High-quality C3 ball bearings and the well-balanced, hardened stainless steel shaft enhance stability during continuous pumping operations.


  • Double Mechanical Seals

Located in the oil chamber, the device is made of quality materials with highly wear-resistant silicon carbide on the lower side, providing extra protection against leakage and dry-run.

  • Extra Protection for Mechanical Seals and Shaft

Lip seals and shaft sleeves are utilized for additional protection against wear.

  • High Chrome Iron Impeller

Clifton’s patent formula, ACrS Tech, is applied to all high chrome iron impellers. This technology increases wear resistance to particle abrasion.

  • Durable Outer Jacket and Strainer

The corrugated Outer Jacket and filter made from 304 stainless steel provide impact resistance to harsh handling and conditions. In pumps 7.5 HP and more extensive, a flat 304 stainless steel outer casing is provided as standard.

  • Food Grade Lubricant

Clifton adopts eco-friendly lubricants to minimize environmental impacts.
