Industrial Internal Gear Pumps Designed for Demanding Applications

LubeTech pumps are based on the principle of the internal gear mechanism:

  • The medium enters the pump through a vacuum created by the rotation of the gear wheels.
  • The liquid fills the space between the teeth of the rotor and the external gear element (idler), moving along the casing.
  • The liquid is transported around from the suction side to the discharge side, where it is pushed out under pressure.
  • A distinctive feature of these pumps is the "crescent" element separating the suction and discharge chambers—increasing efficiency and minimizing pulsations.

Advantages:

  • Low flow pulsations
  • Self-priming
  • Reversing Feature
    Capability to operate in both directions (L & C versions)
Reversing Feature
When Shaft Rotation Changes the Idler Carrier Automatically Rotates 180°and Changes the Direction of Flow internally. (L and C Series)

L Series – Compact and Versatile

The L series pumps are compact internal gear pumps designed for precision lubrication, fluid transfer, and oil circulation applications. The "U-shape" design allows the pump to maintain a flooded state, which promotes immediate start-up and reliable medium delivery. Made of grey cast iron, they offer durability even in harsh industrial conditions.

  • Flow rate: 49 / 318 lpm – 12 / 84 gpm
  • Pressure: Up to 20,7 bar / 3000 psi
  • Viscosity (cSt.): Up to 5390
  • Temperature: Up to 190°C / 374°F

Applications: Lubrication systems for compressors and turbines, transfer of diesel oil, pre-lube systems in industrial machines..
