EATON Danfoss L2 Series Gear Pumps
Eaton Danfoss L2 Series gear pumps act like positive displacement (PD) pumps to transfer fluids mechanically using their interlocking cogs & gears and the cyclic pumping action. The smooth pulse-free flow is proportional to the gear's rotational speed. These gear pumps are suitable for use ...in agricultural, material handling, natural resources & civil engineering applications.Read more

Working Mechanism
- Eaton Danfoss L2 Series gear pumps use their rotating cogs & gears to create a liquid seal with the pump's casing.
- This generates suction at a pump's inlet.
- Fluid gets drawn into the pump while being enclosed in the cavities generated by the rotating gears.
- This leads to fluid transfer to the discharge port.
Features
- Eaton Danfoss L2 Series gear pumps are compact and feature fewer moving parts.
- They are ideal for pumping high-viscosity fluids & oils.
- These gear pumps have aluminium housing with clockwise (CW) / counterclockwise (CCW) shaft rotation.
- They have plain backplate or double pump configuration.
- These gear pumps have a maximum continuous pressure of 248 bar (3600 PSI) & a maximum intermittent pressure of 276 bar (4000 PSI).
- They have a maximum continuous inlet temperature of 107 degrees C (225 degrees C) and a minimum operating temperature of -29 degrees C (-20 degrees F). High temperatures can cause thermal expansion of the casing & gears for reduced clearances inside a pump, resulting in increased wear or pump failure.
Frequently Asked Questions
What are the things to inspect these Eaton Danfoss L2 Series gear pumps?
