Basic Design, Principle of Operation
UTPSL Eccentric Helical Rotor Pumps are Self Priming, Rotary, Valve less Positive Displacement pumps having two pumping element Rubber Stator and Metallic Rotor. Stator is having helical profile with pitch double to Rotor pitch resulting in cavities, which carry the liquid vertically Mounted. EU pumps are specifically designed for emptying barrels, containers or wells having low or highly viscous media with or without solid or fibrous components. The Drive unit is directly mounted on the pump body and the whole unit can be suspended and lowered in the container or well. Running at low speed, pumps have vibration free operation.
In the Cross-section, stator and rotor contact each other at two points which, viewed axially, are lines of contact or “sealing”.
When the rotors turns, this geometry resolves into tandem chamber which are self-contained as also when pumps are stationary.

Because of Elastomer Stator, EU pumps are not suitable for dry running.

Materials of Construction
Pumps are manufactured in different materials of construction depending on the liquid to be handled. All parts in contact with liquid are selected to ensure compatibility.
Wetted casings are available in stainless steel, and carbon steel. Rotors are available in stainless steel, carbon steel hard chrome plated or nitrided steel. Stators are available in all types of elastomer material. Option of using sealing material, as gland packing material or mechanical seal is available.
UTPSL pumps are having two special design Cardon joints completly sealed against liquid.

Special Features / Advantages
Small Initial Starting Torque, Higher Mechanical Efficiency, Capability to handle large proportions of solids, Less radial thrust, Low rubbing velocity, Less wear, Lower axial thrust, Smaller unbalance, Quieter operation, Mounted directly over the well or container.

Performance
Eccentric Helical Rotor Pumps of type EU are available in different sizes and stages depending upon the requirement of pressure.
