Materials of Construction
Pumps are manufactured in different materials of construction depending on the liquid to be handled. All parts coming in contact with liquid are selected to ensure compatibility.
Wetted casings are available in cast iron, 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 designs Cardon joints complete sealed against liquid.

Basic Design, Principle of Operation
UTPSL Eccentric Helical Rotor Pumps are Self Priming, Rotary, Valve less Positive Displacement pumps having two pumping elements Rubber Stator and Metallic Rotor. Stator is having helical profile with pitch double to Rotor pitch resulting in cavities, which carry the liquid. EH pumps are basic design pumps with flange connection usually installed horizontally. Inlet and outlet ports can be interchanged by simply changing direction of rotation of motor. Pumps are suitable for drive by Motor/Engine thro Direct Coupling or V' Belt/Pulley.

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

Special Features / Advantages
Longer Pitch and smaller diameter of rotor makes UTPSL pumps highly reliable with Small Initial Starting Torque, Higher Mechanical Efficiency, Capability to handle large proportions of solids, Small Radial Thrust, Low Rubbing Velocity, Less Wear, Lower Axial Thrust, Smaller Unbalance, Higher Suction Lift.

Eccentric Helical Rotor Pumps of type EH are available in different size and stages depending upon the requirement of pressure
