Single Screw Pumps ER Model

Applications
For Transfer of Thick Paste & Pigments, Cake Mix, Butter, Grease, Waste Asbestos, Fruit Pulp, Petroleum Jelly, Explosive Slurry, Pulp with Low Moisture Content, SewageWaste and can handle Extremely Viscous, Pasty or Hardly Pump able Media, or Media with a Content of Solid Matter (up to 60% Drying Agent), this range of applications covers all branches of industry etc.

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. ER pumps are having special Hopper design Casing and Universal Joint Shaft with conveyor and they are and are suitable for operation with flooded suction condition installed horizontally only. Which pushes medium to pumping elements Pumps are suitable for drive by Motor/Engine thro Direct Coupling or V' Belt/Pulley. 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, ER pumps are not suitable for dry running.

Industries
Building Industry, Ship Building, Starch Factories, Paper & Cellulose Industry, Pharmaceutical Industry, Plastic Industry, Sewage & Clarification Techniques, Soap & Fats Industry, Sugar Refineries,Water Treatment Plants, Food & Food Processing Industries and many others.

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 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 materials as gland packing or mechanical seal is available.
For hygienic application all part can be constructed in stainless steel material with a special type of noncontamination stator.
UTPSL pumps are having two special design Cardon joints completly sealed against liquid.

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, Open Hopper at Inlet with large fitment at bottom, Low radial thrust, Low rubbing velocity, Less wear, Lower axial thrust, Smaller unbalance, Quieter operation, Higher Suction Lift
