Descripción del producto

Absolutely NO metal-to-metal contact between the moving screws as a small positive clearance is maintained between them. This ensures the pump very long operational service, resulting in no wear and tear of pump parts.

Pump capable of running dry

Screws are mounted on the timing gears and the speed of both the screws are therefore synchronized resulting in pulsation free, turbulent free flow

Flow of the liquid is always in the straight path

Sealing is situated at the suction pressure

Pump requires very low NPSH (Net Positive Suction Head)

The rotation of screws is perfectly balanced resulting in NO vibration and negligible noise.

Working Principle:

Twin Screw pump are robust in design and can handle variety of liquids with diverse operating parameters which generally cannot be handled by other Positive Displacement Pumps. The pump consists of a pair of profiled screws supported on anti-frictional bearings. 
Torque is transmitted from the driving shaft onto the driven shaft by hardened and ground timing gears arranged in the gear box. The speeds of both the screws are therefore synchronized. Timing gears maintains a small clearance between the moving screws, which enables the pump to even run dry. Since there is NO contact between the moving screws there is absolutely NO wear and tear of internal parts of the pump which gives extremely high trouble free and maintenance free operation for years together.

As both the screws move in opposite direction, the screws are perfectly balanced. The internal velocities are very low enabling the pump to operate with very low NPSH even when operating at full motor speed. The seals are located at the suction side and therefore are always under suction pressure due to the typical flow of the liquid, enhancing the life of the seals. The liquid is virtually carried between the screws in a straight path and hence it is not subjected to Turbulence, Churning or Chewing. With such balanced pump and NO contact between moving screws VIBRATION & NOISE are to the minimum.

A. Twin Screw Pump for clear and smooth liquids:

Types of Liquids handled:

·         Additives

·         Base Oils

·         Lubricating Oils

·         Paraffin Products

B.    Twin Screw Pump for liquids having no lubricating properties and also abrasive in nature:

For such liquid the gear box containing the timing gears are placed externally in a pool of oil, also the bearings are placed externally. This allows the pump to handle effectively any type of liquid.             

Types of Liquids handled:

·         Molasses

·         Polyester

·         Lyes

·         Carbon Black

·         Crude Oil

·         Bitumen

·         Black Oil

Twin Screw Pump Applications for different industries:

·         Petroleum Refineries

·         Tank Farm

·         Oil Blending Stations

·         Thermal Power industries

·         Fertilizer industries

·         Petrochemical industries

·         Ship Building industries

·         Shipping

·         Sugar Industries
