Triple Screw Pumps Dealers in Naigaon, Mumbai

GENERAL INFORMATION (TH 1X PUMPS) WORKING PRINCIPLE Triple Screw Pumps are positive displacement pumps of very simple design They consist of three rotating parts only the rotors" which turn in their precisely machined housing bores. The rotors are of double start screws, continuously meshing to form delivery chambers, which move constant y from the suction to the pressure / discharge side. Constant volume oi the chambers and the uniformity of the movement allow an even flow The pumps remain therefore near silent in operation and almost free of pulsation, even at high speed The Principle of screw pump and its accurate profiles warrant high suction power. Axial loads on the rotor are compensates by adequate design of the bearing part. All the radial loads are self-compensated. APPLICATION Triple Screw Pumps, type TH are used for die transfer of fluids with lubricating properties, as well as for generating pressure in hydraulic units or overcoming pressure in the hydraulic circuits. Main Industrial uses are in: Power Hydraulics Power Generation Lube industries Machine Tools Windmill Oil & Gas Compressor Lubrication Presses Marine Filtration TYPICAL LIQUIDS All kind of Bunker Oil, Engine oil, Furnace oil, Heating oil, Hydraulic Oils, High Viscosity Lubrication Oil, Mineral oil, Synthetic Oil, 0il Water Emulsions and Fuel 0ils, Diesel Oil, LSHS, LDO. MATERIAL OF CONSTRUCTION Pump Housing : Carbon Steel, Cast Iron, Stainless Steel Liner : Alluminium Alloy / Cast Iron / Copper Rotors : Main Screw : Alloy Steel, Hardened Steel and Surface Treated Steel Idler Screw : Hardened Steel, Surface Treated Steel Shaft Sealing : Mechanical Seal / Lip Seal with Elastomers in Viton, EPDM & Nitrile / Gland Pack/Graphoil Rings Mounting Frames : Fabricated Steel Relief Valve Parts : In Steel & Cast Iron EXECUTION The pumps here described may be incorporated in various housings and supplied as Foot, Flange or Pedestal Pumps. We also supply cast or welded housings to your specifications. To adapt the pumps to various applications, they can be fitted with the following seal variations: Radial shaft seals Gland packings (stuffing box) Mechanical seals PRESSURES Upto 120 bar are admissible. INSTALLATION Screw-Pumps work perfectly in any position, provided suction and pressure lines are arranged in a way that prevents emptying of the pump when at a standstill. DIRECTION OF ROTATION Clockwise from the Shaft End of the Pump (Standard) Anticlockwise from the Shaft End of the Pump (On Request / Non Standard) DRIVE In general the pumps are connected with a flexible coupling to a foot or flange mounted motor. Radial loads onto the shaft end are not permissible, unless when absorbed by an additional external bearing, e.g. in case of pump drive by belts or gears. SPEED OF ROTATION Shaft Speed Ranging from 500-3600 RPM Do not exceed 1500 RPM when pumping residual fuels, crude oil due to the presence of abrasives and contaminants. VISCOSITY Normal range 21,5 to 385 cSt. Depending on type, pressure, speed and suction conditions, fluids with viscosities ranging from 6 to 3800 cSt may be pumped. Regarding viscosities outside the normal range. Please consult us! TEMPERATURE RANGE When fitted with standard radial shaft seals, up to 90 Deg C. Depending on operating conditions, temperatures as high as 180 deg C are permissible. Please ask us! Cooling Jacket & Heating Jacket for the pump body & covers can be provided for easing the cold start of the pump and for continuously pumping liquids at high temperature. SUCTION LIFT OR INLET PRESSURE For speed between 1000 and 1700 r.p.m and viscosities below 385 cSt you may reckon with an absolute manometric suction lift of maximum 0,5 bar. For other speeds or viscosities. Please contact us! The inlet pressure should not exceed +0,5 bar, when radial shaft seals are used. For higher inlet pressures we offer gland packings or mechanical seals. If the suction lift condition exceeds the pump capability, cavitation will occur resulting in noise and possible pump damage. SUCTION AND PRESSURE LINES The cross section of the suction line should be such that fluid velocity nowhere exceeds 1 m/sec. In the pressure line velocity should not exceed 5 m/sec. PRESSURE RELIEF VALVE All housings described here may be obtained with or without pressure relief valve, which we supply at your option as by-pass valve, connected to the suction chamber, or as return valve, conducting the fluid by a separate connection to the tank. When a larger quantity should have to pass through the valve for more than 10 seconds, a return valve has to be fitted, to avoid an undue rise in temperature. FILTRATION The pumps must be protected against solid particles in the fluid by suitable suction filters. The mesh width should be 0.1 mm and care has to be taken that even with a contaminated filter the admissible suction lift capability is not exceeded.

Delta Corporation group is the pioneer in the field of Positive Displacement Rotary pumps since 1968. They introduced for the first time in India the concept of "Three Screw Pumps" in 1970's. Foreseeing the growing demand for totally reliable fuel and lube oil pumps for Thermal and Hydel Power Plants, Fertilizer, Chemical and Steel Projects a beginning was made by importing critical components and building pumps locally. Over decades, thousands of Three Screw pumps have been manufactured and delivered. Valuable experience was gained and modern manufacturing and testing facilities established under guidance from world-renowned European companies. Over the years the market has grown considerably and the field of applications has become more diverse for these pumps, compelling innovations in the design and production of the pumps to answer the demands of the market. In line with the current requirements, Delta is proud to present to this mature market, reliable, low noise, low vibration and low cost three screw pumps produced as per the latest state of the art manufacturing practices. We have partnered with Settima Meccnaica s.r.l who are leading manufacturers of screw pumps in Europe since 1978. Settima has focus on low noise, low pulsation pumps which help increase the overall efficiency and life of the pumps Settima-Delta pumps are on the OEM list of major plant and equipment manufacturers, consulting organizations and has met with approvals from third party inspection agencies - national and international. Working Principle Settima-Delta Three Screw pumps employ just three screw elements - one power screw and two idler screws running in the three precision bores in the housing or liner. The screws are so profiled that they form a liquid tight seal between the thread. As the screws rotate, pockets/ cavities are formed where liquid gets trapped and conveyed from one end of the infinite stroke. This results in smooth, pulsation free flow with extremely low noise and vibration levels, almost impossible to be achieved by any other design of positive displacement or other types. The power rotor does not drive the idlers as commonly believed. The hydraulic forces acting on screw flanks turn the idlers torquelessly thus reducing the friction. The idlers simply roll over the root diameter of idler dia.reduce the unit pressure, centralize the power rotor and absorb the radial loads. A balance piston integrally machined on power rotor takes care of axial thrusts. While in operation, the screws are in hydrodynamic balance on film lubrication and do not require any additional bearings. The one ball bearing often used is only for axial positioning of rotor and safer operation of mechanical seals. Small rotor dimensions enable the pump to be operated at high speeds directly coupled 3000 or 3600 RPM motors or other prime movers. Such unique design and features has demonstrated excellent reliability with pumps in operation continuously non-stop for decades together without replacement of any components or maintenance on clean fluids.
