Such unique design and features had demonstrated excellent reliability with pumps in operation continuously non- stop for decades together without replacement of any components or maintenance on clean fluids. Key features � benefits that reduce life cycle cost maximum reliability of system to increase revenue pumps delivers smooth flows with minimum pulsations hydraulically balanced screws lower maintenance costs by up to 50 % pumping elements contained in one cartridge assembly fast, easy replacement of parts reduced overhaul turn around time no timing gears required and fewer wearable parts one or no bearings required and fewer wearable parts versatility to meet customer specification custom design fabricated pump and per api standards a choice of shaft seals for every application mounting configurations to fit in any space limitations: horizontal, vertical, close coupled, sump in � line construction enables simplified piping arrangements ansi or din flanges one pump size designed to offer flexibility in flow specifications capacity : from 1 to 400 m3hr pressure : up to 64 kgcm2 viscosity : 1-1, 00,000 centi stokes temperature: up to 300 .c user industries cement industry power stations petro chemical refineries oil depots ship building industry rayon, staple fibres steel industries fertilizer industries paper mills food processing industries breweries bitumen and asphalt industries these pumps are designed for handling clear viscous liquids and are suitable for different pressures upto 70 bars. The pumping elements comprise of a power screw and two idler screws, running in a close fitting insert. The idler screws serve to maintain the closed chambers that pump the liquid. Each screw is provided with a drum so that axial forces are hydraulically balanced. The shaft seal chamber is connected internally to the inlet and the seal is therefore always subjected to the inlet and the seal is therefore always subject to inlet pressure only. The inserts screws and balancing bushes together with bearing and seals for a replaceable cartridge that is located inside a casing. The pumps can be supplied in a variety of materials of construction and for various mounting arrangements.

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.
