Delta PD Pumps Pvt. Ltd. Wadala, Mumbai, Maharashtra

A pair of specially profiled screw, machined integral from solid stock and well supported on antifriction bearings run in precision bored interchangeable casing liners. Each screw set has one right hand and one left hand screw engaging with a similar but opposite hand screw pair.  A pair of hardened and profile ground timing gears synchronize the screws to maintain a small but positive clearance between the flanks thus ensuring no metal to metal contact. The pumps can therefore run dry for sometime without any damage. This unique feature enables to run the pump even dry and handle fluids that do not have enough lubricating value and also very low or high viscous products.  Consequently, since there is no metal to metal contact; wear and tear is reduced to the minimum, ensuring extremely long service life. With two pairs of screws running in the same casing, the internal velocities are very small - consequently the NPSHR is practically the lowest even when the pumps run at motor speeds and while handling viscous products. Opposed screw pitches totally eliminate axial thrusts. Relatively small diameters of screws enables the pump to operate at high speeds directly coupled to prime movers - without the need for speed reducers even while handling high sealing’s always under suction pressure, thus making use of simple, inexpensive seals. The axial flow without turbulence, rotation, churning, chewing guarantees gentle handling of products. Noise and vibration or ---- levels are about the lowest. Positive clearance between running parts makes it easier to construct the pump in different materials safely, especially in stainless steel, without the fear of seizing. Thus a variety of fluids can easily be handled by selecting the right materials of construction.     Typical Parameters Temperature: -30 to +350°C Viscosity: 1 cSt to 50,000 cSt or more Capacity: 20 to 500 m3/hr Pressure: Normal 16 bar/ 24bar, with special designs up to 50 bar Specialties: Partial heating/ complete heating/ cooling arrangements Sealing: Stuffing box/ mechanical seal with or without quenching/ heating/ cooling Mounting: Horizontal foot mount/ vertical pedestal Accessories: Relief valves, base frame, coupling, coupling guard, companion flanges, pressure gauges, electric motor/ diesel engines, variable speed drives and as per customer requirements.

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.     Typical Applications Fuel Oil Service: Fuel oil burner service for Thermal Power Plant/ Industrial Package, Boilers, Furnaces, Kilns and Combustion systems. Fuel transfer and booster service for Captive Diesel/ Gas Turbine Plants and Industrial Combustion Systems, Fuel Oil Circulations and Centrifuge Feeding. Tank farm tank to tank transfers. Hydraulic Duties: Hydraulic governing service for Water Turbines, Inlet Penstock Valves. Low and medium pressure hydraulic applications, high pressure jacking oil service for rotor lifting for Turbines/ Compressors/ Alternators. Lubricating Duty: Pressure lubrication and cooling of bearings for Turbo Machinery, Gear Boxes, Bearing Lubrication of Coal Mills, ID/FD Fans, Diesel Engines, Steel Rolling Mills, Air pre-heater guide bearings, Compressors.

The pumping elements are rotor and stator. The single helical rotor rolls eccentrically in a double threaded helix stator of twice the pitch length.  A series of sealed cavities 180° apart are created that appear to progress from suction to discharge during one rotation of rotor.  The opposing cavities fill and empty simultaneously resulting in a pulsation less flow.  The fluid travels axially with relatively low velocity and minimal agitation.  The stator is made of a resilient elastomeric material and bonded to the stator tube.  The important feature of the pumping principle is the ability to handle slurries and solid particles. The elastomeric stator also permits passage of solid particles due to elastomeric deformation.

The geometry of the two rotors partitions the volume between them into N different dynamically-changing volumes. During the assembly's rotation cycle, each of these volumes changes continuously, so any given volume first increases, and then decreases.

Certification : ISO 9001:2008

Condition : New

Pressure : Upto 7 Bar

Applications : Lube Oil Transfer, Circulation

Condition : New

Pressure : 10-20Bar

Type : Rotary Gear Pump

Only two rotating parts having principle of gear within gear but without crescent. The inner rotor is located off-center and both rotors rotate.  The geometry of the two rotors partitions the volume between them into N different dynamically-changing volumes. During the assembly's rotation cycle, each of these volumes changes continuously, so any given volume first increases, and then decreases. An increase creates a vacuum. This vacuum creates suction, and hence, this part of the cycle is where the intake is located. As a volume decreases compression occurs. The Flow of liquid is axial through the elements.  In built features of speed reduction as pinion is rotated at prime mover speed and outer gear rotates at lower speed.                               TYPICAL APPLICATIONS   Transfer and Barrel unloading Pressure lubricating & cooling of bearings & gear boxes. Pumping, heating, cooling and filtering units. Pre-lubrication of components of machinery before starting.

Delta DIG series employs proven Internal Gearing (Gear within Gear) principle for pumping. The main gear is keyed to the drive shaft, and rotates concentric in the pump casing. Idler is located on an eccentric pin on the front cover to rotate freely and meshes with main gear when assembled. A crescent shaped partition precision machined on the front cover maintains a small, but positive clearance to achieve perfect scaling between parts. As the gears come out of mesh, a partial vacuum is created, forcing the fluid to rush into the pump casing and fill in the voids between the teeth. Both gears rotating in the same direction of rotation gently transfer the fluid to the delivery port. The resulting action is a smooth-steady flow; low in pulsation, noise and vibration. Single shaft design well supported on outboard bearing (except for one inside sleeve bearing) enables to pump products even with poor lubricating value unlike in the external gear pumps. External bearing construction offers easy access the pump components i.e., rotor set and even pump casing simply by removing the front cover without disturbing drive parts, bearings etc., and in place. Block pump mounted integrally on hollow shaft gearbox automatically reduces the speed (in several ratios) and enables even the pump rotor to be pulled out without disturbing the drive! It is easily possible to jacket front and rear covers for products heating - thus making the design unique and versatile - ideally suited for process pumping.

The DIG series is modular developed with excellent interchangeability. The pump is available either as bracket mounted 'BM' or gearbox mounted 'GM" models.

External gear pump uses two identical gears rotating against each other -- one gear is driven by a motor and it in turn drives the other gear. Each gear is supported by a shaft with bearings on both sides of the gear. As the gears come out of mesh, they create expanding volume on the inlet side of the pump. Liquid flows into the cavity and is trapped by the gear teeth as they rotate.

External gear pump uses two identical gears rotating against each other -- one gear is driven by a motor and it in turn drives the other gear.  Each gear is supported by a shaft with bearings on both sides of the gear.  As the gears come out of mesh, they create expanding volume on the inlet side of the pump. Liquid flows into the cavity and is trapped by the gear teeth as they rotate.  Liquid travels around the interior of the casing in the pockets between the teeth and the casing -- it does not pass between the gears.  Finally, the meshing of the gears forces liquid through the outlet port under pressure.
