Steel Plant applications for Delta PD Pumps
In Steel Plants, Delta PD Pumps are the “heart” of critical lubrication and hydraulic systems. Their positive displacement design ensures a constant, pulsation-free flow, which is vital for protecting the massive, expensive machinery found in mills and furnaces.
Specific applications are
Hot Strip Mill & Rod Mill
These mills operate at high speeds and extreme temperatures.
- Main Bearing Lubrication: Supplies high-pressure oil to the backup roll and work roll bearings. The constant flow ensures a hydrodynamic film that prevents metal-to-metal contact under the crushing forces of the rolling process
- Gearbox Lubrication: Circulates oil through the heavy-duty reduction gears that drive the mill stands
- Hydraulic Roll Gap Control: Powers the high-precision hydraulic cylinders that adjust the gap between rolls to maintain precise thickness (gauge) of the steel strip or rod.
Pumps used for this Application
Ball Mill (Grinding)
- Trunnion Bearing Lubrication: Ball mills used for grinding ore or coal rely on 3-screw pumps to feed high-viscosity oil to the trunnion bearings. These pumps must handle the high viscosity of the oil even in colder startup conditions.
Pumps used for this Application
Coke Oven Plant
- Exhauster Lubrication: The gas exhausters are mission-critical. Delta pumps provide a reliable, pulse-free flow of lube oil to the exhauster bearings and seals
- Pusher Car Hydraulics: Used in the hydraulic systems of the pusher cars, door extractors, and charging cars that move the coal and coke.
- Fuel Oil Transfer: Transferring and boosting heavy fuel oils (HFO/LDO) used for heating the ovens.
Pumps used for this Application
Sinter Plant
- Pallet Car Lubrication: Ensures a continuous supply of grease or heavy oil to the wheels and tracks of the sinter strand.
- Fan & Exhauster Bearings: Sinter plants use massive fans for suction. 3-screw pumps provide reliable lubrication to these high-speed bearings to prevent catastrophic failure.
- Hydraulic Gates: Used to operate the hydraulic gates and feeders for the raw material mix.
Pumps used for this Application
Blooming & Bar Mill
- Heavy Duty Lubrication: Similar to hot strip mills, but handling much larger, heavier "blooms." Delta pumps are used for Jacking Oil Services, where high pressure is used to "lift" the massive rotors or rolls during startup to prevent dry friction damage.
- Scale Breaker Hydraulics: Used in high-pressure hydraulic systems to operate the scale breakers that remove iron oxide from the surface of the hot steel.
Pumps used for this Application
Blast Furnace
- Tuyere Cooling Water Control: While main cooling systems may use other technologies, the high-pressure hydraulic controls for valves often utilize 3-screw pumps.
- Tapping Machine Hydraulics: Powers the hydraulic mud guns and drilling machines used to "tap" the molten iron from the furnace.
- Lubrication for Blowers: Provides lubrication to the massive blowers that provide the "blast" of air into the furnace.

UTILITIES FOR STEEL PLANT
Fuel Firing Pumps
Delta 3-screw pumps are widely used as fuel firing pumps in steel plants to supply a continuous, stable flow of fuel oil (HFO, LDO, or furnace oil) to burners and furnaces. These pumps transfer fuel from storage or day tanks to firing systems at the required pressure and temperature, ensuring efficient and controlled combustion.
With their pulse-free operation, high-pressure capability, and excellent handling of viscous fuels, 3-screw pumps support reliable furnace performance in applications such as reheating furnaces, blast furnaces, and coke oven plants. Their robust design ensures smooth burner operation, reduced vibration, and improved fuel efficiency, even under harsh steel plant operating conditions.
Fuel oil unloading and transfer operations
These pumps can handle both light and heavy fuel oils, even when viscosity varies due to temperature changes. Their self-priming capability, smooth pulsation-free flow, and ability to operate at higher pressures make them highly reliable for continuous industrial operations.
With robust design and specialised metallurgy, Delta PD Twin Screw Pumps offer high efficiency, low maintenance, and long service life, ensuring a dependable fuel supply for critical processes in steel plants.
