Introduction
Oil and gas refineries operate under extreme process conditions, handling a wide range of fluids with varying viscosities, temperatures, and pressures. Delta PD Pumps are widely deployed across refinery units to ensure safe, reliable, and continuous transfer of critical hydrocarbons and process fluids.
Designed for demanding refinery environments, Delta PD pumps deliver steady, pulse-free flow, precise control at low and high capacities, and excellent performance with high-viscosity and lubricating fluids. Their rugged construction and high mechanical efficiency make them ideal for 24/7 continuous-duty operations.
Delta PD Pumps support numerous refinery applications including fuel oil transfer, crude oil circulation, lube oil systems, seal oil systems, and auxiliary services, helping refineries achieve operational reliability, reduced maintenance, and enhanced equipment protection.
With proven performance, compliance with industry standards, and a focus on operational safety, Delta PD Pumps are a dependable solution for upstream, midstream, and downstream refinery applications.
Refinery /Oil and Gas
Application of Crude Oil and Asphalt transfer
Delta PD Pumps—including Twin Screw, External Gear, and Single Screw Pumps—are widely used in oil & gas refineries for the reliable transfer of crude oil, asphalt, bitumen, and other heavy hydrocarbons.
They ensure smooth, non-pulsating flow, handle high-viscosity and high-temperature fluids, and support operations such as:
- Crude oil transfer from storage tanks to processing units
- Asphalt/bitumen pumping at elevated temperatures
- Loading & unloading of tankers, wagons, and trucks
- Transfer to heaters, blending units, and storage
Their robust design, ability to handle impurities, and high suction capabilities make them ideal for demanding refinery environments.

Application for Well Gathering
Delta PD Suction Booster Pumps—using Triple Screw Pumps or External Gear Pumps—are installed at the refinery’s inlet manifold to maintain a stable and positive suction pressure for downstream transfer pumps. These pumps ensure uninterrupted flow of crude oil, fuel oil, or other process fluids by eliminating suction fluctuations caused by long pipeline runs, tank level variations, or high‐viscosity fluids.
They provide smooth, pulse-free flow, enhance NPSH conditions, prevent cavitation, and improve overall pumping efficiency and equipment life in refinery operations.

Barge / Tanker Loading and Unloading
Delta PD Pumps—specifically Twin Screw Pumps and External Gear Pumps—are essential for loading and unloading operations in oil & gas terminals. These pumps deliver:
- High suction lift for quick stripping of tanks
- Smooth, pulsation-free flow ideal for long-distance marine transfer
- Ability to handle a wide viscosity range (LDO, HSD, FO, Crude, Bitumen, etc.)
- Reliable operation under fluctuating temperature and pressure conditions
This makes them perfectly suited for jetty unloading systems, barge loading arms, tanker discharge manifolds, and bulk storage terminal pipelines.

Lube Oil dewaxing
Delta PD Twin Screw Pumps are used in refinery dewaxing units to transfer high-viscosity lube oils, waxy distillates, and solvent-rich mixtures at controlled, pulse-free flow. Their gentle handling, ability to work with variable viscosities, and excellent suction characteristics make them ideal for feeding filters, pumps, chillers, and dewaxing reactors. These pumps ensure reliable circulation of dewaxed oil and waxy streams even at low temperatures, maintaining continuous refinery operation.

Pipeline Injection
Delta PD Twin Screw and Triple Screw Pumps are used to inject crude oil, refined products, and other viscous fluids into long-distance pipelines. They provide high, stable discharge pressure, ensure pulse-free flow, and maintain reliable, continuous transfer required for pipeline transportation in oil & gas refineries.

Crude Distillation
Delta PD Twin Screw Pumps are used in crude distillation units (CDU) to efficiently handle a wide range of hydrocarbons—from light fractions to highly viscous, heavy crude. Their non-pulsating, smooth flow capability makes them ideal for:
- Feed pumping of crude oil into the distillation tower
- Transfer of hot, heavy fractions like atmospheric residue
- Handling multi-phase fluids containing gas, vapors, or entrained solids
- High-temperature service without performance loss
- Stable operation under varying suction conditions
Twin screw pumps ensure reliable, continuous, and gentle fluid handling, protecting downstream equipment and maintaining stable crude distillation throughout.
