Reliable Downstream pump solutions

In the downstream oil & gas sector, progressing cavity pumps (PCPs) offer an advanced and robust solution for surface transfer applications. From refining processes to petrochemicals, the downstream segment demands pumping systems capable of managing viscous, abrasive and shear-sensitive fluids without compromising performance or safety.

PCM’s range of progressing cavity pumps is engineered to deliver smooth, pulsation-free flow with high volumetric efficiency. They are suitable for handling challenging fluids such as catalysts, sludges, emulsions, polymers, heavy hydrocarbons, and wastewater containing solids.

Challenges in Downstream Operations

Handling highly viscous such as heavy fuel oils

Downstream processes frequently involve the handling of highly viscous fluids, including , heavy fuel oils.

These substances pose a significant challenge for conventional centrifugal pumps, which suffer from loss of efficiency and increased wear under such conditions.

Progressing cavity pumps (PCPs), with their positive displacement mechanism, are uniquely equipped to deliver a consistent, pulsation-free flow, regardless of viscosity variations.

Viscous and abrasive products

In downstream processes, fluid composition often varies. PCM surface transfer pumps ensure a consistent flow rate, even when viscosity, solids content, or pressure fluctuate — whether handling hydrocarbons, oil and water emulsions, or sand-laden fluids.

Thanks to their progressing cavity pump (PCP) technology, PCM pumps can efficiently transfer all types of fluids, regardless of their viscosity, abrasiveness, or composition.

Waste water treatment

In downstream oil and gas applications, wastewater treatment presents a significant challenge due to the complex mixture of oil, water, and suspended solids. Efficient separation of industrial oil and water emulsions is essential to meet environmental regulations and reduce operating costs.

Progressing cavity pumps play a key role by providing gentle, low-shear transfer that preserves droplet integrity and enhances separator performance.

Typical applications in the downstream operations

Refinery and Petrochemical Applications

In downstream operations, progressing cavity pumps are increasingly valued for their ability to handle viscous feedstocks, chemical additives, and complex byproducts with minimal shear and high flow stability. PCPs excel at transferring bitumen, pitch, heavy vacuum gas oil (HVGO), and slurries

PCPs are also ideal for dosing or circulating aggressive process fluids where chemical compatibility and precise metering are essential. Their ability to generate high differential pressure enables long-distance or high-elevation transfer without the need for booster stations or heating systems.

Tank Farm Operations

In tank farms, where hydrocarbons, chemical intermediates, and end products are stored, blended, or transferred, PCM’s progressing cavity pumps provide operational flexibility and safety. These storage and distribution facilities often require reliable pumps for tank cleaning and bottom sludge recovery, all of which are application areas where PCPs outperform traditional solutions.

PCM PCPs can be installed horizontally or vertically into tank pits, or underground.
