Cokebusters’ Double Pumping Units (DPUs) are the core enabling technology behind our mechanical pigging and integrated inspection services combined delivery.
As a specialist services contractor, Cokebusters deploys purpose-built industrial double pumping units designed to deliver safe, controlled and efficient mechanical pigging across complex assets.
Commonly referred to as a double pumping unit, each DPU is a trailer-mounted or containerised system that contains all the equipment and functionality required to deploy mechanical scraper pigs reliably in demanding industrial environments.
Designed for flexibility and reliability, our pumping units allow Cokebusters to arrive on site fully equipped to deliver industrial pumping services across a wide range of assets, including fired heaters, steam generators, process pipework and pipelines.
Each Double Pumping Unit comprises four fundamental elements:
The twin pumping configuration enables controlled, bi-directional operation and supports simultaneous multi-pass decoking or descaling activities, making Cokebusters a recognised pumping unit specialist in mechanical pigging applications.
This self-contained design enables operations to be executed with minimal reliance on site infrastructure, reducing complexity and improving predictability.
All Cokebusters double pumping units are designed, built and maintained in-house. This ensures complete control over specification, quality and ongoing development, while allowing any mechanical or operational interventions to be carried out by Cokebusters personnel directly on site.
DPUs are equipped with on-board two-stage filtration capable of separating debris down to 750 microns during mechanical pigging operations.
Dedicated water tanks are used to segregate fresh make-up water from contaminated return water. As water circulates through the asset to propel scraper pigs and transport removed debris, filtration ensures that solids are recovered for responsible handling and disposal, supporting both operational efficiency and environmental performance.
This integrated approach forms part of Cokebusters’ broader pumping system solutions for mechanical decoking, descaling and pipeline applications.
Each Double Pumping Unit is fitted with Cokebusters’ proprietary InnerVision™ monitoring system.
Integrated pressure and flow sensors feed directly into InnerVision™, allowing operators to monitor operating parameters in real time and track pig location and velocity throughout each pass. This data-driven approach provides valuable insight into system behaviour, enabling informed decision-making, optimisation of cleaning efficiency and avoidance of unnecessary pigging runs.
Cokebusters’ fleet of Double Pumping Units are strategically located within the regions we serve, enabling rapid mobilisation and responsive delivery of double pumping unit services.
Because all equipment is designed and built in-house, DPUs can be configured, adapted and maintained to suit specific project requirements. This flexibility is a key advantage when delivering pipeline pumping unit services and other time-critical industrial operations.
