Engineering Expertise in Action
Every project we deliver starts with a challenge — and a customer who needs a solution they can depend on. From offshore flushing systems and hydrostatic test units to bespoke high-pressure packages, each Flowplant project showcases our ability to design, manufacture, and support equipment that performs in the toughest environments. Explore some of our recent projects below to see how we turn complex engineering requirements into reliable, real-world solutions.
High Flow Rates | Low Pressure
A major offshore project required a flushing unit capable of delivering exceptionally high flow rates at low pressure. Flowplant engineered its largest flushing system to date — a progressive cavity pump unit with integrated heating and filtration — providing a reliable, compliant solution for hot oil flushing in demanding oil and gas environments.
Built within a DNV 2.7-1 certified stainless steel crashframe, the system combines a 3,500–4,000 litre heated tank and high-performance filtration to meet strict offshore cleanliness standards. Designed, manufactured, and tested at Flowplant’s Salisbury facility, the project demonstrates our capability to deliver large-scale, bespoke systems that enhance efficiency, reliability, and operator confidence in challenging conditions.
Hydrostatic Testing | Optimised Efficiency
Flowplant designed and built a 700-bar high-flow unit specifically engineered for hydrostatic testing applications. Developed to streamline testing and reduce downtime, the system delivers exceptional pressure performance with total reliability. Every aspect of the unit — from design and build to final testing — was completed in our Salisbury facility, ensuring precision, safety, and durability at every stage.
Tailor-made to meet demanding hydro test requirements, this bespoke unit highlights Flowplant’s ability to turn complex challenges into innovative, high-performance solutions. Combining cutting-edge engineering with practical functionality, it represents another proud achievement for the Flowplant team and a benchmark in efficient, customer-focused system design.

High Pressure | Built for Reliability
Flowplant engineered two high-performance flushing units powered by the Harben P-Type radial piston diaphragm pump. Built in the UK, they feature stainless steel tanks, dual-stage filtration to NAS 1638 Class 6, and integrated cooling for consistent performance. Compact, reliable, and easy to operate, these units highlight Flowplant’s expertise in custom-engineered flushing solutions.
Each unit was designed to deliver precise flow and cleanliness control for demanding industrial applications, ensuring reliability in environments where performance and fluid quality are critical. Supplied complete with pressure regulation, fluid sampling, and safety monitoring, these systems demonstrate Flowplant’s capability to design and manufacture robust, efficient, and operator-friendly equipment tailored to specific customer needs.
