Strengthening MRMS Drainage Operations

SALISBURY, UK — Flowplant has successfully designed, built, and commissioned a bespoke Harben Century Trailer for MRMS. This powerful new addition significantly strengthens MRMS’s capability to deliver specialist drainage, culvert, and tank cleaning services across the UK.

Engineered around proven Harben pump technology, the high-performance unit provides the precise pressure and flow required for challenging infrastructure maintenance. As a result, MRMS can more effectively maintain critical drainage and utility assets in some of the UK’s most demanding environments.

Meeting the Demand for Specialist Drainage and Culvert Cleaning

Operating nationwide from strategically located bases in Bradford, Gloucester, and Bridgend, MRMS offers an extensive portfolio of specialist services. These include high-pressure water jetting, CCTV and manhole surveys and advanced surveying technologies.

To support its growing national operations, MRMS required a powerful yet reliable high-pressure jetting unit. Crucially, the machine needed to deliver exceptional cleaning performance while maintaining total operational flexibility.

Flowplant answered the challenge by building a custom-configured Harben Century Trailer engineered specifically for off-road culvert cleaning, heavy-duty drainage maintenance, and industrial tank cleaning.

Bespoke Engineering for Maximum Jetting Performance

At the core of the new unit is the industry-renowned Harben Century Series 8 radial piston diaphragm pump, capable of delivering up to 350 bar (5,000 psi) operating pressure at 136 litres per minute.

Flowplant paired this high-performance pump package with an efficient Perkins Stage V engine connected via a heavy-duty Davall gearbox. Together, this creates a robust powertrain built to handle continuous, intensive cleaning tasks.

The unique radial piston diaphragm design delivers several key operational benefits:

  • Smooth, consistent flow characteristics for maximum jetting efficiency.
  • Exceptional component reliability even when running on recycled or poor-quality water.
  • Long service life that minimises operational downtime in harsh environments.

Key Features Built for Operator Safety and Efficiency

Flowplant engineered the trailer with operator usability, safety, and reliability at the forefront. By consolidating all controls and instrumentation into an intuitive control station, operators gain real-time visibility over machine performance, ensuring both safety and efficiency on site.

Machine Highlights Include:

  • Harben Century Diaphragm Pump: Delivers 350 bar at 136 L/min.
  • Stage V Power Unit: Eco-friendly Perkins engine compliance.
  • Powered Hose Reel: Heavy-duty hydraulic in/out operation for ease of use.
  • Centralised Control Station: Integrated pressure gauge, RPM meter, and hour meter.
  • Built-in Safety Systems: Water authority-compliant header tank, Harben diaphragm protection device, and integrated pressure relief valves.

Purpose-Built for Real-World Infrastructure Challenges

While technical specifications highlight the unit’s power, its true value lies in how effectively it meets MRMS’s daily operational needs.

The trailer is purpose-built to tackle heavy sediment build up, stubborn debris, and major blockages in culverts, drainage networks, and storage tanks. By combining high pressure with high flow, operators can clear stubborn obstructions faster. Ultimately, this boosts productivity on-site while reducing the risk of costly service disruptions for utility clients.

Seamless Handover and Immediate Deployment

Following manufacture and rigorous factory testing, Flowplant delivered the trailer directly to the MRMS team in Gloucester for final commissioning.

Flowplant engineers completed thorough operational testing, custom hose installation, and comprehensive operator handovers to ensure the unit was immediately job-ready. The machine received enthusiastic feedback during its initial demonstration and entered active service right away.

Engineered Solutions for Demanding Applications

Every Flowplant system is tailored to solve real-world operational challenges. This custom Harben Century Trailer highlights how bespoke engineering, field-proven components, and customer-focused design come together to deliver long-term value.

With its powerful cleaning capabilities and rugged build, the new Harben trailer will support MRMS’s UK-wide infrastructure operations for years to come.
