The DYNASET HPW520 remains one of the most utilised tools in ROV operations, valued for its versatility and effectiveness across a wide range of subsea tasks.
Recognising its critical role, J1W Ltd has spent the past two years engineering a custom designed Wandfluh control block purpose-built for the HPW520 Sub Jetting System — a compact, high-performance subsea HP pumping and jetting solution.
This control block is the result of rigorous testing to meet the real-world demands of subsea environments. The outcome: a highly durable, precision-engineered solution that enhances the reliability and performance of one of the most essential ROV tools.
Key advantages of the J1W control block:
– Eliminates the need for multiple adaptors and external pipework — reducing both cost and potential leak paths.
– Fitted with stainless steel, corrosion-resistant cartridges for long-lasting subsea performance.
– Pilot on/off valve remains stable and functional regardless of upstream pressure changes.
– Input-side flow control allows accurate metering and smooth pump operation — preventing overrevving and protecting the HPW520 pump.
– Input pressure control delivers smoother pump startup and consistent output pressure.
– Designed for low maintenance, simple setup, and easy diagnostics via integrated gauge port.
Powering the system is the DYNASET SUB version HPW pump, engineered specifically for saltwater subsea use. Compared to traditional marine versions, it offers:
– Improved resistance to internal corrosion and seal failure
– Simplified flushing process for better long-term reliability
– Less maintenance with significantly extended service life
Matched with a performance-optimised lance nozzle, the system delivers unmatched cleaning efficiency and reliability subsea.
