Description de produit

The DHP 2.1 axial piston pump, a compact and efficient water treatment consumable, is tailored for small/medium seawater & industrial desalination systems—ideal for island desalination equipment and factory wastewater desalination devices. Developed by WUXI FENIGAL, it excels in high-pressure stability, strong corrosion resistance, and space-saving design, becoming a reliable fluid transfer solution for small-scale desalination projects.


Operating on the axial piston principle, its plungers (parallel to the drive shaft) reciprocate in bores to adjust pump cavity volume, enabling high-pressure transfer of low-viscosity corrosive media (seawater, industrial saline wastewater). Unlike traditional pumps, it uses the transported fluid as lubricant, eliminating oil tanks and oil leakage to meet desalination’s strict cleanliness demands. Weighing only 7.8 kg with an integrated flushing check valve, it simplifies RO membrane system design, reducing installation space and costs.

Core Advantages for Water Treatment

  • High-Pressure Stability & Low Interference: 80 Bar continuous working pressure meets RO system needs; ultra-low pulse, ≤77 dB(A) noise (per EN ISO 3744-2010), fitting environment-sensitive industrial sites.
  • Corrosion Resistance & Flexible Flow: Key components use 2205 duplex stainless steel for high-salinity resistance; 3000 rpm rated speed delivers 2.1 m³/h flow, with adjustable motor speed to match different system demands.

Installation & Operation Tips

  1. Interface Connection: "I" = inlet, "O" = outlet (both G3/4〞, 18 mm). Strictly avoid reverse connection to prevent plunger/check valve damage.
  2. Filtration Requirement: Install 10 μm absolute filter (≥99.98% efficiency, β10>5000) at inlet—prohibit 90% efficiency filters to avoid plunger wear.
  3. Pressure Protection: Inlet low-pressure switch (1 Bar) prevents dry running; outlet high-pressure switch (70 Bar) + safety valve (5-9 MPa) protects RO membranes/pipelines.
  4. Start-Up/Shutdown: Flush with fresh water after shutdown (add bactericide if >15 days shutdown). Never start with rear valve closed.

Maintenance & Warranty

  • Daily Maintenance: Check filter pressure difference (replace element if >0.5 Bar) to keep inlet fluid clean.
  • Regular Inspection: Full inspection every 8000 hours (check shaft seal leakage, plunger wear—replace parts if flow drops >10%).
  • Warranty: 1-year free maintenance (delivery date); 8000-hour maintenance-free warranty (if operated as required, max 18 months).
