Product Description

The DHP 1.0 axial piston pump, a ultra-compact water treatment consumable from WUXI FENIGAL, is tailored for small/medium industrial reverse osmosis systems—ideal for small island seawater desalination and workshop-level industrial wastewater desalination. It solves "efficient transportation + low pollution" needs of small systems, becoming a reliable fluid transfer solution for miniaturized 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). It uses the transported fluid as lubricant, eliminating oil tanks and oil leakage to meet strict cleanliness demands. Weighing only 3.7 kg with an integrated flushing check valve, it simplifies RO membrane piping, reducing installation space and costs.

Core Advantages for Water Treatment

  • Corrosion Resistance & High Stability: Key components use 2205 duplex stainless steel for high-salinity resistance; 80 Bar continuous working pressure meets RO system high-pressure needs.
  • Flexible Flow & Ultra-Low Noise: Fixed-displacement design—flow is proportional to speed (0.92 m³/h at 3000 rpm, adjustable for different systems). ≤74 dB(A) noise (per EN ISO 3744-2010), fitting quiet workspaces.

Installation & Operation Tips

  1. Interface Connection: "I" = inlet, "O" = outlet (both G1/2〞, 13 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 (idling >10 mins ruins plungers); 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).
