Description
The DHP 0.8 Axial Piston Pump is a core high-pressure water treatment consumable tailored for industrial reverse osmosis scenarios—ideal for small and medium-sized seawater desalination, industrial wastewater desalination, and resource recovery. It specializes in transporting low-viscosity corrosive fluids like seawater and industrial saline wastewater, solving pollution and efficiency pain points in water treatment systems.


Operating on the axial piston principle, it uses the transported fluid as a lubricant, eliminating the need for a traditional oil tank and completely avoiding oil leakage—critical for water treatment’s high cleanliness demands. Weighing only 3.7 kg, its compact structure saves installation space, while the integrated flushing check valve simplifies reverse osmosis membrane system design, cutting costs.


Key components are crafted from 2205 duplex stainless steel (SAF 2205/EN 1.4462/UNS 31803), boasting excellent corrosion resistance to high-salinity media. With low vibration and noise (≤74 dB(A) per EN ISO 3744-2010), it suits environment-sensitive industrial sites. As a fixed-displacement pump, its flow rate is proportional to speed: at 3000 rpm (rated speed), flow reaches 0.81 m³/h, and motor speed can be adjusted via the formula Selected Motor Speed = (Required Flow Rate × 3000)/0.81 to match diverse system needs.


For reliable operation, strict installation and operation steps apply. During installation, distinguish the "I" (inlet) and "O" (outlet) ports, keep 3-5 mm clearance between pump and motor coupling, and use a vibration-damping base. In water treatment scenarios, install a 10 μm absolute filter at the inlet (prohibiting low-efficiency filters) to protect internal parts; add low-pressure (1 Bar) and high-pressure (70 Bar) control switches plus a safety valve to prevent idling and overpressure damage. After shutdown, flush the pump cavity with fresh water (or bactericide for long shutdowns) to avoid brine crystallization and corrosion.


Power varies with pressure: 3.0 kW at 80 Bar (ideal for seawater desalination, 70-80 Bar) and 2.2 kW below 60 Bar (suitable for low-pressure industrial desalination). It comes with a 1-year basic warranty (excluding man-made damage) and an 8000-hour maintenance-free warranty (max 18 months) under standard operation. The manufacturer, WUXI FENIGAL SCIENCE AND TECHNOLOGY CO., LTD., offers on-site maintenance and spare parts support to ensure uninterrupted water treatment.
