1. Product Overview
The FG Water AXP 4.5–8.2 range is designed for high-pressure fluid delivery in seawater desalination and industrial membrane treatment systems.
The range includes five models with catalogue flows from 4.5 to 8.2 m³/h at 1,500 rpm. Each uses a fixed-displacement axial piston design and the pumped liquid as its lubricating medium.
Continuous outlet pressure up to 80 bar supports membrane applications requiring stable high-pressure feed delivery.

3. OPERATING PARAMETERS
| Parameter | Specification |
|---|---|
| Outlet Pressure Range | 10–80 bar |
| Inlet Pressure Range | 2–5 bar |
| Continuous Speed Range | 700–1,800 rpm |
| Flow Reference Speed | 1,500 rpm |
| Fluid Temperature | 2–50°C, subject to salinity limits |
| Ambient Temperature | 0–50°C |
Flow at speeds other than 1,500 rpm must be checked against the performance curve. Select the motor for the actual operating flow and pressure.
Provide suitable inlet filtration, adequate feed pressure, and overpressure protection. Flush with fresh water after high-salinity service.
4. Key Features & Benefits
