The pumps are designed to work with specific types of hydraulic fluids. The recommended hydraulic fluid should have appropriate viscosity, anti – wear, and anti – oxidation properties. The suitable viscosity range of the hydraulic fluid is generally between 10 – 400 cSt (centistokes) at the operating temperature range of the pumps, which is typically from – 20°C to + 80°C (- 4°F to 176°F).
