Is the Gear Pump Ø25.4 mm Plate, Left Rotation, Threaded Ports, TRALE compatible with hydraulic oil other than L-HM45?

Gear Pump Ø25.4 mm Plate, Left Rotation, Threaded Ports, TRALE is optimized for hydraulic oil type L-HM45 or equivalent and supports a wide viscosity range from 10 to 600 cSt (recommended 30–45 cSt). Therefore it can be used with other hydraulic oils provided they are equivalent to L-HM45 in specification (mineral-based anti-wear hydraulic oils meeting similar standards) and their viscosity and temperature characteristics fall within the stated operating window. Ensure the oil’s viscosity at operating temperature is within 10–600 cSt (ideally 30–45 cSt), and that fluid properties (anti-wear additives, compatibility with NBR seals, oxidation stability and cleanliness) match hydraulic requirements. Avoid fluids with additives or base stocks incompatible with NBR seals (e.g., certain synthetics, phosphate esters) unless manufacturer confirmation is obtained. When in doubt, consult the pump manufacturer or supply documentation for approved oil equivalents.

Can the Gear Pump Ø25.4 mm Plate, Left Rotation, Threaded Ports, TRALE be used in systems operating continuously at temperatures above +90°C?

No. The Gear Pump Ø25.4 mm Plate, Left Rotation, Threaded Ports, TRALE is specified for continuous operation in medium temperatures up to +90°C. Systems operating continuously above +90°C exceed the pump’s declared maximum operating medium temperature and thus are outside its rated specification; using it continuously above +90°C risks seal degradation, loss of performance and premature failure. For reliable continuous operation at temperatures above +90°C, select a pump rated for higher temperatures or consult the manufacturer for suitable materials and adaptations.
