What is the maximum continuous operating pressure for the Gear displacement pump, Ã50.8 mm plate, left direction of rotation, threaded connections, TRALE when using L-HM45 oil?

Gear displacement pump, Ã50.8 mm plate, left direction of rotation, threaded connections, TRALE . maximum continuous operating pressure with L-HM45 oil is the stated maximum operating pressure for the model (continuous operation). Based on the product description, use the pump at or below its specified continuous operating pressure; do not exceed that value for continuous service.

Q: Can the Gear displacement pump, Ã50.8 mm plate, left direction of rotation, threaded connections, TRALE operate continuously at -20Â°C with L-HM45 oil?

Yes. Gear displacement pump, Ã50.8 mm plate, left direction of rotation, threaded connections, TRALE can operate continuously at â20Â°C with L-HM45 oil. The pumpâs specifications list medium operating temperature from â20Â°C to +90Â°C, permit L-HM45 as the hydraulic fluid, and allow viscosities from 10 to 600 cSt (recommended 30â45 cSt). Ensure the oil viscosity at â20Â°C remains within the acceptable range and that NBR seals are suitable for repeated low-temperature cycling; if viscosity is too high at â20Â°C, warm-up or use of lowâtemperature grade oil/additives may be required.

Q: Does Gear displacement pump, Ã50.8 mm plate, left direction of rotation, threaded connections, TRALE require special seals for fluids other than L-HM45?

No. Gear displacement pump, Ã50.8 mm plate, left direction of rotation, threaded connections, TRALE is specified with NBR seals and designed for hydraulic oil type L-HM45 or equivalent. NBR compatibility covers a range of mineral hydraulic oils and the specified viscosity (10â600 cSt, recommended 30â45) and temperature range (medium -20Â°C to +90Â°C). For fluids chemically different from L-HM45 (e.g., synthetic esters, water-glycol, phosphate esters, biodegradable fluids, or aggressive solvents), NBR may not provide adequate chemical or thermal resistance. In such cases special seals (e.g., FKM/Viton, HNBR, EPDM, PTFE) compatible with the specific fluid and operating temperature must be used. Therefore: if you intend to run standard mineral hydraulic oils or true equivalents to L-HM45, no special seals are required; for other fluid types, select seals rated for that fluid and confirm with the pump manufacturer.
