What fluids and viscosity range are recommended for the Gear Pump Ø36.5 mm Plate, Right Rotation, Threaded Ports, TRALE?

Gear Pump Ø36.5 mm Plate, Right Rotation, Threaded Ports, TRALE is designed to operate with hydraulic oil type L-HM45 or equivalent. Recommended fluid viscosity range: 10–600 cSt, with the optimal viscosity specified as 30–45 cSt. Operating temperature range for the medium: -20°C to +90°C.

Can the Gear Pump Ø36.5 mm Plate, Right Rotation, Threaded Ports, TRALE be used with fluids other than hydraulic oil L-HM45, such as biodegradable or fire-resistant fluids?

Gear Pump Ø36.5 mm Plate, Right Rotation, Threaded Ports, TRALE is specified for hydraulic oil type L-HM45 or equivalent and uses NBR seals. It supports viscosities 10–600 cSt (optimal 30–45 cSt) and temperatures -20°C to +90°C (medium). Use with other fluids (biodegradable or fire‑resistant) is possible only if those fluids meet the pump’s viscosity, temperature and material-compatibility requirements. Key considerations: - Viscosity: fluid must fall within 10–600 cSt at operating temperature (ideally 30–45 cSt). - Seal and elastomer compatibility: NBR may be degraded by many synthetic, phosphate‑ester (fire‑resistant) or certain biodegradable fluids; verify chemical compatibility with NBR. - Lubricity and additives: some fire‑resistant or low‑lubricity fluids increase wear risk for gears and bearings. - Operating temperature and pressure: fluid’s thermal properties must suit the pump’s specified ranges and maximum working pressure. Recommendation: consult fluid manufacturer for NBR compatibility and lubricant-equivalence, and perform manufacturer approval or field testing before using biodegradable or fire‑resistant fluids in Gear Pump Ø36.5 mm Plate, Right Rotation, Threaded Ports, TRALE.
