In low temperature environments (such as below -20℃), the pump assembly needs to be adapted with low viscosity hydraulic oil, and a preheating device should be added to the suction pipeline to avoid dry friction caused by insufficient lubrication inside the pump during cold start; In high temperature environments (such as above 50℃), high-temperature resistant seals (such as fluororubber) and anti-wear hydraulic oil are used to prevent increased leakage and decreased efficiency inside the pump.
