The Dongfeng 8-sided integrated tank cleaning and suction truck uses a water circulation pump that operates with water as the working fluid. During operation, the water serves as a coolant, enabling prolonged use without damaging the pump. However, since water circulation pumps are typically paired with an engine unit, the purchase cost is relatively higher. Because water can easily freeze, special attention must be paid to anti-freeze measures in winter or cold regions—water in the tank must be drained after work each afternoon. The vacuum pump (vane-type vacuum pump) primarily relies on rotating vanes and uses oil as the working fluid. Due to the high-speed rotation of the vanes, the pump interior can quickly overheat. Therefore, after emptying one tank, it’s necessary to pause briefly to allow the pump to cool down, preventing overheating that could damage or burn the internal vanes.
