The Coolant Reservoir/Pump is an integrated component of industrial quenching systems, consisting of a storage tank for holding coolant fluid (typically water, oil, or polymer solutions) and a pumping mechanism that circulates this fluid through the system. Its primary function is to maintain consistent coolant flow and temperature during the quenching process, where heated metal parts are rapidly cooled to achieve desired material properties like hardness and strength. The reservoir provides volume capacity and temperature stabilization, while the pump ensures proper fluid circulation and pressure. This unit is designed for basic metal manufacturing environments, where it supports heat treatment operations. The reservoir is typically constructed from stainless steel (grades 304 or 316), cast iron, or polypropylene, depending on the coolant type and corrosion requirements. The pump may be made of CF8 or CF8M stainless steel for higher corrosion resistance. Key parameters include tank capacity (100–500 L), flow rate (20–120 L/min), operating pressure (1.0–1.6 MPa), motor power (0.75–7.5 kW), voltage (380–480 V AC per IEC 60038), frequency (50–60 Hz), maximum fluid temperature (60–90°C), ambient temperature (-10 to 50°C), ingress protection (IP54–IP65 per IEC 60529), and weight (150–600 kg). These values are reference ranges and must be verified for the specific model and application. The unit operates as a closed-loop system: coolant is stored in the reservoir, pumped to spray nozzles or immersion baths, contacts hot metal parts, and returns to the reservoir for cooling before recirculation. This ensures consistent quenching performance. For procurement, verify model-specific specifications, material grades, and compliance with relevant standards with the legal manufacturer or supplier.
The reservoir stores coolant at a controlled temperature, often with cooling coils or heat exchangers. When quenching is initiated, the pump draws coolant from the reservoir and circulates it through spray nozzles or immersion baths to contact hot metal parts. The heated coolant returns to the reservoir where it's cooled before recirculation, creating a closed-loop system that maintains consistent quenching performance.
