ELECTRIC REFRIGERATION OIL CHARGING PUMP R6Short Description:Features:Strong Power,Easy Charging,Strong power,easy charging under large back pressurePatent mechanism ,ensure easy charging under low temperatureConfigurate of pressure relief protection,ensure safty operationBuilt-in thermal protection device, effectively prevent overloading
R6 is a heavy-duty refrigeration oil transfer pump which is ideal for charging compressor oil into large HVAC systems. With a 3/4 HP electric motor directly coupled to a high displacement gear pump, the different viscosity oil(even the high viscosity in low temperature) can be pumped into your system even while in operation.
Built-in thermal-overload protector for effectively preventing overloaded and a ball-type check valve is installed inside of the pump to prevent oil or refrigerant from flowing back in case of a power failure or breakdown. Keep the system in safety situation. In addition, a overhead pressure gauge installed to make the easy reading the exact operation pressure. So R6 is a ultimate solution for refrigeration oil charging.
