CPS VPB6D Black Max vacuum pump – spark-proof for A1, A2L, A3 and NH3 Product description The CPS VPB6D Black Max vacuum pump is a two-stage, spark-proof vacuum pump for professional use in refrigeration and air-conditioning technology. It is suitable for work on refrigerant systems using A1, A2, A2L and A3 refrigerants as well as NH3 / R717, in accordance with the manufacturer’s specifications. With a free suction volume of 151 l/min at 50 Hz , a final vacuum of up to 0.033 mbar and a powerful 1/2 PS motor, the VPB6D is designed for fast and reliable evacuation. Thanks to its two-stage design, the pump achieves a high vacuum, making it ideal for the commissioning, maintenance and repair of refrigeration, air-conditioning and heat pump systems. Your benefits Spark-proof design for modern refrigerant applications Suitable for A1, A2, A2L, A3 and NH3/R717 in accordance with the manufacturer’s specifications Two-stage vacuum pump for high ultimate vacuum 151 l/min free intake volume at 50 Hz Final vacuum down to 0.033 mbar Integrated solenoid valve to prevent backflow in the event of a power failure Gas ballast valve for improved performance in more humid systems Dual-voltage motor for 115 V and 230 V Double-sealed sight glass made of real glass Easily accessible oil drain for simple maintenance Robust Black-Max design for daily service use For service, maintenance and commissioning The CPS VPB6D has been developed for specialist refrigeration companies that regularly evacuate refrigeration, air-conditioning and heat pump systems. Thanks to its high suction capacity and two-stage design, the pump is suitable for both new installations and service work, repairs and the replacement of components. A suitable pump is crucial, particularly when working with modern refrigerants such as R32, R1234yf, R454C, R290 or R600a . The spark-proof design facilitates the professional and safe handling of the relevant refrigerant classes. Integrated solenoid valve The integrated solenoid valve prevents air from flowing back into the evacuated system in the event of a power cut or when the pump is switched off . This helps to maintain the vacuum achieved more effectively and reduces the risk of the system becoming contaminated again. Gas ballast valve for improved evacuation The gas ballast valve aids start-up and evacuation, particularly when moisture is present in the system or when operating at lower ambient temperatures . This allows the pump to operate more efficiently and achieve a deep vacuum more reliably. Typical applications Evacuation of refrigeration systems Servicing of air-conditioning systems Maintenance and commissioning of heat pumps Work with A2L refrigerants such as R32 and R1234yf Work with A3 refrigerants such as R290 and R600a NH3/ammonia systems in accordance with manufacturer’s approval Customer service, workshop and installation call-outs Note on use When using flammable refrigerants and NH3, the applicable safety regulations, manufacturer’s specifications and legal requirements must be observed. The pump should only be used by qualified specialist personnel. Before use, check that the refrigerant, system, oil, connections and working environment are suitable for the application. Why choose the CPS VPB6D Black Max? The CPS VPB6D is the ideal choice when a robust, high-performance and spark-proof vacuum pump is required for modern refrigerants. The combination of two-stage pumping technology, high suction capacity, a solenoid valve, gas ballast and low weight makes it particularly well-suited for professional refrigeration and air-conditioning servicing. The CPS VPB6D Black Max vacuum pump is a two-stage, spark-proof vacuum pump for A1, A2, A2L, A3 and NH₃ refrigerants. With a flow rate of 151 l/min, a final vacuum of 0.033 mbar, a 1/2 PS motor, a solenoid valve, a gas ballast valve and a weight of 11 kg, it is ideally suited for evacuation, servicing and commissioning in refrigeration and air-conditioning systems.
