CPS BLACKMAX VPBM12V vacuum pump – 340 l/min (12 CFM) for A1, A2L, A2 & A3

CPS BLACKMAX VPBM12V vacuum pump – 340 l/min (12 CFM) for A1, A2L, A2 & A3

The CPS BLACKMAX VPBM12V is the most powerful vacuum pump in the VPBM series and has been developed for demanding evacuation tasks in refrigeration, air-conditioning and heat pump technology. With a flow rate of approx. 340 l/min (12 CFM) and a final vacuum of up to 15 microns, it is particularly suitable for larger refrigeration circuits and applications where high evacuation performance is required.

The brushless, variable-speed DC motor and the intrinsically safe design allow it to be used on systems that previously utilised refrigerants in safety classes A1, A2L, A2 or A3. This makes the VPBM12V a high-performance solution for specialist contractors servicing both traditional refrigeration and air-conditioning systems and modern heat pumps and systems using flammable refrigerants.

The benefits of the CPS VPBM12V

• High flow rate: approx. 340 l/min (12 CFM)
• 2-stage design for a deep ultimate vacuum of up to 15 microns
• For systems containing residual quantities of A1, A2L, A2 and A3 refrigerants
• 1 PS / 500 W BLDC motor with variable speed
• Intrinsically safe design for modern refrigerant applications
• Universal voltage 100–240 V at 50/60 Hz
• Three connections directly on the pump: 1/4", 3/8" and 1/2" SAE
• Automatically closing solenoid valve to prevent oil backflow and vacuum loss
• Integrated analogue vacuum gauge
• Gas ballast valve to assist with moisture removal
• Large vertical oil sight glass for quick checking
• Thermal overload protection
• Operation at ambient temperatures from -15 to +55 °C

340 l/min for larger refrigeration and air-conditioning systems

With a flow rate of approx. 340 l/min (12 CFM), the VPBM12V offers the highest flow rate within the CPS BLACKMAX VPBM series. It is therefore particularly suitable for larger installations or for specialist firms where the most efficient evacuation possible is a priority in day-to-day service and installation work.

The two-stage pump design also enables a final vacuum of up to 15 microns. The VPBM12V thus combines a high free flow rate with the ability to achieve a deep vacuum.

Designed for A2L and A3 applications

The increasing use of A2L and A3 refrigerants places additional demands on the service tools used. The BLACKMAX VPBM series was developed by CPS specifically for professional HVACR applications and features a brushless motor and intrinsically safe electrical start-up components.

The VPBM12V can be used to evacuate systems in which Class A1, A2L, A2 or A3 refrigerants were previously used. The refrigerant must have been properly recovered before evacuation begins.

Three connection sizes for high flow rates

1/4", 3/8" and 1/2" SAE connections are available directly on the pump. This allows both standard service hoses and large-bore vacuum hoses to be connected without the need for unnecessary adaptors.

The evacuation setup plays a particularly important role with a high-performance vacuum pump such as the VPBM12V. Short vacuum hoses with the largest possible internal diameter reduce flow resistance and help to ensure that the pump’s high performance is actually utilised in the refrigeration circuit.

Automatic solenoid valve protects the system and the vacuum

The integrated solenoid valve is closed when de-energised and opens as soon as the vacuum pump is switched on. If the power supply is interrupted or the pump is switched off, the valve closes automatically.

This reduces the risk of vacuum pump oil being drawn back into the system and maintains the vacuum generated in the connected system.

Gas ballast valve for moisture in the system

The integrated gas ballast valve helps to remove moisture and condensable vapours from the second pump stage. This reduces the moisture load on the pump oil and helps the vacuum pump to achieve a high ultimate vacuum.

Quickly check vacuum and oil condition

The integrated analogue vacuum gauge allows the current vacuum level to be checked quickly directly on the pump. At the same time, the large vertical oil sight glass makes it easy to check the oil level and oil condition during daily operation.

Typical applications

• Larger split and multi-split air-conditioning systems
• Heat pumps and heat pump systems
• Commercial refrigeration systems
• Refrigeration and deep-freeze systems
• Installation and commissioning of new refrigeration circuits
• Servicing and repair work
• Systems using A1, A2L, A2 and A3 refrigerants

Important application note

The CPS VPBM12V is not a refrigerant extraction unit. Before evacuation, any existing refrigerant must be properly removed from the system using a suitable recovery unit. Suitability for A1, A2L, A2 and A3 refers to residual quantities remaining after refrigerant recovery has been carried out.

The VPBM12V features an ignition-proof design but is not certified as an explosion-proof unit for potentially explosive atmospheres.
