Why Black Knight
12 CFM.
Sparkless A2L-safe.
15-micron deep.
The HCPRO Black Knight HCBK-12DC is the flagship sparkless vacuum pump — 12 CFM high-capacity displacement, 15-micron lab-grade ultimate vacuum, and a brushless DC motor that produces no sparks for safe evacuation of A2L and flammable refrigerants. The pump built for the A2L transition and high-volume commercial service.
Sparkless BLDC motor, A2L-safe
The brushless DC (BLDC) motor has no brushes and produces no sparks — eliminating the ignition risk that makes standard induction-motor pumps dangerous on A2L and flammable refrigerant systems. As the industry shifts to R-32, R-454B, and hydrocarbon refrigerants, a sparkless pump isn't a luxury — it's the safe-practice requirement. The HCBK-12DC is the Black Knight pump built for that future.
12 CFM, 15-micron lab-grade vacuum
12 CFM free air displacement — double a 6 CFM pump — pulls large commercial systems, long line sets, and multi-evaporator setups down fast. And it goes deep: 15-micron ultimate vacuum, lab-grade, far below the 500-micron clean threshold. High torque from the BLDC motor maintains pull-down speed even as the vacuum deepens.
Universal voltage, gas ballast
Universal voltage 100-240V, 50/60Hz — auto-adapts to any service power worldwide, no switching. The gas-ballast valve purges moisture from the oil during wet-system evacuation. 20.5 oz / 600 mL oil capacity for sustained commercial-volume work. The no-mess quick drain lets you change oil hot — no cool-down wait — and a large sight glass rounds out the flagship build.

Common questions
Answers from the warehouse floor.
Still stuck? Call our techs at 305-720-0044.
Does HCPRO warranty the products?
Yes — every HCPRO Black Knight product ships with a 1-year limited warranty against manufacturing defects under normal professional use. See our full warranty terms.
Which Black Knight vacuum pump should I pick?
HCEC-6S (6 CFM single-stage, 115V) is the economy choice for residential service. HCBK-6D (this pump — 6 CFM dual-stage, dual-voltage) is the workhorse for techs who want deeper vacuum and global voltage. HCBK-12DC (12 CFM sparkless BLDC, 15 micron) is the flagship for commercial volume and A2L / flammable refrigerant work.
Why do I need a sparkless pump for A2L refrigerants?
A2L refrigerants (R-32, R-454B) and A3 hydrocarbons (R-290, R-600) are flammable. A standard induction-motor vacuum pump generates electrical sparks at the motor brushes/commutator — an ignition source if flammable refrigerant vapor is present during evacuation. The HCBK-12DC's brushless DC (BLDC) motor has no brushes and produces no sparks, eliminating that ignition risk. As the industry transitions to A2L, sparkless evacuation is becoming standard safe practice.
What makes 12 CFM and 15 microns worth the premium?
Two things: speed and depth. 12 CFM moves double the air of a 6 CFM pump — critical on large commercial systems, long line sets, and multi-evaporator setups where a smaller pump takes forever. And 15-micron ultimate vacuum is lab-grade deep — far below the 500-micron clean threshold — which matters for moisture-sensitive systems and high-end commercial work. Plus the sparkless BLDC motor future-proofs you for A2L.
What oil does it use and how often do I change it?
Use ISO VG46 synthetic vacuum pump oil (we sell it in quart and gallon). The HCBK-6D holds 13.9 oz / 410 mL. Change the oil when it turns cloudy or milky (moisture contamination), after every heavily-contaminated system, or at minimum every 10-20 evacuations. Clean oil is the single biggest factor in how deep your pump pulls — the no-mess drain makes field changes quick.
Do I need a special hose for fast evacuation?
For fastest pull-down, use a 3/8″ high-flow evacuation hose (the Black Knight Dual Force 3/8″ hose) rather than a standard 1/4″ charging hose. The larger bore moves significantly more air per minute. The HCBK-6D has both 1/4″ and 3/8″ SAE intake fittings so you can run either. Pair with the Dual Force evacuation kit for the matched-spec setup.
Can I use this on standard R-410A systems too?
Absolutely. The HCBK-12DC handles standard HFC refrigerants (R-410A, R-22, R-134a, R-404A) just as well as A2L — the sparkless motor and 12 CFM / 15-micron performance are advantages on any system. It's the one pump that covers everything from residential R-410A to commercial A2L to flammable hydrocarbon work. If you only service residential HFC and want to save, the HCEC-6S or HCBK-6D are more economical.
Can I return an unused pump?
Yes — free returns within 30 days for unused pumps in original packaging with no oil added. Once oil has been added and the pump run, it's considered used. Read our full return policy.
Do you offer fleet pricing on pumps?
Yes — trade pricing on this page, plus volume discounts for shops outfitting multiple service trucks. Email hcproproductsusa@gmail.com with your model mix and quantities and we'll send a custom quote within 24 hours.
