Benefits:

Black Series engineering delivers professional performance in a compact, portable package. The refined cartridge machining process creates an improved surface finish, thereby extending the pump's longevity. The expanded internal oil path creates less friction and ultimately generates less heat, thereby improving reliability during extended operation. Upgraded seals ensure maximum vacuum performance. U.S.-designed and tested for quality assurance. Easy grip handle provides comfortable portability for mobile service work. Easily removable vapour discharge/oil fill port simplifies maintenance. A large oil level sight glass with a max/min level indicator enables quick visual checks without stopping work. An easily accessible oil drain valve makes oil changes a simple process. Thermally protected motor with on/off rocker switch prevents damage during extended use. A high-volume fan provides cool air to the motor and pump, maintaining optimal operating temperatures. A check valve prevents oil backflow into the system when the pump stops. Cooling fins help maintain a cooler temperature during extended operation. The large, lightweight reinforced base provides stable positioning while remaining portable at just 6.35 kg. Durable and time-tested Mastercool quality stands up to the most gruelling conditions—offering a perfect balance of performance, portability, and value for professional technicians and serious DIY users.
