Field of application
Used as progressive, single line or dual line pump in machine groups of industrial machines as well as in medium-sized and large construction & mining machines.
The barrel pump BEKA Stream E is driven by a brushless DC motor. The rotary motion of the motor is transformed into a stroke movement of the piston rod by an eccentric in the housing.
The delivery piston of the pump is firmly connected to the piston rod, which triggers a suction and pressure stroke. Hence, the lubricant is sucked in at the suction bore at the lower end of the delivery pipe and is delivered to the pressure outlet.
The integrated return connection at the pump can be used to lead lubricant after pressure relief processes and from pressure limiting valves directly back into the lubricant barrel via the pump pipe. Thus, additional bore holes in the cover and follower plate are redundant
