BEKA Hamax

Hydraulic breakers are highly-stressed add-on tools for construction machines and need to be supplied with special lubricants to reduce wear and tear of the chisel. The HAMAX range offers a lubrication system for hydraulic breakers or other construction machinery attachments. They are designed to mount directly on the attachment, compact but made of sturdy material to resist the many forces they have to endure.

General

The HAMAX-2 pumps are designed to work with different grease cartridges for EP-greases up to NLGI-2, even with high solid additives like copper. All HAMAX cartridge pumps are equipped with a type S cartridge connection thread as a standard. Other cartridge types can be used with a corresponding adapter. Due to the cartridge concept, replacing the cartridge when it’s empty will be a quick, easy and clean task. A grease zerk is integrated in the pump housing for manual lubrication in case of a failure of the hydraulic system.

The HAMAX-2 pumps have an output of 0.12 cm3/stroke, which is adjustable to suit the individual requirement of the lubrications points. When a higher output is requested, we offer the HAMAX-11 with a delivery rate of 0.25 up to 1 cm3/stroke. The output can be adjusted via an adjustment screw on the pump.

The HAMAX-11 is equipped with a refillable reservoir of 0.1, 0.2 or 0.4 liter. The HAMAX 11 is designed that with each hydraulic pulse one lubricant stroke is carried out. The delivery rate is adjustable with a setscrew. Three different types of reservoir sizes are available. The grease level control is carried out visually by the level indicator pin.
