Pumpensicherheitsblock DBAWR40AH2N1X/315S6SMG24N9K4B12 - Bosch Rexroth R900937540

The high-pressure flange takes the forces at the pump outlet directly, so no subplate is required. Setting runs between 3.7 and 315 bar on the internal hexagon under the protective cap. A built-on directional seat valve handles unloading while the pressure stage itself works pilot-operated in poppet seat design, discharging up to 450 l/min.

Benefits

• Setting range of 3.7 to 315 bar on the internal hexagon under the protective cap
• Solenoid unloading through a built-on directional seat valve
• High-pressure flange instead of subplate mounting, size 40
• Flow up to 450 l/min, maximum operating pressure of 350 bar
• Pilot-operated pressure stage in poppet seat design with limited leakage
• NBR seals for HL hydraulic fluid, 24 VDC, mass 14.82 kg

Application

The block sits at the outlet of large power units and covers protection and unloading in a single part. Between two working strokes the pump circulates without pressure, which cuts lost power and keeps the oil cooler. A setting range reaching 315 bar covers presses and clamping systems alike.

Manufacturer

Bosch Rexroth lists this pump safety block DBAWR40AH2N1X/315S6SMG24N9K4B12 under material number R900937540. The mating face for the high-pressure flange has to be machined to suit, a subplate will not replace it.
