180B6194

The 180B6194 pump belongs to the PAHT G High Pressure Pumps series manufactured by Danfoss for hydraulic automation where compact positive-displacement units move clean fluids under high pressure. It delivers 32.00 cm³ per revolution, so each shaft turn sends a defined volume to the circuit for predictable actuator response. Operation is permitted up to 2400 rpm, which combines with the displacement to reach a maximum flow of 68.50 l/min at full speed. The rotor must not run below 1000 rpm during continuous duty to maintain lubrication and avoid flow reversal. A maximum outlet pressure of 160 barg enables the pump to feed intensifiers or direct-drive cylinders that need elevated force. The housing is machined from AISI 316, providing corrosion resistance toward aggressive process water. Fluid enters through a 1 1/4 in inlet port and exits through a 3/4 in outlet port, aligning with standard stainless-steel tube fittings.

A maximum static inlet pressure of 6.0 barg keeps the suction side within design limits, while short transients up to 20 barg are tolerated during start-up to protect the inlet check valves. The pump can operate with ambient temperatures up to 50 °C, matching the same 50 °C limit for media temperature so internal clearances remain stable. Explosion-hazard areas are addressed by the ATEX rating EX II 2 G Ex h IIC T6 Gb / EX II 2 D Ex h IIIC T150 °C Db, allowing installation in both gas and dust zones without additional enclosures. Dynamic sealing is handled by NBR elastomers that balance chemical compatibility and cost. When running at full output, the acoustic emission is 79 dBA, a level that guides enclosure design and hearing protection policies. These characteristics complete the pump’s suitability for high-pressure hydraulic systems requiring controlled inlet conditions, certified safety, and moderated noise.
