180B1031

The 180B1031 pump belongs to the PAH Displacement Pumps series and is manufactured by Danfoss for hydraulic automation systems that demand controlled fluid delivery. Its displacement of 3.2 cm³ per revolution establishes how much hydraulic medium is transferred each shaft turn. A speed window between 1000 rpm and 3000 rpm lets the designer select flow from minimum to full capacity while keeping the pump in its safe mechanical limits. The maximum outlet pressure of 100 bar g defines the highest working pressure the circuit may reach. Peak inlet pressure is limited to 4 bar g so the supply line must be regulated to avoid overloading the inlet seals. A required torque of 6.7 N·m at maximum pressure specifies the drive motor size needed to rotate the shaft under full load. The ISO 3019-2 63A2HW mounting flange locates the pump on standard motor adapters for straightforward installation. With a weight of 4.4 kg, the unit can be handled without lifting equipment during maintenance.

The pump demands a minimum outlet pressure of 30 bar g so internal components stay lubricated and avoid cavitation during low-flow operation. A G 1/2 BSPP inlet port with 15 mm thread depth provides the suction connection, while a G 1/4 BSPP outlet port with 11 mm depth carries the pressurized discharge to downstream equipment. The housing is made from AISI 304 stainless steel to resist corrosion in aqueous or chemically aggressive media. FFKM seals are fitted to endure high temperature and chemical exposure without loss of elasticity. A shaft diameter of 15.99 ± 0.01 mm fits standard couplings, and the 62.975 ± 0.025 mm pilot diameter centers the housing accurately on the drive face. Power is transmitted through a 5 × 5 × 20 mm parallel key that locks the shaft to the prime mover. These interface dimensions, together with the previously mentioned operating limits, allow the 180B1031 to integrate predictably into hydraulic modules.
