MPGB001HTYZ4DEOFS1AZPF12011K1NN

The MPGB001HTYZ4DEOFS1AZPF12011K1NN unit is produced by Bosch Rexroth for the MPGB-AZPF Close-Coupled Motor Pumps series. It supplies hydraulic automation circuits with continuous flow by combining a gear pump and an electric motor in one assembly. The motor uses a totally enclosed fan-cooled enclosure that shields internal windings from dust while an external fan moves cooling air over the frame. Its 1 hp rating defines the electrical load needed to reach design performance, and the 145TYZ frame lets installers align the shaft on standard pump bases. A four-pole winding sets synchronous speed close to 1,800 rpm on 60 Hz mains, yet the shaft actually turns at 1,750 rpm under rated load, or 1,450 rpm when fed from 50 Hz power. Pump displacement is 0.67 in³ per revolution, so each turn moves a fixed volume of fluid that scales linearly with speed. At rated speed the assembly delivers 5.2 gpm (19.8 L/min), sufficient for light machine tools and clamp circuits.

System pressure capability reaches 380 psi (26 bar) at the full flow listed above, giving users reserve force for moderate-duty cylinders and rotary actuators. Pressure fluid exits through an SAE-10 port, and the 7/8-14 UNF-2B internal thread supports common O-ring boss fittings that maintain a leak-free joint under vibration. Inlet oil enters through a downward-facing suction port that simplifies priming when the reservoir is below the pump centerline; this connection follows the larger SAE-12 size to minimize velocity and reduce cavitation risk. The suction interface is machined with a 1-1/16-12 UN-2B thread so standard straight-thread adapters can be fitted without special tooling. These hydraulic interfaces, combined with the previously noted flow and speed data, allow the pump to integrate quickly into compact power units where floor space is limited. Together, the pressure rating, port geometry, and thread forms define the limits for safe operation and ensure predictable performance in automated clamping, indexing, and small press circuits.
