125 Series 4-Port Motor

Product catalog summary

Specifications:
The document describes a range of fixed displacement motors with displacements from 120 in³ to 250 in³. These motors are 4-port double motors providing 2-speed operation with external valving. They offer starting and stall torques equal to 90-94% of theoretical torque and can operate continuously at speeds up to 350 RPM and power up to 300 HP. The motors have a compact design with a 10-inch diameter and 23-inch length, weighing 380 lbs.

Features:
The 125 Series 4-Port Motor operates at a standard pressure of 3000 PSI (Code 61). It features a vane crossing vane design for higher volumetric and mechanical efficiencies. The motor is designed for high reliability and efficiency with a pressure-balanced rotating group, reducing cross port leakage.

Performance Data:
Performance charts indicate flow and torque characteristics at various pressures and speeds. The motor's design allows for more power strokes per revolution, enhancing mechanical efficiency and providing flatter torque curves.

Bearing and Load Information:
The bearings can handle radial loads as per the provided charts, but thrust loading is not recommended for the standard motor. Thrust-capable motors have specific charts for thrust and radial load capacities. The document advises consulting an engineer for applications exceeding 300 HP.

Configuration and Operation:
The motor can rotate in either direction and is unrestricted in mounting position. It requires an external case drain, and the case pressure should be less than 35 PSI. The motor can be configured for two-speed operation using external valving, with specific recommendations for series/parallel and logic circuits.

Fluid and Filtration:
Recommended fluids should contain rust, oxidation, and foam inhibitors, with viscosity maintained between 100 and 200 SUS. Fluid temperature should not exceed 180°F. Filtration should be at least 25 microns.

Warranty:
Rineer Hydraulics, Inc. offers a limited warranty for defects in material and workmanship, valid for 455 days from shipment or one year from first use. The warranty excludes consequential damages and is void if the product is dismantled or used beyond its capabilities.

Model Code and Options:
The document provides a model code breakdown for specifying motor series, port options, rotary group designation, shaft options, bearing package, seal package, and displacement options.
