Feed pump , Iran

The Komatsu 155 gear pump is a critical component in the hydraulic systems of bulldozers and excavators from this manufacturer. This pump delivers a nominal flow rate of approximately 180 liters per minute at an engine speed of 1900 RPM. The maximum working pressure of this pump is designed to reach 280 kilograms per square centimeter, equivalent to about 270 bars. The pump body is manufactured using an extrusion method with high-pressure pressing, resulting in a smooth surface and high material density. The internal gears of this pump are made from alloy steel with heat treatment reaching 58 HRC for superior wear resistance against tooth surfaces. The number of teeth on each gear typically ranges from 10 to 14 with a module between 3 and 5 millimeters. Precision ground gear profiles ensure volumetric efficiency above 90 percent even after extended operating hours.

The Komatsu 155 gear pump is widely used in bulldozer models D155A, D155C, and D355A along with S6D125 and S6D155 engines. This pump is available in a three-stage configuration capable of supplying hydraulic flow to three independent circuits simultaneously. Using high-quality bushings and high-temperature grade O-ring seals significantly extends pump service life and reduces failure rates. Installation of this pump is direct without requiring any modifications to the existing hydraulic circuit layout. The recommended hydraulic oil viscosity for this pump ranges from 32 to 68 centistokes at 40 degrees Celsius. Maximum allowable operating temperature for this pump is 90 degrees Celsius to prevent oil degradation and seal damage. Regular maintenance intervals for this pump are set at every 2000 operating hours for optimal performance.You can order and buy Feed pump from Iran by contacting us through whatsaap and email.
