Cast Iron Hydraulic Gear Motor PGM20 For Agricultural Machinery
Hydraulic Gear Motor Introduction
The PGM20 series hydraulic gear motors are cast iron fixed displacement gear motors designed for low- to medium-pressure mobile machinery and industrial applications, renowned for their exceptional reliability and economy.These motors feature a heavy-duty cast iron housing and precision needle roller bearing construction, ensuring stable operation over extended periods under harsh conditions. Their core strengths lie in their excellent volumetric efficiency (typically exceeding 90%) and low internal leakage design, maintaining high-efficiency output even under high loads and significantly reducing system energy consumption. Simultaneously, optimized gear meshing and bearing arrangement achieve low-noise, low-vibration operation, making them ideal for noise-sensitive equipment such as agricultural machinery, material handling vehicles, and small engineering vehicles.
Runhe Hydraulics' PGM series hydraulic gear motors are high-performance external meshing fixed displacement motors, available in 020/050/300/500/600 series, 100% compatible with Parker, featuring high efficiency, low noise, compact size, high power density, strong durability, 1-year warranty, and excellent after-sales service.
Hebei Runhe Hydraulic Machinery Co., LTD. is a leading manufacturer specializing in hydraulic system solutions. We are also one of the most recognized suppliers of large OEM equipment manufacturers in the domestic hydraulic industry. "Survival by quality, development by integrity" is our business philosophy, we are willing to achieve a win-win situation with friends all over the world!
