Gear oil pump 1PF2G3 Series 1PF2G3-3X/020LN07MHL

ℹ️ Product Description

The Gear oil pump 1PF2G3 Series 1PF2G3-3X/020LN07MHL from Hengmeisi is a compact, high-efficiency external gear pump with 94% volumetric efficiency, low pulsation and noise. Rated for 250 bar continuous (300 bar peak), it’s ideal for tight spaces. In addition, Hengmeisi provides Rexroth-standard gear pumps.

✅ Key Advantages

Low-Pulsation, Low-Noise OperationUnlike traditional gear pumps, the 1PF2G3-3X/020LN07MHL uses precision-ground helical gears to reduce flow pulsation by 30%, resulting in quieter, smoother operation. This makes it perfect for noise-sensitive industrial environments.

Hydrostatic Gap Compensation for LongevityThe pump’s built-in pressure-compensated plate automatically adjusts clearances to maintain efficiency over time, eliminating common wear issues in standard gear pumps. This extends service life to over 10,000 hours.

Compact, Robust Design for VersatilityWith a compact housing and universal mounting flange, the 1PF2G3-3X/020LN07MHL fits seamlessly into tight machinery spaces, while its cast iron body withstands harsh industrial conditions and pressure spikes.

Wide Compatibility with Hydraulic FluidsEquipped with high-temperature seals, this pump works reliably with mineral oils and biodegradable fluids, supporting temperatures from -20°C to +80°C.

📌 Model Code Breakdown

The 1PF2G3-3X/020LN07MHL features a straightforward coding system, making it easy to identify key specifications without specialized hydraulic expertise:

1PF2G3: External gear pump series, G3 frame size, designed for medium-pressure applications

3X: Third-generation design, upgraded for improved wear resistance and efficiency

020: Nominal displacement of 20 cm³/rev, ideal for medium-flow hydraulic circuits

LN: Left-hand rotation (standard for most industrial applications)

07: 7-tooth gear configuration, optimized for balanced flow and low pulsation

MHL: Metric mounting flange, high-pressure seal variant, suitable for continuous heavy-duty use

As the core model in the 1PF2G3 series, the 1PF2G3-3X/020LN07MHL is widely trusted in industrial machinery, mobile hydraulics, and material handling systems.
