Product Description

Product Overview

The PGP620 series is a fixed-displacement cast iron gear pump belonging to the PGP 600 series of cast iron pumps. It is well-received in multiple industrial fields for its high pressure resistance, high efficiency, and flexible configuration. The following is a detailed overview based on its core attributes:

Core Structural & Design Advantages

Robust structural design features a patented interlocking two-piece cast iron structure, providing high structural stability and durability. Equipped with 12-tooth gears, bronze balance plates, and a pressure-balanced design to enhance volumetric efficiency and reduce wear under high pressure.

Low-Noise & High-Power Design

Significantly reduced system noise compared with earlier generation models. Features high power through-drive capability, allowing stable power transmission in complex hydraulic systems to meet heavy-duty operation requirements.

Flexible Combination Configuration

Supports tandem, triple, and cross-frame pump configurations. Tandem and triple pumps can share a common inlet, which simplifies integration into different hydraulic system layouts and improves overall system configuration.

Main Application Fields

Thanks to its ruggedness and excellent high-pressure performance, the PGP620 series is widely used in scenarios requiring high-duty cycles and stable hydraulic power output. Typical application areas include construction machinery, agricultural equipment, material handling equipment, and forestry machinery (e.g., cement plant equipment, fan drivers, and implement hydraulics).

Extended Configuration Options

In addition to the basic single-pump configuration, the series provides customized options such as two-section and three-section configurations. It supports clockwise, counterclockwise, and bidirectional rotation modes, and is compatible with SAE standard shafts, flanges, and port sizes to meet the personalized installation and operation requirements of OEM customers.
