What is a Gear Oil Pump GSP2 Series GSP2-AOS16AR-AO?

The Gear Oil Pump GSP2 Series GSP2-AOS16AR-AO is a high-precision external gear pump series designed for medium-high pressure, continuous-duty hydraulic systems, featuring lightweight structure, low energy consumption and strong environmental adaptability. GSP2-AOS16AR-AO, as the core model of the series, is optimized for small and medium-sized hydraulic systems, with outstanding precision, low noise and easy maintenance, winning wide recognition from customers in Europe, Asia and Africa for its reliable quality and personalized customization capacity.

GSP2 Series Overview

The Gear Oil Pump GSP2 Series GSP2-AOS16AR-AO is a new generation of high-precision external gear pump series independently developed and improved by our company, which is different from traditional heavy-duty gear pumps. It is mainly positioned for medium-high pressure (rated pressure 210bar, peak pressure 250bar) hydraulic systems, with the characteristics of compact structure, lightweight design, low noise and high volumetric efficiency. The series adopts optimized gear profile design and advanced processing technology, which effectively reduces internal leakage and energy loss, and is widely applicable to various small and medium-sized hydraulic systems that require high precision and stable operation. Unlike other series, the GSP2 series focuses on "precision and energy saving", and supports flexible configuration combination, which can be customized according to the specific working conditions of customers, such as different bearing types, sealing materials and connection methods, to meet the personalized needs of different industries.

Core Model: GSP2-AOS16AR-AO Detailed Introduction

As the core model of the GSP2 series, GSP2-AOS16AR-AO inherits all the advantages of the series and has been optimized for targeted application scenarios, becoming the preferred choice for small and medium-sized hydraulic systems. The model code GSP2-AOS16AR-AO has clear implications: GSP2 represents the series model, AOS indicates the integrated oil port design, 16 refers to the displacement of 16 cm³/rev, AR stands for the standard flange connection, and AO denotes the high-temperature resistant sealing configuration. This model is specially designed for equipment with limited installation space and high precision requirements, with a compact structure and lightweight design (net weight only 2.8kg), which is very convenient for installation and maintenance, and can be perfectly adapted to narrow installation environments such as small hydraulic stations and precision machine tools.

Structure, Material & Craft Advantages

Different from the traditional cast iron structure, Gear Oil Pump GSP2 Series GSP2-AOS16AR-AO adopts high-strength aluminum alloy pump body and end cover, which not only reduces the overall weight by 30% compared with similar products, but also has better heat dissipation performance, ensuring stable operation even in high-temperature working environments (operating temperature range -15℃～+90℃). The gear components are made of high-quality alloy steel, processed by precision (honing) and carburizing heat treatment, which greatly improves the surface finish and hardness of the gears, enhances the wear resistance and service life, and effectively reduces internal leakage. The built-in sealing components adopt imported high-temperature resistant lip seals, which can effectively prevent oil leakage, adapt to a variety of mineral hydraulic oils and synthetic hydraulic oils, and maintain good sealing performance under long-term continuous operation. In addition, the pump adopts a integrated oil port design, which simplifies the pipeline connection, reduces the installation space, and improves the overall reliability of the hydraulic system.

Performance Parameters & Core Advantages

In terms of working performance, GSP2-AOS16AR-AO has obvious advantages in precision, stability and energy saving. Its rated displacement is 16 cm³/rev, rated pressure is 210bar, peak pressure can reach 250bar, and volumetric efficiency is up to 92%, which is 2-3% higher than that of ordinary gear pumps of the same specification. The model adopts optimized 10-tooth gear design, which effectively reduces flow pulsation and operation noise, with the noise level as low as 62dB (1m away), creating a quieter working environment. Unlike the sliding bearing design of traditional pumps, GSP2-AOS16AR-AO adopts high-precision needle roller bearings, which can bear higher radial load, improve the operation stability of the pump, and extend the service life to 10000 hours, which is far higher than the industry average level. In addition, the pump has good self-priming performance, with a self-priming height of up to 0.8m, which can effectively avoid dry operation and reduce the failure rate.

Application Scenarios & Versatility

GSP2-AOS16AR-AO, with its compact structure, high precision and stable performance, is widely used in various small and medium-sized hydraulic systems. It is especially suitable for precision machine tools, small hydraulic stations, automation equipment, light industry machinery (such as packaging machinery, printing machinery), agricultural machinery (such as small harvesters, garden machinery) and other fields, providing stable and reliable power support for the hydraulic system. The model has strong compatibility and interchangeability, which can be directly replaced with the original model of the same specification, without modifying the pipeline and installation structure, greatly reducing the replacement cost and time. At the same time, it supports multi-pump parallel combination, which can be combined with other GSP2 series models to form a multi-circuit hydraulic system, meeting the needs of complex working conditions.
