Enterprise Products

LQCZ/ZP/ZE Series Heavy-Duty Chemical Process Pumps

The LQCZ/ZP/ZE series petrochemical process pumps are strictly designed in accordance with the API 610​ standard, specifically engineered for continuous operation in the petrochemical and process industries. The products are suitable for transferring clean or particle-containing media, covering a wide range of complex conditions from low temperature to high temperature, and for neutral or corrosive liquids, offering excellent system adaptability and operational reliability.

This pump series adopts an OH1/OH2​ structural design with axial suction and radial discharge, ensuring stable operation. Excellent hydraulic balance is achieved through wear rings and balance holes. The shaft seal form can be flexibly selected as packing seal or single/double mechanical seal, and supports cooling, flushing, and sealing system configurations. The entire pump pressure rating strictly complies with API specifications, providing safe, efficient, and long-term stable transfer assurance for process installations.

MAS/MAE/MAFT Series Magnetic Drive Petrochemical Process Pumps

The MAS/MAE series magnetic drive petrochemical process pumps are strictly designed and manufactured in accordance with the API 685​ standard, offering a highly reliable leak-free transfer solution for petrochemical and process industry applications. The products utilize a magnetic coupling drive structure, completely eliminating the risk of shaft seal leakage and significantly enhancing the operational safety of installations, making them particularly suitable for the continuous transfer of flammable, explosive, toxic, and high-value media.

The MAFT series fluoroplastic-lined magnetic drive petrochemical process pumps are designed and manufactured according to the API 685 standard. All wetted parts are made of highly corrosion-resistant materials, allowing for the safe transfer of various concentrated (strong) acids, alkalis, oxidizers, and other corrosive media. The isolation sleeve is made of high-strength special materials, effectively eliminating magnetic eddy current phenomena. This series of pumps from Yongqiu Pump Group not only meets international performance standards, serving as a substitute for high-cost stainless steel or imported chemical pumps, but also prevents industrial leakage, protects the environment, and represents high-end industrial environmental protection equipment that meets the requirements of green chemical equipment.

The magnetic drive pumps feature an overall modular building-block design​ with highly universal and interchangeable parts, making maintenance simple and reliable. They are widely used in petroleum and natural gas processing, oil refining, chemical, chemical fiber, papermaking, metallurgy, electroplating, pharmaceutical, food processing, and environmental protection industries, especially suitable for transferring flammable, explosive, highly toxic, corrosive, and precious media.

MH Series Medium/Light Chemical Process Pumps

The MH series chemical pumps are a newly developed and optimized upgrade based on traditional IH chemical pumps. This series integrates advanced cartridge mechanical seal technology​ and an enhanced bearing structure design. The main pump body can be made of materials such as carbon steel, stainless steel, duplex steel, and titanium, aiming to achieve superior operational performance, more convenient maintenance, and stronger adaptability to outdoor and harsh conditions.

1. Cartridge Mechanical Seal: The shaft sleeve and mechanical seal are integrated into one unit, resulting in a more compact structure that effectively simplifies installation and maintenance procedures.

2. Enlarged Seal Chamber Design: The seal chamber gap is ≥5 mm, significantly improving cooling effectiveness and heat dissipation, effectively extending the service life of the mechanical seal.

3. Advanced Bearing Housing Structure: Supports the installation of temperature and vibration sensors. The bearing housing is independently designed, facilitating condition monitoring and maintenance.

4. Automatic Oil Injection and Air Vent Valve: Integrates lubrication and air venting functions, allowing for oil injection and air venting simultaneously, effectively preventing moisture ingress into the bearing chamber under outdoor conditions.

5. Equipped with Lifting Eyebolts: Facilitates equipment installation, disassembly, and daily maintenance operations.

6. 3Cr13 Stainless Steel Pump Shaft: Offers higher strength, corrosion resistance, and service life, suitable for various chemical media conditions.

MDS Series Back-Pull-Out Centrifugal Pumps

The MDS series back-pull-out centrifugal pumps are optimized based on a horizontal inline pump structure. It is a highly reliable transfer device designed for continuous operation, especially suitable for application scenarios requiring frequent maintenance and with limited maintenance space. The product adopts a back-pull-out structure, allowing for the inspection, repair, or replacement of key components such as the impeller, mechanical seal, and bearings without disconnecting the piping, significantly reducing downtime, and effectively lowering maintenance difficulty and overall operational costs.

The main pump body can be made of materials such as carbon steel, stainless steel, duplex steel, and titanium, offering high structural strength and excellent impact resistance. It is suitable for typical working conditions involving general industrial media, water treatment, and various circulation systems.
