Pump Structure and Features
The wetted parts and the main shaft of this GDF(2) series Stainless steel centrifugal pump are made of high-quality ZG06Cr19Ni10 stainless steel for extended service life. If the wetted parts are required in materials such as ZG1Cr18Ni9Ti or ZG1Cr18Ni12Mo2Ti, please specify this when placing the order.
The suction and discharge ports of the stainless steel centrifugal pump are aligned on the same axis and have the same diameter, allowing it to be installed directly in the pipeline like a valve. Its compact size, light weight, and easy installation make it more space-efficient than conventional horizontal pumps.
The GDF(2) stainless steel centrifugal pump features a top-access design, allowing the pump cover to be removed for impeller and mechanical seal replacement without disconnecting the suction or discharge piping, which makes maintenance much easier. It is also fitted with a high-quality fluororubber mechanical seal for leak-free performance.



Product Overview
The GDF(2) series Stainless steel centrifugal pump is a new-generation energy-efficient, high-performance product developed by our company in response to evolving market demands and based on a brand-new design concept.
The product is designed in compliance with the Chinese national standard GB/T 5656, Technical Specifications for Centrifugal Pumps (Class I).
The GDF(2) Stainless steel centrifugal pump features a single-stage, single-suction, direct-coupled structure, resulting in a more compact design, reduced installation space, smaller size, and lighter weight.
GDF(2) Stainless steel centrifugal pump key advantages include compact construction, high efficiency and energy savings, low noise, durability, and simple, convenient maintenance.

Advantage Of Stainless Steel Centrifugal Pump

Full SS304 Wetted Components
All flow-passage parts of the GDF(2) stainless steel centrifugal pump are made of high-grade stainless steel 304,ideal for environments with stringent hygiene and safety standards.

Stainless Steel Protective Guard
The vertical pump cover features a durable guard plate to prevent debris and foreign contaminants from entering.

Proprietary High-Cooling Housing
Our self-designed motor housing and fan cover maximizes the heat dissipation surface area, effectively lowering motor temperature rise for stable operation.

Compact Close-Coupled Structure
The integrated long-shaft direct-drive design ensures a compact footprint, making it perfect for space-limited installations.
Application
The GDF(2) series Stainless steel centrifugal pump mainly used for pumping and transferring non-corrosive or mildly corrosive liquid media at normal temperatures, with physical and chemical properties similar to water. It is widely applied in domestic water supply, pure water systems, soft drink transfer, pharmaceutical processing, food processing, breweries, dairy liquid transfer, marine aquaculture, as well as supporting equipment for electroplating, light chemical industries, and wastewater treatment systems.
