Compact Sunflo Industrial Pumps SFH-W5 400KW Max Motor Power
Sunflo SFH-W5 Industrial Pumps - The perfect solution for your industrial pumping requirements and demands. SFH-W pump series are overhung type, horizontally mounted high-speed pumps, mainly composed of motor gearbox, pump body, lubrication system, and baseplate.
These pumps are stable, reliable, compact in size, easy to maintain, and have long service lives. SFH-W5 pump series are equipped with backflow stabilizers, which improve pump performance at the low flow section and expand flow regulation ranges. High-speed shaft system is equipped with advanced bi-directional tilting pad bearings to ensure long-time operation of pumps under suction pressure up to 10.0 MPa.

The gearbox casing and gear shaft are key components of the pump. Heat treatment processes are complex, and machining accuracy and fit tolerances are stringent. Through years of effort, a complete and time-tested fabrication process has been established.
Under strict regulations, chemical composition and heat treatment of castings are controlled, multiple stabilization treatments after initial machining of gearboxes are carried out to ensure high strength and stability, and every finished part is strictly tested, recorded, and filed for traceability.
Multiple series of self-developed journal bearings can be flexibly combined to satisfy different applications. The successful development of axial, radial, and tilting pad bearings, suitable for working under high suction pressure and heavy load conditions, greatly improves the stability and reliability of high-speed pumps and broadens their field of applications.
Inducer, impeller, diffuser, and pump casing - the main components of the fluid section - are optimized with the aid of CFD software for maximum efficiency and performance.
After-sales service is performed by well-trained and qualified technicians, capable of swiftly handling any technical issues incurred during installation, commissioning, and production. Ample spare part inventory and quick delivery are available due to our modular design concept.
Professional compressor test facilities, equipped with high-speed and high-precision data acquisition systems, carry out performance and running tests. Major systems include:
- Pump test system
- High-speed bearing test system
- Integral lube oil pump test system
- Rotor dynamic test system
- Turbo performance test system
Every delivered pump undergoes performance and running tests before shipment to guarantee trouble-free operation on site. Three pump test stands operate independently, each with power of 355 KW, 1,100 KW, and 4,000 KW.
Each system runs in a closed loop with a circulating cooling system to prevent temperature rise during tests, which may impact the test process and measuring accuracy. Standard applied: Rotodynamic Pumps - Hydraulic Performance Acceptance Tests - Grade 1 and 2 (GB/T 3216). The uncertainty of pump energy test is better than grade 1.
