SFH-W7 Horizontal High Speed Sunflo Industrial Pumps Overhung Type
Product Overview
SFH-W pump series are overhung type, horizontally mounted high speed pumps, mainly composed of motor gearbox, pump body, lubrication system and baseplate. They are stable, reliable, compact in size, easy to maintain, and have long service lives. SFH-W7 pump series are equipped with backflow stabilizers, which improve the pump performance at the low flow section and expand the flow regulation ranges. High-speed shaft system is equipped with advanced bi-directional tilt pad bearings to ensure long time operation of pumps under suction pressure up to 10.0 MPa.

Technical Parameters
Performance Envelopes of SFH-W Horizontal High Speed Pump
High Performance Gearbox
The gearbox casing and gear shaft are the key components of a pump. Heat treatment processes are complex, and the machining accuracy and fit tolerances are stringent. Through years of efforts, a set of complete and time-tested fabrication processes are established. Under such regulations, chemical composition and heat treatment of castings are strictly 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.
High Performance Journal Bearings
Multiple series of self-developed journal bearings can be flexibly combined to satisfy different applications. The successful development of axial, radial and tilt 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.
Fluid Section Optimization
Inducer, impeller, diffuser and pump casing, which are the main components of the fluid section, are optimized with the aid of CFD software.

Test Facilities
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 underwent performance and running tests before shipment to guarantee trouble-free operation on site. Three pump test stands operate independently each with the power of 355KW, 1100KW and 4000KW. 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.
