Product Description

This pump applies to marine emergency survival systems and cabin water removal. It's used for handling sewage with solids and fibers in urban planning, pumping stations, construction, etc., and for gas extraction and irrigation in rural areas.
The motor has an F - class insulation and IP68 enclosure protection.For 1.5 - 7.5 kW pumps, a leakage - measuring electrode in the motor body triggers the controller to alarm and protect the pump when it senses a leak.
For pumps over 7.5 kW, a float switch is in the motor body, a leakage - measuring electrode in the junction box and oil chamber, and super heat overload protection devices in the motor bearings.

1. Excellent adhesion between the coating and the metal substrate.
2. Wide applicable temperature range.
3. Good cathodic disbondment resistance, free of the "cathode screening" effect.
4. Stable electrical insulation to reduce cathodic protection current.
5. Resistant to chemical media corrosion, with good resistance to Cl
6. Similar thermal expansion coefficients of the coating and the steel structure, with good resistance to thermal changes.
7. The coating is easy to repair.

   • Seawater booster pump: 14SH - 90 - 19 seawater pump, speed 1450r/min, 3 sets.
   • Underground seawater pipeline: 4 φ1400 pipelines, about 30m.
   • Bellows expansion joint: 8 units, φ1400×1.2m.
   • Seawater cooling pipe in the steam turbine building: seawater booster pump outlet pipe φ600×12m and tees, tee joints of φ325 - φ525mm, totally 260m.
2. Shenyang Automation Research Institute, Chinese Academy of Sciences
   Key parts of the underwater robot developed by the institute, such as underwater motors, underwater manipulator oil cylinders, and underwater tools, adopted the special KsF coating technology and were successfully used on Nanhai drilling platform Exploration 3 of China West Petroleum Company.

Effect of KsF spray - painting anticorrosion technology on marine pumps

Factory seawater simulation test:
Two 50cL - 30 marine vertical centrifugal pumps were used for the contrast test. The base material of their main parts was the same (cast silicon brass, ZCuZn16Si4). One pump's body, cover, impeller, and gland were treated with KsF severe - corrosion - protection spraying (average coating thickness 0.45mm), and the other was not. The test medium was simulated seawater (11.62kg sea salt added to 0.33m³ fresh water, weight ratio 3.52%). The unpainted pump started the test on September 14, 2004, and the painted one on October 14, 2004, with continuous 24 - hour operation required.
The two pumps were disassembled for the first check on December 2, 2004, reassembled, and continued the test. On March 7, 2005, By then, the unpainted pump had run for 4000h and the painted one for 3380h. The inspection results were as follows:
 

1. No mechanical seal leakage, abnormal vibration, or noise occurred during the operation of the two pumps.
2. The impeller rings and seal rings of the two pumps had slight normal wear.
3. The rubbing surfaces of the mechanical seals of the two pumps had normal wear.
4. The coating surface of the painted pump's body, cover, impeller, and gland was smooth and intact, with no seawater corrosion, coating wear, or peeling. In contrast, the surface of the unpainted pump's body, cover, and impeller had corrosion, which was significantly aggravated compared to the first check.
