Self-Priming Oil Pump: CYZ-A Type Explosion-Proof Self-Priming Centrifugal Pump

The CYZ-A type self-priming centrifugal oil pump produced by our company is a new pump product developed after digesting, absorbing, and improving relevant technical information from both domestic and international sources. It fills a domestic gap. This self-priming centrifugal pump is an ideal product for the petroleum industry, suitable for land oil depots and oil tankers, and is also applicable for use as a marine cargo oil pump, bilge pump, fire pump, and ballast pump, as well as for machine cooling water circulation. It can transport petroleum products such as gasoline, kerosene, diesel, and aviation kerosene, as well as seawater and fresh water, with a medium temperature range of -20℃ to 140℃. For transporting chemical liquids, a corrosion-resistant mechanical seal can be used. **Product Features of CYZ-A Type Self-Priming Centrifugal Oil Pump:** This pump belongs to the self-priming centrifugal pump category. The self-priming centrifugal pump has advantages such as simple structure, convenient operation, smooth operation, easy maintenance, high efficiency, long service life, and strong self-priming capability. No bottom valve is required in the pipeline; before operation, it is only necessary to ensure that a certain amount of oil is stored in the pump body. When used on oil tankers or water transport vessels, it can also serve as a bilge pump, providing excellent bilge cleaning performance. This self-priming centrifugal pump is made of carefully selected materials, and the seal uses hard alloy mechanical seals, ensuring durability. The discharge pipeline does not require the installation of a safety valve, and the suction pipeline does not require the installation of a bottom valve, thereby simplifying the pipeline system and improving working conditions. **Structural Diagram of CYZ-A Type Self-Priming Centrifugal Oil Pump:**  **Main Performance Parameter Table of CYZ-A Self-Priming Centrifugal Pump:** | Model | Motor Power (kw) | Speed (r/min) | Diameter (mm) | Flow (m³/h) | Head (m) | Suction Height (m) | |----------------|------------------|----------------|----------------|--------------|----------|---------------------| | 25CYZ-A-20 | 1.1 | 2900 | 25 | 3.2 | 20 | 6 | | 25CYZ-A-20 | 1.5 | 2900 | 25 | 3.2 | 32 | 6 | | 32CYZ-A-20 | 3 | 2900 | 32 | 3.2 | 50 | 6 | | 40CYZ-A-20 | 1.5 | 2900 | 40 | 6.3 | 20 | 5 | | 40CYZ-A-32 | 2.2 | 2900 | 40 | 6.3 | 32 | 5 | | 40CYZ-A-40 | 4 | 2900 | 40 | 10 | 40 | 5 | | 40CYZ-A-50 | 4 | 2900 | 40 | 6.3 | 50 | 5 | | 50CYZ-A-12 | 1.5 | 2900 | 50 | 12.5 | 12 | 5 | | 50CYZ-A-20 | 2.2 | 2900 | 50 | 15 | 20 | 5 | | 50CYZ-A-30 | 3 | 2900 | 50 | 12.5 | 30 | 5 | | 50CYZ-A-35 | 4 | 2900 | 50 | 12.5 | 35 | 5 | | 50CYZ-A-40 | 4 | 2900 | 50 | 10 | 40 | 5 | | 50CYZ-A-50 | 5.5 | 2900 | 50 | 12.5 | 50 | 5 | | 50CYZ-A-60 | 7.5 | 2900 | 50 | 12.5 | 60 | 5 | | 50CYZ-A-75 | 11 | 2900 | 50 | 15 | 75 | 5 | | 65CYZ-A-15 | 3 | 2900 | 65 | 30 | 15 | 4 | | 65CYZ-A-32 | 5.5 | 2900 | 65 | 25 | 32 | 5 | | 65CYZ-A-50 | 7.5 | 2900 | 65 | 25 | 50 | 5 | | 65CYZ-A-70 | 15 | 2900 | 65 | 25 | 70 | 5 | | 80CYZ-A-13 | 3 | 2900 | 80 | 35 | 13 | 3.5 | | 80CYZ-A-17 | 4 | 2900 | 80 | 43 | 17 | 3.5 | | 80CYZ-A-22 | 5.5 | 2900 | 80 | 40 | 22 | 3.5 | | 80CYZ-A-25 | 7.5 | 2900 | 80 | 50 | 25 | 4 | | 80CYZ-A-32 | 7.5 | 2900 | 80 | 50 | 32 | 4 | | 80CYZ-A-40 | 11 | 2900 | 80 | 50 | 40 | 4 | | 80CYZ-A-55 | 18.5 | 2900 | 80 | 60 | 55 | 4 | | 80CYZ-A-70 | 22 | 2900 | 80 | 60 | 70 | 4 | | 100CYZ-A-20 | 7.5 | 2900 | 100 | 80 | 20 | 3.5 | | 100CYZ-A-25 | 11 | 2900 | 100 | 100 | 25 | 4.5 | | 100CYZ-A-32 | 15 | 2900 | 100 | 100 | 32 | 4.5 | | 100CYZ-A-40 | 18.5 | 2900 | 100 | 100 | 40 | 4.5 | | 100CYZ-A-50 | 22 | 2900 | 100 | 100 | 50 | 4.5 | | 100CYZ-A-65 | 30 | 2900 | 100 | 100 | 65 | 4.5 | | 100CYZ-A-75 | 30 | 2900 | 100 | 100 | 75 | 4.5 | | 150CYZ-A-20 | 18.5 | 1450 | 150 | 180 | 20 | 4.5 | | 150CYZ-A-30 | 30 | 1450 | 150 | 170 | 30 | 4.5 | | 150CYZ-A-45 | 37 | 2900 | 150 | 160 | 45 | 4.5 | | 150CYZ-A-55 | 45 | 2900 | 150 | 160 | 80 | 4.5 | | 150CYZ-A-65 | 55 | 2900 | 150 | 170 | 65 | 4.5 | | 150CYZ-A-80 | 55 | 2900 | 150 | 160 | 80 | 4.5 | | 200CYZ-A-32 | 90 | 1450 | 200 | 400 | 32 | 4.5 | | 250CYZ-A-50 | 90 | 1450 | 250 | 400 | 50 | 4.5 | | 300CYZ-A-50 | 110 | 1450 | 300 | 500 | 50 | 4.5 |
