Self-priming seawater pump FRP material has its unique strong corrosion resistance, small friction resistance, high transport capacity, strong adaptability, simple construction method, easy maintenance etc. advantages. It has been widely used in the offshore oil platform in many systems. FRP pump can resist salt, acid, sea water etc. corrosion. SZ type fiberglass reinforced plastics corrosion resistant self-priming pump. The flow components for SZ fiberglass self priming pump are made of the modified phenolic fiberglass reinforced plastic material by high temperature molding. The pump has the advantages such as light weight, high strength, no deformation, high temperature resistance, corrosion resistance and easy maintenance etc. Mechanical seal for the pump is WB2 fitted outside type F4 corrugated mechanical seal which is reliable and has a long service life. SZ type fiberglass self priming pump has good self priming performance. The pump body is equipped with a liquid suction chamber, liquid storage chamber, liquid back check valve and reflux hole. Before the pump works, keep a quantitative liquid in the pump body and exhaust the air in the pipe and then the pump can transfer the liquids. The pump works without foot valve and simplifies the pipeline. Suction height: 4meters. SZ type fiberglass self priming pump is widely used to transfer various non- oxidizing acids(Hydrochloric acid, dilute sulfuric acid, formic acid, acetic acid, butyric acid, phosphoric acid)etc corrosive liquids which is not easy to crystallize and temperature is no higher than 100 degree Celsius)in petrochemical, smelting, dyes, printing and dyeing, pesticides, rare earth, fertilizer and other industries.

ZXL directly-coupled self-priming pump is developed based on the ZX flexible shaft coupling self-priming pump. It has a horizontal structure, and the pump and motor are coaxially connected. Advantages 1 - Compact structure. It has a beautiful appearance, and occupies less space. If an IP55 outdoor motor is used, there is no need for a pump room and it can be placed outdoors for use. 2 - Smooth operation, low noise, and high concentricity of components. The motor and pump are directly connected, simplifying the intermediate structure and increasing the smoothness of operation. The impeller has dynamic and static balance, no vibration during operation, low noise, extending the service life of bearings, and improving the operating environment. 3 - The shaft seal adopts high-quality mechanical seals, and the dynamic and static rings are made of hard alloy, which is wear-resistant, leak free, and has a long service life. 4 - Adopting advanced hydraulic models, it has the characteristics of high efficiency and good performance. 5 - Easy to install, use, and maintain. The discharge pipeline does not require a check valve, and the suction pipeline does not require a bottom valve, thus simplifying the pipeline system and improving working conditions. 6 - Unique structure and good self-priming performance, only a certain amount of liquid needs to be stored in the pump body before operation. Usage conditions: 1 - The ambient temperature is ≤ 40 ℃, the altitude is ≤ 1000m, the relative humidity is ≤ 95%, the medium temperature is ≤ 80 ℃, and it is required to reach 200 ℃. 2 - The self-priming height should not exceed the specified value of 5-6.5 meters, and the length of the suction pipe should be ≤ 10 meters Application 1 - ZXL self-priming pump is suitable for industrial and urban water supply and drainage, environmental protection, construction, fire protection, chemical, pharmaceutical, dyeing, printing and dyeing, brewing, electricity, electroplating, papermaking, industrial and mining flushing, equipment cooling, etc. The temperature of the medium used should not exceed 80 ℃, the viscosity should be ≤ 100 cP, and the solid content should be below 30%. 2 - Using bronze impellers and explosion-proof motors, it is suitable for oil depots, gas stations, oil tankers, oil tankers, docks, oil trucks, airports, and transporting gasoline, kerosene, diesel, aviation kerosene, etc. separately. If corrosion-resistant mechanical seals and stainless steel materials are used instead, they can also be applied to chemical, pharmaceutical, brewing, electroplating, printing, papermaking, power mining, etc. The conveying medium temperature is -20 ℃ -80 ℃, the viscosity is ≤ 100%, and the solid content can reach below 30%. The ZXL series direct coupled self-priming pump is particularly suitable for oil tankers or water transport ships, and can also be used as a sweeping pump with good sweeping effect.

Seal rings are vital in preventing fluid or gas leakage across a wide range of equipment. The material of the seal ring largely determines its effectiveness and durability under specific conditions such as temperature, pressure, and chemical exposure. Below are the most common seal ring materials and their typical applications: · Nitrile Rubber (NBR): Ideal for mineral oils, lubricants, and mildly aggressive fluids. It performs well between –40°C and +120°C and is widely used in automotive, hydraulic, and general industrial applications due to its affordability and reliability. · Fluorocarbon Rubber (FKM): Known for outstanding resistance to high temperatures (up to +250°C) and aggressive chemicals. Commonly used in chemical plants, engines, and fuel systems where sealing performance is critical under extreme conditions. · Silicone Rubber (VMQ): Offers excellent flexibility and low-temperature resistance (down to –60°C). It is favored in food processing, medical devices, and electronic equipment that require high hygiene and environmental safety. · Ethylene Propylene Diene Monomer (EPDM): Resists steam, water, brake fluids, and ozone well. Frequently found in water treatment systems, solar heating units, and outdoor applications. · Polytetrafluoroethylene (PTFE): Chemically inert and resistant to almost all aggressive substances. With high temperature tolerance and low friction, it is suitable for chemical processing, pharmaceutical production, and cleanroom environments. · Hydrogenated Nitrile Rubber (HNBR): An upgraded version of NBR that provides enhanced heat resistance and mechanical strength. It performs well in high- pressure and dynamic sealing situations. Selection Advice: Choosing the right seal ring material requires consideration of multiple factors—operating temperature, fluid compatibility, pressure range, dynamic vs. static use, and expected lifespan. For standard conditions, NBR is often sufficient. In high-temperature or corrosive environments, FKM or PTFE is recommended. For food-grade or medical applications, VMQ or EPDM is more appropriate. Selecting the optimal material not only improves sealing performance but also reduces downtime and maintenance costs, ultimately enhancing overall equipment efficiency.
