Our FRP Pressure Tanks are designed to withstand high working pressures of 125PSI and 150PSI, making them suitable for various industrial applications. The tanks are manufactured using a combination of epoxy resin and glass fiber winding reinforcement, ensuring strength and durability. The liner of the FRP Filter Tank is made from food-grade PE raw material, which guarantees the safety and purity of the filtered water.

The manufacturing process involves blow molding/rotomolding integrated molding, which results in a seamless and leak-proof tank. The automatic CNC winding technology ensures precise and consistent winding, leading to a higher quality product. The tank mouth is available in threaded or flanged joints, providing flexibility in installation.
Our FRP Pressure Tanks have undergone rigorous testing and certification. They have passed NSF, CE, and ISO9001 certifications, ensuring compliance with international quality standards. The tanks have also been subjected to more than 100,000 fatigue tests, which is four times the burst pressure. This indicates their reliability and ability to withstand extreme conditions. With their high working pressures, durable construction, and certifications, they are a reliable choice for water treatment systems.
Pump and valve packing with the installation and adjustment methods
The effective sealing of the pump and the valve depends on the overall condition of the individual components. Particular care must be taken that the equipment requiring replacement of the packing has been effectively isolated on site and in the system prior to packing. The following is used to guide the maintenance staff, engineers and assemblers to properly install and adjust the packing. The effective sealing of the pump and the valve depends on the overall condition of the individual components. Particular care must be taken that the equipment requiring replacement of the packing has been effectively isolated on site and in the system prior to packing. The following is used to guide the maintenance staff, engineers and assemblers to properly install and adjust the packing. 1, the tools needed in the removal of the old packing root need to use a special tool, and with the fastener pre-gland nut. In addition, regular safety equipment and compliance with relevant safety regulations are required. Prior to installation, first familiarize yourself with the following equipment: Cutter to verify the packing ring, calibrate the torque wrench or wrench, helmet, internal and external calipers, fasteners lubricants, mirrors, pan picker, Tools, vernier caliper, etc. 2. Cleaning and checking 1) Slowly loosen gland nuts in stuffing box to release all residual pressure in packing assembly; 2) Remove all old packing and thoroughly clean stuffing box of shaft / 3) Check shaft / rod for corrosion, dents, scratches or excessive wear; 4) Check other parts for burrs, cracks and wear, they will reduce the life of the packing; 5) Check whether the packing box is too large Clearance, and shaft / rod eccentricity; 6) Replace parts with larger defects; and 7) Check the old packing as a basis for failure analysis to find out the cause of early packing failure. 3. Measure and record the diameter of the recording shaft / rod, the diameter and depth of the stuffing box, and record the distance between the bottom of the stuffing box and the top when sealing the water. 4, select packing 1) to ensure that the selected packing should meet the operating conditions of the system and equipment requirements; 2) According to the measurement records, calculate the packing root cross-sectional area and the required number of packing ring; 3) , To ensure that they are defect-free; 4) Before installation, make sure the equipment and packing are clean. 5, packing ring preparation 1) braided packing in the appropriate size of the shaft winding packing, or use a calibrated packing ring cutter; according to the requirements of neatly cutting the packing into the butt (square) or miter ( 30-45 degrees), cut a ring at a time, and check whether the size with the shaft or stem suitable. 2) Molded packing Make sure that the ring is exactly sized to the shaft or stem, and cut the packing rings if necessary, according to the packing manufacturer's operating instructions or requirements. 6. Install Packing Be careful to install one packing ring each time, enclose each ring around the shaft or stem. Before installing the next ring, make sure the ring is fully seated in the stuffing box and the next ring Should be staggered, at least 90 degrees apart, the general requirements of 120 degrees. After the last ring is installed, tighten the nut by hand and press it down evenly. If there is a water seal, check that it is at the correct distance from the top of the stuffing box. At the same time to ensure that the shaft or stem can rotate freely. 7, adjust the packing 1) pump packing (1) continue to hand tighten the gland nut; (2) open the pump, adjust the gland nut, this time allow a little more leakage; (3) slowly tighten the pressure Cover the nut and gradually reduce the leakage until the leakage reaches an acceptable level; (4) If the leakage suddenly stops, re-screw the gland nut to readjust to prevent overheating of the packing. (5) Adjust the leakage rate to a steady state . 2) Valve Packing Use the packing manufacturer or your company's technical department for torque specifications or percentage compression and tighten the gland nuts as follows: (1) Apply torque to the gland nuts to 30% of full torque or Party compression percentage; (2) repeatedly opening and closing the valve several times, applying full torque when the valve is in the closed position; and (3) repeating steps (2) 3 or 4 times. 8. Fasten and Replace Again After a few hours of operation, check the condition of the gland and tighten if necessary. When the gland can not be further adjusted, the packing must be replaced.
