13 CAUTIONS WHEN INSTALLING AND LAYING PIPES YD-GS[H] / GSF series 1Caution when installing If a large amount of air enters during operation, the pump will be unable to pump the liquid and result in a failure. The inlet of the suction pipe attached to the tank should be located lower than 0 cm below the liquid surface. There should be no projection in the piping where air may be trapped in the suction pipe. Do not lay the suction pipe up/down. The suction pipe should have an ascending gradient of more than 1/0 toward the pump. The pipe diameter should be larger than the pump suction bore. If the diameters of the pump suction port and the suction pipe are different, use an eccentric reducer pipe. Connect the eccentric reducer pipe so that the upper side is level. Place a strainer at the inlet of the piping to prevent foreign matter from entering the suction pipe. Clean the strainer periodically to prevent clogging and minimize loss resistance. It is recommended that a check valve be attached to the vertical pipe on the discharge side to prevent water hammer. Place a bypass for air exhaust on the lower section of the check valve when: The discharge pipe is long or when the discharge head is more than m. The end of the discharge pipe is located higher than 9 m above the liquid level of the suction tank. Two or more pumps are used in parallel. Increased liquid temperature causes the piping to expand, leading to pump deformation. Install bent pipes and expansion joints on the pipes to prevent liquid leakage. 2Do not tighten the pump flange excessively. Arrange the pipe flange surface and the pump flange surface parallel to one another and do not tighten the bolts excessively. Excessively tightening the bolts can deform the pump flange if flexible joints, SUS loose flanges or internal packing are used. 3Do not apply weight on the pipes. The weight of the pipe should be completely supported by the pipe support. If the liquid temperature is higher than C, install bent pipes and expansion joints on the pipes so that the pump is not loaded with weight from pipe thermal expansion. Avoid using metal pipes. Use resin pipes only. Follow instructions in 2) and 3) particularly in applications that use sulfuric acid and caustic acid.

While compact in design, it has the high-speed self-priming capacity, priming m less than 2 minutes. Prevents dry running, resistant to dry running 1 2 Unique valveless mechanism (Internationally patented) Heat resistant bushing (Internationally patented) 3 2 SUCTION LIFTm 2minute When pumps run dry, the friction at the contact points causes the shaft and bushing to break down from excess heat. World Chemicals patented heat resistant materials and construction prevents extreme temperature changes at the contact point. Air-lock/cavitations free construction Pockets are created when air enters the chamber during priming. The unique internal design of the rear casing and impeller directs and releases the air without affecting the performance of the pump and prolongs pump life. The most compact design in its class, ideal for limited space installations. Models with 2HP and above use neodymium magnet, guaranteeing high performance in this compact, lightweight GS/GSF series Ideal for liquids with high specific gravity.

15 m less than 2 minutes; the powerful self-priming performance changes the way of production line setup Applications For transferring liquid from the top of the tank and for anti-earthquake and antileakage measures against unexpected pipe broken. For pumping liquid to higher grounds or from underground pits Astounding self-priming power enables pumping from a deep pit or to higher ground 2m. Regardless of bore diameters, the pump can maintain its high self-priming performance. Capable of running with long horizontal suction piping and up-and-down piping The pump can handle a wide range of installation sites: m horizontal piping, up-and-down piping, as well as other demanding conditions. For transferring foamy liquid The valve less self-priming pump equipped with anti-dry-running measures is capable of handling hydrogen peroxide, sodium hypochlorite, sodium carbonate and any other foamy liquid that produces gas in the pump and pipes. For transferring high specific gravity liquid No impeller trimming required. No need for changing models. With the new GV, an increase in motor horsepower and the magnet torque alone will provide the self-priming power to lift high specific gravity liquid. The evolution of the world-leading valveless self-priming pump The world s first valveless pump was developed in 1971 by World Chemical from the unique idea of eliminating check valves, a common cause of pump failures, from the conventional pump design SV:Valveless self-priming pump Mechanical seal PVC (polyvinyl chloride) 1994 GV:Valveless self-priming magnetic pump PP (polypropylene) GV:Valvelessself-priming magnetic pump PP (polypropylene) Molded pump 00 GVF:Valvelessself-priming magnetic pump ETFE (Ethylene-Tetrafluorothylene) Molded pump 02

22 CAUTIONS WHEN INSTALLING AND LAYING PIPES YD-GV / GVF series 1Caution when installing If air enters the pump from couplings on the suction pipe, the pump will be unable to pump the liquid and cause a failure. There is negative pressure in the suction pipe during operation. Improper installation of the coupling lets air into the pump while preventing liquid from entering the pump. This can result in pump failure. Use a suction pipe with the same diameter as the suction inlet. When the piping is larger than the pump diameter, self-suction ability is decreased and self-priming impossible. Keep the minimum liquid level at a depth of more than double the suction pipe bore diameter from the tip of the suction pipe. If the liquid level is lower, air can enter the pump and cause dry running. Place a strainer at the inlet of the piping to prevent foreign matter from entering the suction pipe. Clean the strainer periodically to prevent clogging and minimize loss resistance. It is recommended that a check valve be attached to the vertical pipe on the discharge side to prevent water hammer. Place a bypass for air exhaust on the lower section of the check valve when: Problems in self-priming can be expected if an air vent pipe is not installed. The discharge pipe is long or when the discharge head is more than m. The end of the discharge pipe is located higher than 9 m above the liquid level of the suction tank. Two or more pumps are used in parallel. Increased liquid temperature causes the piping to expand, leading to pump deformation. Install bent pipes and expansion joints on the pipes to prevent liquid leakage. 2Do not tighten the pump flange excessively. Arrange the pipe flange surface and the pump flange surface parallel to one another and do not tighten the bolts excessively. Excessively tightening the bolts can deform the pump flange if flexible joints, SUS loose flanges or internal packing are used. 3Do not apply weight on the pipes. The weight of the pipe should be completely supported by the pipe support. Priming water; Air vent Gate valve Check valve Discharge pipe Gate valve Pipe support Pressure gauge If the liquid temperature is higher than C, install bent pipes and expansion joints on the pipes so that the pump is not loaded with weight from pipe thermal expansion.
