世界化工大流量磁力泵YD-405GS/GSF
| Gas Seal Mechanism | | | The gas seal mechanism prevents contamination inside the pump chamber by sealing has produced from the chemical within the pump. This mechanism also places a dry seal made of rubber in the shaft to protect the motor and the atmosphere of an operational environment.
During operation, the tip of the dry seal lip moves by centrifugal force, and rotates without contact. At the same time, it prevents the leakage of gas and the lip closely adheres during stop to seal gas. Moreover, any leaked gas is immediately released by ventilation, and the oil seal firmly guards the motor bearing. In this way, the service life of the pump and operation environment is protected from gas contamination by the triple gas seal mechanism. | |
| | Resistance to Chemicals | | | The main body of DRYFREE is composed of a carbon fiber reinforced polypropylene (CFR PP) resin, which resists corrosion from a wide range of chemicals. It is also constructed keep metallic parts from contacting the liquid. This unique design combined with the resin construction enables the pump to withstand a much wider range of chemicals than conventional vertical pumps. |
世界化工大流量磁力泵YD-405GS/GSF | | Resistance to Heat | | | CFR PP is not only resistant to corrosion but is also resistant to heat. DRYFREE, which uses this resin for the main body, stands out as an excellent heat-resisting performance pump among the high corrosion resisting chemical pumps. |
世界化工大流量磁力泵YD-405GS/GSF | | Sealless Construction | | | The key to sealing liquid in a pump without incorporating a seal in the liquid that passes inside the pump and the impeller construction. We have successfully developed "Liquid Seal" by utilizing viscosity, pressure and frictional resistance of the liquid, and by balancing the pressure with the unique impeller construction.
The impeller construction is designed so that the pumping blades are located on the front of the impeller main plate, seal blades on the rear, and the protrusion rings on the outside of the seal blades. In addition, the outside diameter of the impeller main plate is larger than the diameter of the protrusion rings. The liquid, which moves to the shaft by the internal pressure during operation, is stopped by pressure in the opposite direction of the protrusion ring and seal blade, and works as liquid seal. When a great resistance is applied on the suction side, air is liable to be sucked from the axial direction. However, liquid frictional resistance is produced between the pressure-balanced liquid and the impeller main plate, the protrusion ring and casing fixed, wall, which prevents air from being sucked to obtain a high vacuum. |
世界化工大流量磁力泵YD-405GS/GSF | | Reducing Air Entrapment and Improving Suction Performance | | | The problem of "air lock", liable to conventional sealless pumps, has been successfully solved in the DRYFREE through the adoption of a new impeller design. First, minimizing the size of the seal blade has reduced the loss resistance. Second, providing barrier walls such as protrusion rings have further reduced air entrapment. This new construction is useful in increasing the airtightness within the pump, and in improving stable suction performance.
The new construction has other additional advantages. It is capable of pumping high temperature fluids that were difficult to pump because of maximum vapor tension, and can cope with suction side piping that has great loss resistance. |
世界化工大流量磁力泵YD-405GS/GSF | | Strong Against Dry Running | | | Constructed without parts such as mechanical seal and bushing, DRYFREE will not generate heat when it runs dry. The pump has no consumable parts and is even capable of handling small amounts of slurry. |
