Working Condition：
Max. Head: 190 m
Max. Flow: 3780 m³/h
Max. Liquid temperature: 80°c
Speed: 1480/2980 rpm at 50Hz
Max. Working pressure: 16 bar as standard
Materials:copper, cast iron, ductile iron, 316 stainless steel, 416; 7 rust steel, two-way steel, Hastelloy, Monel, titanium alloy and No. 20 alloy.
Design features:
• The inlet and outlet flanges of the pump body are all located in the lower pump body, so that the rotor can be taken out without disassembling the system pipeline, which is convenient for maintenance. Part of the pump body adopts dual-channel design to reduce the radial force, thereby extending the mechanical seal and bearing life.
• The hydraulic design of the impeller of the split pump adopts the most advanced CFD technology, thus improving the hydraulic efficiency of the OJS pump. The impeller is dynamically balanced to ensure the smooth operation of the OJS pump.
• The shaft diameter is thicker and the bearing spacing is short, which reduces the shaft deflection and prolongs the life of the mechanical seal and the bearing. The shaft sleeve can be made of many different materials to prevent the shaft from being corroded and worn, and the shaft sleeve can be replaced.
• Wear ring The replaceable wear ring is used between the pump body and the impeller to prevent the wear of the center-split pump body and the impeller. It is convenient to replace and low in maintenance costs. At the same time, it ensures the running clearance and high work efficiency. Either packing or mechanical seal can be used, and the sealing device can be replaced without removing the pump cover.
• The suction port and discharge port of the horizontal double-suction centrifugal pump are below the pump shaft line, and are perpendicular to the axis. All parts can be removed by uncovering the pump cover during maintenance without disassembling the motor and pipeline.
