CAL Standard Design WARNING Shaft seal parts will not function to stop the pumped liquid completely. When handling such a liquid which may cause serious troubles to the human body, therefore, do not touch the splashing liquid from shaft seal parts.
CAL Optional Design Instruction Manual 0. General Carefully read this Manual before operating the CAL pump. Contents Also, keep this Manual at an easily accessible place. Contents ..................1 All the pump components are manufactured under the strict quality General .................. 1 control system to assure of their specific performance.
Oil lubrication (constant level oiler) Fig 0.3-1 0.4. Construction The CAL pumps provide single-stage, axial single-suction structure for vertical (upward) discharge. The pump casing is of back pull-out type with integral-casted axial suction nozzle and top discharge nozzle and support foot. The pump can be disassembled and internally inspected without removing the casing (1020) from Note1.

When it comes off from the rated flow remarkably and Is each bearing free from abnormal temperature rise? it drives, it causes the following accidents, and do the 3.2.
CAL Optional Design The gland should be slightly recessed from the casing cover. The gland packing should be lightly tightened at the beginning. Then, re-tighten it after running the pump for a certain period. Adjust the gland packing so that liquid leakage from the gland is approx. 10 to 20 cc/min.

4.1. General As its advantageous point, the CAL pump can be disassembled without demounting the volute casing (1020) from the base plate and the pipelines. In disassembling, be careful not to impact and damages the Pump. Refer to the Pump Sectional Drawing submitted at the time of order in disassembling and reassembling.
CAL Optional Design Caution: Do not heat the shaft. 4.2. Disassembling (16) In principle, replace the flat gasket (4000) and O-ring (4120) used for each seal surface with new ones when Follow the sequence below in disassembling disassembling the pump.

CAL Optional Design 7. Troubleshooting Main possible troubles of the pump are as described hereunder. If a trouble occurs with the pump, stop the pump immediately, and take corrective actions depending on the cause and phenomenon of the trouble. If the trouble can not be fixed or the cause can not be identified in spite of having implemented the following measures, examine the content of the trouble in detail.
