7236733/B-10011-5 LSC Submersible Residue Dewatering Pump LSP Self-Priming Residue Dewatering Pump OPERATION MANUAL TSURUMI MANUFACTURING CO., LTD.
INTRODUCTION Thank you for selecting the Tsurumi LSC Submersible Residue Dewatering Pump and LSP Self-Priming Residue Dewatering Pump for your application. This equipment should not be used for applications other than those listed in this manual. Failure to observe this precaution may lead to a malfunction or an accident. In the event of a malfunction or an accident, the manufacturer will not assume any liability.
1 BE SURE TO READ FOR YOUR SAFETY Be sure to thoroughly read and understand the SAFETY PRECAUTIONS given in this section before using the equipment in order to operate the equipment correctly. The precautionary measures described in this section are intended to prevent danger or damage to you or to others. The contents of this manual that could possibly be performed improperly are classified into two categories: WARNING, and CAUTION.
CAUTION Be sure to provide a ground wire securely. Do not connect the ground wire to a gas pipe, water pipe, lightening rod, or telephone ground wire. Improper grounding could cause electrical shock. Prevent a metallic object or dust from sticking to the power plug. Adhesion of foreign object to the plug could cause electrical shock, short-circuit, or fire. Do not use the cabtyre cable, power plug, or power outlet if it is damaged or it is not closely fitted.
PRECAUTIONS DURING MAINTENANCE AND INSPECTION Absolutely turn off the power supply before starting maintenance or inspection, and perform the work after making sure that the impeller has stopped completely.Do not work with wet hands. Failure to observe these cautions may lead to electrical shock or injury.

3 PRIOR TO OPERATION When the pump is delivered, first perform the following checks. Product Inspection While unpacking, inspect the product for damage during shipment, and make sure all bolts and nuts are tightened properly. Specification Check Check the model number to make sure it is the product that was ordered. Be certain it is the correct voltage and frequency. Accessory Check Verify that all accessory items are included in the package. LSC Type • Hose Band ........................................
4 INSTALLATION Do not use the pump in liquids other than plain water, such as oil, salt CAUTION • water, or organic solvents. • Use with a power supply voltage within ± 10% of the rated voltage. • Do not use in the water temperatures outside the range of 0 ~ 40°C, which can lead to failure, electrical leakage or shock. • Do not use in the vicinity of explosive or flammable materials. • Use only in fully assembled state.
Precautions in Installation installing the pump, pay close attention to its center of gravity and WARNING When weight. If it is not lowered into place correctly, it may fall and be damaged or cause injury. CAUTION Do not under any circumstances install or move the pump by suspending it from the cabtyre cable. The cable may be damaged, causing electrical leakage, shock, or fire. (1) •Model LSC The discharge connection is fitted with a 25 mm diameter union hose coupling.
5 ELECTRICAL WIRING Performing electrical wiring Electrical wiring should be performed by a qualified person in accord with WARNING • all applicable regulations. Failure to observe this precaution not only risks breaking the law but is extremely dangerous. • Incorrect wiring can lead to electrical leakage, electrical shock or fire. • Absolutely provide a dedicated earth leakage circuit breaker and a thermal overload relay suitable for the pump (available on the market).
Cabtyre cable CAUTION • If it is necessary to extend the cabtyre cable, use a core size equal to or larger than the original. This is necessary not only for avoiding a performance drop, but to prevent cable overheating which can result in fire, electrical leakage or electrical shock. • If a cable with cut insulation or other damage is submerged in the water, there is danger of water seeping into the motor causing a short. This may result in damage to the pump, electrical leakage, electrical shock, or fire.
6 OPERATION Before starting (1) Make sure once again that the product is of the correct voltage and frequency rating. Using the product at other than rated voltage and frequency will not only lower its performance but may damage the product. CAUTION Note:Confirm the rated voltage and frequency on the model name plate. (2) Confirm the wiring, supply voltage, circuit breaker capacity, and motor insulation resistance. Reference insulation resistance = 20MΩ or greater.
7 MAINTENANCE AND INSPECTION Regular maintenance and inspections are a necessity for continued efficient functioning of the pump. If any abnormal conditions are noticed, refer to the section on troubleshooting (P.15) and take corrective measures immediately. It is recommended that a spare pump be kept ready in case of any problems. Prior to Inspecting the cabtyre cable from the receptacle or terminals, after making WARNING Detach certain the power supply (circuit breaker, etc.) is turned off.
Storage When the pump is out of use for an extended period, wash it and dry it thoroughly, then store it indoors. Note: Always run a test operation before putting the pump back into service. Oil Inspection and Oil change Inspecting Oil Remove the oil plug and tilt the pump to drain a small of oil. If the oil is milky white or has water mixed in with it, the mechanical seal may faulty . In this case the pump will need to be disassembled and repaired.
Disassembly Procedure Note: Before disassembling, be sure to drain the oil. (1) Removing the suction cover and the pump casing Remove the hex bolts and the sealing washers from under the bottom plate and remove the bottom plate from the pump unit. Then, use a wrench to remove the hex bolt with flat washer to remove the stand, O-ring, suction cover, and the pump casing from the pump unit.
Disassembly(LSP) Note: Before disassembly, drain the oil from the pump. (1) Remove the Bottom Plate and Suction Cover Remove the Hex. Bolt and Plain Washer under the Bottom Plate, then remove the Bottom Plate and Suction Cover from the Pump casing. (2) Remove the Impeller With a box wrench or other tool, remove the Impeller Nut, spring washer and Plain Washer, then remove the impeller, Shaft Sleeve and V-Ring from the Shaft. Next, Remove the Pump Casing from pump. Exploded view(LSP1.
9 TROUBLESHOOTING turn off the power before inspecting the pump. Failure to observe this WARNING Always precaution can result in serious accident. Before ordering repairs, carefully read through this instruction manual, then repeat the inspection. If the problem remains, contact your nearest dealer or Tsurumi representative. LSC Problem Pump fails to start; or, starts but stops immediately (within 10 seconds). During operation, the pump stops automatically due to the tripping of the motor protector.
