The dual-suction seal ring is used to reduce the leak at the impeller.Both inlet and outlet of this pump are placed under the axial line, horizontally and vertical to the axial line, the pump casing is opened in the middle so it is unneccessary to remove the water inlet and outlet pipelines and motor(or other prime movers). The pump moves CW viewing from the clutch to it. The pump moving CCW can also be made, but it should be specially noted at order. The main parts of the pump are: pump casing(1), pump cover (2), impeller (3), shaft(4), dual-suction seal ring(5), muff(6), be-aring(15) etc.and all of them, except the axle which is made of quality carbon steel, are made of cast iron. The material may be replaced with others upon different media.So 80CModel S pump is a single-stage double-suction horizontal split centrifugal pump and used to transport pure water and the liquid of both physical and chemical nature similar to those of water, the maximum temperature of which must not be over 80,suitable for water supply and drainage in factories, mines, cities and electric stations, waterlogged land drainage and irrigation of farming land and carious hydraulic projects.Pump's inlet diameter:150mm()(1)(2)(3)(4)(5)(6)(15)1Check both pump and motor to see if any damages with th- em.2The installat ion height f the pump plus the hydraulic lossof the suck-in pipeline and its speed energy is just the NPSHa of the unit, which should bigger than NPSHr. The dimensions of the basis should be in line with those of in- stallation of the pump unit.3. Installation sequences:The pump is driven directly by means of connecting to it via an elastic clutch. (Set up a stand additionally in case of a rubber band driving).The shaft seal is packing seal and, to cool and lubricate the seal cavity and prevent air from getting into the pump, there is a packing ring between the packing. A small volume of high-pressure water flows into the packing cavity via the tapered beard during the pump's working to act as a water seal.121. Assembly of the rotor's parts: in turn mount the impeller, muff, muff nut, packing sleeve, packing ring, packing gland, mechanical seal, mechanical seal bland, water retai ning r- i ng and bearing on the pump shaft, put on the dual-suction seal ring and then the clutch.2. Check the outer circles of the impeller's seal and the muff on the rotor separately, the radial jumping of which should not be over the settings in the table below.34()3Mount the rotor on the pump casing and adjust the impeller to have its axial position in the middle of the dual-suction seal ring in both sides and then fixed, then fix the gland of the b- earing's body with the fixing screws.4Put on the packing(in case of a packing seal), the paper pad on the middle opened face and the pump cover and tighten the threaded-tail conical pin first and then cover's nut. Mo- unt the packing gland, but do not press the packing too tig- htly, otherwise the muff may get heated to leave a bigger power consumption; while not too loose, or a big leak of liquid and reduced pump efficiency may re sult in. If me-chani cal seal is used, adjust the stud on the gland to ensure no leak with it.After a sse mbl y, move the pump shaft with hand, it should be smooth and uniform without touch. Disassembly can be m- ade with the steps contrary to above ones.INSTALLA TION12NPSHaNPSHaNPSHr 31. Start and stop(1) Before starting, move the rotor of the pump, which should be felt light, smooth and uniform.(2) Close the water outlet valve, prime water into the pump (le- ad water by extracting with a vacuum pump in case of no foot valve). Ensure the pump full of water and no air ne- sted inside of it.(1)(2)(3)(4)0.10.3()(5) 4 567(20)(1) Place the pump on the concrete basis with built-in foot bolts, correct the levelness with the method adjusting the wedge cushi on block an d properly tighten the bolts to prevent them from displacement.(2) Grout concret e between the basis and the pump foot.(3) After the concrete gets solidified, tighten the foot bolts and check the pump's levelness again.(4) Correct the concentricity between the axles of both pump and motor to have them in a straight line. The allowed tol- erance of the non-concentricity of the outer circles of two clutches is 0.1mm and the one of the non-uniform end-face intervals along with the circumference is 0.3mm(another cor rection of which after both water inlet and outlet pipe- lines are connected and a trial movement, the above requ- irements should also be met with).(5) After finding out the rotating direction of the motor is ide- ntical to that of the pump, mount the link pin of the clutch.4Both water inlet and outlet pipelines should be supported by a separate stand and not by the pump body.5 A good air tightness of the combined face between both p- ump and pipeline should be kept, especially the inlet pipel- ine, it must be guaranteed without air leak and without the poss ibility for air to be nested on the unit.6In general, a foot valve can be mounted if the pump is mo- unted above the water level of the water inlet so as to start the pump with priming, it can also use the way of vacuum pu- mp water leading.7In general gate valve and check valve are required to be m- ounted in the water outlet pipeline of the pump(unnecessary for those of a head less than 20m), with the check valve mounted after the gate valve.The above ways of installation mean the pump without a common foundation.For the pump with a common foundation, use the wedge-iron-pad between both foundation and concrete to correct the levelness of the unit, then grout concrete between them. The installation principle and requirements are the same as those for the pump without a common foundation.(1)(2)(),S SERIES SINGLE-STAGE DOUBLE-SUCTION HORIZONTAL SPLIT CENTRIFUGAL PUMP(3) First close the plug of a vacuum or pressure meter, if so m- ounted on the pump, connected to the pump before starting the motor and then open it when the motor move in the nor- mal speed; next, gradually open the water outlet gate va- lve and make it smaller in case of a large flowrater or big-ger or bigger on the contrary.(4) Uniformly tighten the pressing nut on the packing gland to have liquid leak in drops and pay attention to the tempera- ture rise outside of the packing cavity.(5) When to stop the pump, first close the plug of the vacuum or pressure meter and the gate valve on the water outlet p- ipeline, then cut off the power of the motor. Open the squ-are screw plug on the lower side of the pump casing to let the residual water out to prevent frozen cracking in case of a lower ambient temperature.(6) In a long time stop,remove the pump and dry the parts andcoat rust-proof grease on the processed surface.2. Running(1) The maximum temperature of the pump's bearing must not be over 75.(2) It is proper for the volume of the calcium-based grease lub- ricating the bearing to hold a space inside of the bearing body by 1/31/2.(3) Properly press the packing gland in case of a little bit we- ar and replace it in case of too much wear.(4) Take a periodic check of the elastic clutch and take care of the temperature rise with the motor's bearing.(5) During running, stop it at once when noise or other abnor- mal sound is heard to find the cause and settle it.(6) Do not raise the pump speed at will, but lowering it is all- owed. For instance, with this type of pump, the rated rotat- ing speed is n, flowrate is Q, head is H, axle power is N, lo- wered speed is n1, the flowrate, head and axle power after speed lowering are Q 1, H 1 and N 1, respectively.

Report damage immediately to the shipping carrier or to your dealer. The Webtrol Vertical Series pump should remain in the shipping carton until it is ready to be installed. Do not drop or mishandle the pump prior to installation.Always check the pump label against the requirement to make sure you are installing the proper pump specified for the job.Make sure that the pump suction, marked by a sticker, is connected to the liquid source and that the discharge, similarly marked, is connected to the discharge line.Caution:On three phase motor installations, always check for proper motor rotation prior to starting by jogging the motor. Shaft rotation must turn clockwise when viewed from back of the motor.Make sure the motor is correctly wired, refer to instructions on motor name plate.Make sure that the pump base is firmly secured to a solid flat surface and that the suction and discharge lines are aligned and properly supported to prevent pipe strain on the pump.where necessary.Using a funnel, fill the pump body with water until it overflows and replace plug.Alternatively for installations with positive suction heads, close the discharge valve and remove the vent plug. Open the suction valve until liquid flows out the vent plug opening and then replace the vent plug securely and open discharge valve.Caution:Extreme caution should be used if priming the pump in this manner in a hot water application. Replace the coupling guards if previously removed.Warning:Operating the pump without the coupling guards in place can cause physical injury.It is recommended that a bleed valve be installed in the discharge line, or in a line from the vent port to the reservoir. This will allow the pressure in the pump to be relieved for service.Installing a bleed valve is especially necessary in hot water application to prevent injury.Pipe, valves and fittings must have a pressure rating equal to or greater than the maximum system pressure.A bypass or pressure relief valve should be installed in the discharge line if there is any possibility the pump may operate against a closed valve in the discharge line.Minimum flow is required for proper cooling and lubrication of the pump without which, damage and premature failure will occur.3. Position the motor, shaft down, about 1” above the pump assembly. Check the motor for balance and align-ment.4. Ensure that the motor key has been placed firmly into the motor shaft keyway.5. Align the motor key and keyway with the coupling keyway and slowly lower the motor into position ensuring that the key slides into the coupling keyway.6. Prior to lowering the motor completely, rotate the motor so that the mounting holes are aligned with the corre-sponding holes in the pump bracket. After alignment, lower the motor onto the pump head.7. Insert the four motor bolts with lock washers and tighten evenly using an alternating criss cross pattern. Tighten the set screws in the coupling.8. Replace the coupling protection guards.Installation procedures for the following pump models:V10B2S - V10B7S, V20B2S - V20B7S, V40B2S - V40B3S1. Make sure the motor protection guard is removed from the pump end.2. Carefully loosen the screws on the coupling and place motor key in the motor shaft keyway.3. Position the motor vertically over the pump with the keyways lined up on the motor shaft and coupling. Then lower the motor into place.4. With the motor positioned over the pump and the motor shaft correctly inserted in the coupling, rotate the motor so that the mounting bolt holes line up with the corresponding holes in the motor bracket. Insert the mounting bolts with lockwashers and firmly tighten using a criss crossing pattern.Warning:When lifting the pump, use appropriate crane (or hoist), check position and tightness of lift system so that weight of the pump is not unbalanced.Failure to observe this precaution can result in serious accidents.1. Remove the motor as detailed in (Motor Removal) section.2. Isolate the pump by closing the suction inlet and discharge valves.3. Carefully relieve the pressure in the pump by opening the vent or drain plugs.4. Remove the vent plug5. Remove the coupling guards with a Phillips head screwdriver.6. Using an Allen wrench (a T-handle is recommended) loosen and remove the pump coupling bolts and remove the lower coupling section.7. Using 900 snap ring pliers, engage coupling snap ring and lift up to clear end of the pump shaft.8. Loosen and remove the four tie rods.9. Rotate the tie rods counter clockwise to loosen from pump base and remove. This will allow the solid coupling to clear the end of the shaft.10. Gently tap the base of the motor bracket with a soft mallet to loosen the fit on the pump assembly.11. Turn the solid coupling half so that it is aligned with the vent pipe.12. Lift the motor bracket off of the pump assembly by tilting the bracket towards the vent pipe and lifting.13. Remove and retain the pump shaft key.14. Remove the seal plate (casing cover) vertically off of the pump shaft assembly.Caution:Extreme caution should be exercised in this operation since the pump is under system pressure at this point. Use a pressure bleed valve in hot water applications where water temperature could cause physical injury.Pump BaseMechanical Seal Replacement1. Complete disassembly of pump as detailed in previous section.2. Remove the old rotating seal assembly by lifting vertically off the pump shaft. The rotating assembly is rubber boot mounted.3. Press the old stationary seal assembly out of the seal plate from the outside of the seal plate. The stationary seat is rubber cup mounted.4. Place the rotating seal assembly retainer onto the shaft taking care not to scratch or touch the seal face. If touching the seal face in necessary, gently wipe with a clean soft tissue.5. Carefully place the rotating seal assembly onto the shaft using a non-metallic sleeve to push the assembly into place on the shaft, seating the rubber boot snugly.6. Using a non-metallic sleeve, press the stationary seal assembly into the seal plate evenly, seating the rubber boot snugly.7. Reassemble the pump as instructed in (Replacement of Pump Hydraulic Assembly) section.Replacement Of Pump Hydraulic Assembly1. Remove the old mechanical seal assembly, refer to “Disassembly of Pump for Mechanical Seal Replacement”.2. Remove the pump body from the pump casing and remove the o-ring located in the pump casing.3. Ensure that the proper replacement hydraulic (stack) assembly has been selected and provided for the appli-cable pump size.4. Lift the replacement hydraulic (stack) assembly and place it onto the pump casing ensuring that it is firmly seated. Ensure that the pump shaft keyway is aligned vertically with the drain connection on the pump casing for ease of later assembly completion.5. Using a new lower pump body o-ring, apply a light film of silicone grease to the o-ring and place it over the hydraulic assembly and into the pump casing ensuring that it is seated.6. Place the pump body onto the entire assembly and align it with the o-ring installed into the pump casing.7. Using new upper pump body lower o-ring, apply a light film of silicone grease to the o-ring and place it into the o-ring groove on the upper pump body ensuring that it is seated.8. Replace the rotating mechanical seal and seal assembly. Refer to “Mechanical Seal Replacement”9. Replace the stationary mechanical seal Assembly. Refer to “Mechanical Seal Replacement”10. Carefully place the seal plate over the pump shaft Be sure the seal face is not damaged during assembly (cracked, scratched, or chipped) or the seal will leak. Ensure that the vent pipe is vertically aligned with the drain connection of the pump casing.11. Install the pump shaft key into the keyway.12. Place the motor bracket onto the pump seal cover by tilting the assembly over the vent pipe. The solid cou-pling half must be turned toward the vent pipe to ensure that the pump shaft hey will slide into the coupling key-way. The motor bracket should fit snugly onto the stationary seal assembly.13. Replace four tie rods, threading them into the pump mounting base.14. Replace the tie rod washers and nuts onto the tie rods finger tight.15.
