  • Page 4: Introduction

    This Installation, Operation, and Maintenance manual is designed to help you get the best performance and longest life from your Remko pump. This pump is a RT 080 Series, semi-open impeller, self priming centrifugal model with a suction check valve.

  • Page 5: Section A Safety

    SECTION A SAFETY These warnings apply to RT series basic pumps. Remko has no control over or particular knowledge of the power source which will be used. Refer to the manual accompanying the power source before attempting to begin operation.

  • Page 6: Section B - Installation

    50% of the maximum permissible operating pressure as shown on the pump performance curve. For further assistance, contact your Remko distributor. Pump Dimensions See Figure 1 below for the approximate physical dimensions of this pump.

  • Page 7: Preinstallation Inspection

    If the maximum shelf life has been exceeded, or if anything appears to be abnormal, contact your Remko distributor or the factory to determine the repair or updating policy. Do not put the pump into service until appropriate action has been taken.

  • Page 8: Suction And Discharge Piping

    3. SUCTION AND DISCHARGE PIPING Pump performance is adversely affected by increase suction lift, discharge elevation. And friction losses. See the performance curve and operating range shown on Page 20 to be sure your overall application allows pump to operate within the safe operation range.

  • Page 9: Sealing

    Sealing Since even a slight leak will affect priming, head, and capacity, especially when operating with a high suction lift; all connections in the suction line should be sealed with pipe dope to ensure an airtight seal. Follow the sealant manufacturer's recommendations when selecting and applying the pipe dope.

  • Page 10: Discharge Lines

    Automatic Air Release Valves are reliable, and require minimum maintenance. See AUTOMATIC AIR RELEASE VALVE in this section for installation and theory of operation of the Automatic Air Release Valve. Contact your Remko distributor for selection of an Automatic Air Release Valve to fit your application.

  • Page 11: Automatic Air Release Valve

    If the installation involves a flooded suction such as below-ground lift station. A pipe union and manual shut-off valve may be installed in the bleed line to allow service of the valve without shutting down the station, and to eliminate the possibility of flooding. If a manual shut-off valve is installed anywhere in the air release piping, it must be a full- opening ball type valve to prevent plugging by solids.

  • Page 12: Air Release Valve Installation

    Contact your Remko distributor for information about an Automatic Air Release Valve for your specific application.

  • Page 13: Alignment

    NOTE: Check Rotation, Section C, before alignment of the pump. When mounted at the Remko factory, driver and pump are aligned before shipment. Misalignment will occur in transit and handling. Pumps must be checking alignment, tighten the foundation bolts. The pump casing feet and/or pedestal feet, and the driver mounting bolts should also be tightly secured.

  • Page 14: V-Belt Drives

    Figure 7. Aligning Non-Spider Figure 6. Aligning Spider Type Couplings Type Couplings Align non-spider type couplings by using a feeler gauge or taper gauge between the couplings halves every 90 degrees. The coupling is in alignment when the hubs are the same distance apart at all points (see Figure7 above).

  • Page 15: Section C - Operation

    SECTION C – OPERATION Review all SAFETY information in Section A. Follow instructions on all tags, labels and decals attached to the pump. This pump is designed to handle mild industrial corrosives, mud or slurries containing large entrained solids. Do not attempt to pump WARNING! volatile;...

  • Page 16: Starting

    9. STARTING Consult the operations manual furnished with the power source. Rotation The correct direction of pump rotation is counterclockwise when facing the impeller. The pump could be damaged and performance adversely affected by incorrect rotation. If pump performance is not within the specified limits (see the curve on page 20), check the direction of power source rotation before further troubleshooting (figure 9).

  • Page 17: Liquids Temperature And Overheating

    Never replace this valve with a substitute which has not been specified or provided by Remko. Strainer Check If a suction strainer has been shipped with the pump or installed by the user, check the strainer regularly, and clean it as necessary.

  • Page 18: Stopping

    11. STOPPING Never halt the flow of liquid suddenly. If the liquid being pumped is stopped abruptly, damaging shock waves can be transmitted to the pump and piping system. Close all connecting valves slowly. On engine driven pumps, reduce the throttle speed slowly and allow the engine to idle briefly before stopping.

  • Page 19: Section D - Troubleshooting

    SECTION D - TROUBLESHOOTING Review all SAFETY information in Section A. Before attempting to open or service the pump: WARNING! 1. Familiarize yourself with this manual. 2. Lock out or disconnect the power source to ensure that the pump will remain inoperative. 3.

    APPROX. 152MM LONG APPROX. 356 MM LONG Figure 13. Rotating Assembly Tool To install the tool, remove the air vent (8, Figure 11, Page 23) from the bearing housing, and screw the longest length of pipe into the vent whole until fully engaged.

  • Page 30: Shaft And Bearing Reassembly And Installation

    Shaft and bearing disassembly in the field is not recommended. These operations should be performed only in a properly equipped CAUTION! shop by qualified personnel. Remove the bearing housing drain plug (23) and drain the lubricant. Clean and reinstall the drain plug. Disengage the hardware (13 and 14) and slide the bearing cap (15) and oil seal (9) off the shaft.
  • Page 31 Most cleaning solvents are toxic and flammable. Use them only in a well-ventilated area free from excessive heat, sparks, and flame. WARNING! Read and follow all precautions printed on solvent containers. Inspected the shaft for distortion, nicks or scratches, or for thread damage on the impeller end.

  • Page 32: Seal And Installation

    Press the outboard oil seal (9) into the bearing cap (15) with the lip positioned as shown in figure 11, page 23. Replace the bearing cap gasket (21), and secure the bearing cap with the hardware (13 and 14). Be careful not to damage the oil seal lip on the shaft keyway.
  • Page 33 To ease installation of the seal, lubricate the shaft sleeve O-ring and the external stationary seat O-ring with a very small amount of light lubricating oil. See Figure 14, page 30 for seal part identification. Slide the tube over the shaft threads, and then slide the O-ring off the end onto the shaft.

  • Page 34: Impeller Installation

    A new seal assembly should be installed any time the old seal is removed CAUTION! from the pump. Reusing an old seal could result in premature failure. Handle the seal parts with extreme care to prevent damage. Be careful not to contaminate precision finished faces;...

  • Page 35: Rotating Assembly Installation

    NOTE: If the rotating assembly has been installed in the pump casing, this clearance may be measured by reaching through the priming port with a feeler gauge. NOTE: Proceed with Rotating Assembly Installation before installing the impeller cap screw and washer (10 and 12). The rotating assembly must be installed in the pump casing in order to torque the impeller cap screw.

  • Page 36: Back Cover Installation

    It is recommended that the pressure relief valve assembly be replaced at each overhaul, or any time the pump overheats and activates the valve. Never replace this valve with a substitute which has not been specified or provided by Remko. Periodically, the valve should be removed for inspection and cleaning. When reinstalling the relief valve, apply 'Loctite Pipe Sealant With Teflon No.

  • Page 37: Seal Assembly

    16. LUBRICATION Seal Assembly (Figure 11, Page 23) Before starting the pump, remove the vented plug (8) and fill the seal cavity with approximately 0,6 litres of SAE No. 30 non-detergent oil, or to a level just below the tapped vented plug hole. Clean and reinstall the vented plug. Maintain the oil at this level.
