  • Page 19: Storing

    VSP CHEM Vertical Sump Pump 3.4 STORING CAUTION Storing any pump for any length of time presents a few challenges. Dirt, sand and moisture can wreak havoc on parts with close clearances, such as running clearances between impellers and cases and between bearings and shafting. Dirt and sand working their way through these areas can result in wear and opening up of wear ring clearances to an extent that the efficiency of the pump may be affected shortly after start up.
  • Page 20 VSP CHEM Vertical Sump Pump Keep the pump moisture-free by the following two means: Spray the pump case, bearing frame with acid-free, moisture-free, protective oil or kerosene. WARNING Pumping hot liquids causes the external surface temperature to become equally hot.

  • Page 21: Motor (Driver) Storage

    Return the unit to the shipping crate. When the pump is to be installed, remove all the protective coatings and desiccant or drain all oils. One month before installation, a Ruhrpumpen representative should be employed to conduct a final inspection. 3.4.3 Motor (Driver) Storage To properly store the motor (driver) for periods longer than one month, follow the manufacturer´s...
  • Page 22 VSP CHEM Vertical Sump Pump COMMENT The electric motor and drive assembly is a sub-component of the pump (set) with its own installation, operating, and maintenance guidelines. All details can be found on name-plate affixed to the drive(s). Such devices have their own notified body approval, as indicated on the name-plate where applicable, and Conformity Risk Assessments.

  • Page 23: Conservation

    VSP CHEM Vertical Sump Pump o A third option is to use an auxiliary heat source and keep the windings warm by either convection or blowing warm dry air into the motor. ATTENTION Be careful not to overheat, since keeping the temperature of the motor frame 9°F (5°C) above the surrounding ambient temperature is sufficient.
  • Page 24 VSP CHEM Vertical Sump Pump ATTENTION Anticorrosive layers inside the pump housing must be removed with process neutral solvents before commencing pump operation. WARNING When removing the protective coating with a neutral solvent, follow the safety instructions of the solvent manufacturer carefully.

  • Page 25: Installation

    API Recommended Practices 686. IMPORTANT The design of foundations is not the responsibility of Ruhrpumpen. It is therefore recommended that the customer consult a competent specialist skilled in the field of foundations, to insure proper design/installation of the foundation.

  • Page 26: Grouting

    VSP CHEM Vertical Sump Pump Since the pump unit is mounted directly on a sump cover or flange type mounting plate, it should be located as near as possible to supporting beams or building walls to prevent deflection and vibration.

  • Page 27: Equipment/Material Required

    VSP CHEM Vertical Sump Pump 4.2.1 Equipment/Material Required • Grout Mix: Non shrink type. • Sufficient lumber for foundation template and grout trough • Risers or funnels for guiding grout. • Sufficient oil paint for grout protective covering. • Dial indicator.
  • Page 28 VSP CHEM Vertical Sump Pump Provide a form around the baseplate to contain the grout. The form should be chamfered at all corners. ATTENTION Grout forms should be attached with drilled anchors. Do not power nail. ATTENTION Apply three coats of paste wax to the inside surfaces of the forms in order to prevent adherence.

  • Page 29: Equipment Necessary For Installation

    Do not use grout to fill the jackscrew’s holes; use a sealant material instead. Tighten the foundation bolts with an appropriate torque value. In case of doubt, please contact your Ruhrpumpen representative. Apply oil paint to exposed grout to protect from air and moisture.

    VSP CHEM Vertical Sump Pump 5. PIPING AND ALIGNMENT WARNING These units are furnished for a specific service condition. Any change in the hydraulic system may affect the pump performance adversely. WARNING The connection of the piping must be carried out with utmost care; otherwise, the pumping medium can escape during operation, which can seriously endanger the operating personnel.

  • Page 38: Piping The System

    API Recommended Practices 686. IMPORTANT The design of piping and related systems is not the responsibility of Ruhrpumpen. It is, therefore, recommended that the customer consult a competent specialist skilled in the field of piping to insure proper design/installation of all the piping.
  • Page 39 VSP CHEM Vertical Sump Pump ATTENTION The check valve should be installed between the gate valve and discharge flange in order to permit its inspection. Disconnect the piping from the pump if you heat one side of the pipe to align the pipe to the pump.
  • Page 40 VSP CHEM Vertical Sump Pump ATTENTION Make sure that there are isolation block valves at the pump for each type of auxiliary piping. WARNING Do not install unsupported piping on the pump. ATTENTION Make sure electrical connections do not impose any stress on the pump unit.

  • Page 41: Mounting And Aligning Driver

    VSP CHEM Vertical Sump Pump ATTENTION It is important to confirm that the pump can be moved out from the soleplate without cutting or welding. WARNING Do not use drifts or cheater bars to force alignment of bolt holes – serious damage to the pump will result.

  • Page 42: Impeller Lift

     Use an original motor or a motor of identical design from the same manufacturer.  The permissible temperature limits at the motor flange and motor shaft must be higher than the temperatures generated by the pump. (Contact Ruhrpumpen for temperatures).

  • Page 46: Lubrication

    VSP CHEM Vertical Sump Pump 6. LUBRICATION Correct lubrication is essential to the pump’s proper performance. VSP Chem pump systems require lubrication in two separate areas: the thrust ball bearings and the shaft bushings. 6.1 BEARING LUBRICATION 6.1.1 Grease Lubricated Bearings Grease lubricated pump bearings are prelubricated at the factory before shipment.
  • Page 47 VSP CHEM Vertical Sump Pump Oil Change Once every eight hours of pump operation, perform visual inspection of oil and oil level at the constant level oiler. The first oil change should be carried out three weeks after commissioning; all further oil changes take place every six months.
  • Page 48 VSP CHEM Vertical Sump Pump DANGER Inadequate cleaning of debris settled on pump surfaces. Explosion hazard by electrostatic discharge!  When cleaning coated pump surfaces in atmospheres of Explosion group IIC, use suitable anti-static equipment. Locate the constant level oiler assembly and identify its three main components: the oil tank, the adjustable oil tank collar and the oil tank reservoir.

The proper direction is indicated by direction arrow on the pump casing.

  • Page 53: Startup

    VSP CHEM Vertical Sump Pump CAUTION Increased wear due to dry running. Damage to the pump set!  Never operate the pump set without liquid fill.  Never close the shut-off element in the suction line and/or supply line during pump operation.
  • Page 54 VSP CHEM Vertical Sump Pump Position of discharge valve on starting A high or medium head centrifugal pump operated at full speed with the discharge gate valve closed will require much less energy than when it is operated at its rated head and flow with the gate valve open.
  • Page 55 VSP CHEM Vertical Sump Pump MACHINE PROTECTION Formation of a potentially explosive atmosphere inside the pump. Explosion hazard!  When draining tanks take suitable measures to prevent dry running of the pump (e.g. fill level monitoring). WARNING Exposed coupling and shafting between pump and driver must be protected with coupling guard and/or shaft guard prior to pump start-up and operation.

  • Page 56: Operating Check

    VSP CHEM Vertical Sump Pump ATTENTION Only if your pump will operate submerged in a sump or well, the discharge valve may be left opened since installation and during the startup procedure. 7.2 OPERATING CHECK During the initial operating hours, the pump should be monitored constantly. It is thus possible to detect irregularities immediately and to take appropriate measures for their elimination (see SECTION ELEVEN - TROUBLESHOOTING CHART).
  • Page 57 VSP CHEM Vertical Sump Pump Ruhrpumpen recommends checking the pump constantly at regular intervals in order to detect problems early, in case they arise. The operational check routine must include at least the following points: WARNING Beware of freely rotating parts, when the pump is in operation there is a high risk of injury.
