  • Page 6: Introduction

    The pump has been designed for the pumping conditions specified in the customer’s order. Flowserve must be consulted prior to any significant change of conditions.

  • Page 7: Construction

    1.3 CONSTRUCTION The SVCN 7 pump has these basic design features: it is centrifugal and single suction; it has a cantilever rotor and a centerline-supported, radially split case which is either single- or double- voluted. Its major components are case, head, rotor, ball bearings, bearing housing, and mechanical seal or packing.

  • Page 8: Bearing Lubrication

    Cartridge seals may also used. 1.3.7 HEAD The head on the SVCN 7 pump has a packing gland or a seal plate and it is installed from outside the head. Only packing can be replaced without disassembling the pump. The head with packing gland incorporates a passageway and tapped boss for piping a lubricant to the lantern ring.

  • Page 9: Mechanical Seal

    Flowserve prefers to use a lantern ring with packing in order to circulate liquid from an external source around the packing, removing some of the packing-generated heat. The packing box bushing is usually pressed into the head from the outside but it may be designed for installation from the inside.

    (if provided), which are usually preserved and packed in a box attached to the skid. If any damage is indicated and/or parts are missing, notify the carrier and the nearest Flowserve office immediately. Upon conclusion of the receipt inspection, the shipping enclosure should be resealed for storage or transport.

During extended periods of storage prior to installation, precautions must be taken to protect the pump from deterioration.

  • Page 12: Preparation For Storage

    Inspect all painted surfaces. If necessary, touch-up areas where paint has been chipped or scraped. External surfaces are usually painted with a paint that combines a primer with a finish coat. See the contract specification for any non-standard paint requirements, or contact your nearest Flowserve office.

  • Page 13: Six Months Prior To Installation

    Upon completion of the inspection the Flowserve representative shall submit a report to the purchaser, and to the FLOWSERVE Manager of Customer Service, stating in detail the results of the inspection. 1.7.3.2 One Month Prior to Installation One month prior to installation of the equipment, a Flowserve representative is to be employed to conduct a final inspection.

    This is especially true if the changes reduce the pressure at the suction or if the liquid temperature is increased. When installing piping, Flowserve recommends: 1. that as the line is erected, a swab fitting the entire cross section of the pipe be pulled through each section to assure the removal of scale or other foreign material;...

  • Page 17: Bypass Line

    SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE The Flowserve standard for suction strainers consists of a conical shaped steel plate. The plate has 1/16” perforations and is of sufficient size and thickness for the required flow. The open area of the strainer should have a minimum of a 3 to 1 ratio to the area of the pump suction (see Figure 2-1 Typical Suction Strainer below).

  • Page 19 SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE Prepare sufficient steel blocks of at least 1 in. (25 mm) thickness to be placed below each baseplate jacking screw furnished with the baseplate. The purpose of the plate is to spread the load of the screw without crushing the concrete below, and to provide a minimum of 1 in.

    When the grout is thoroughly hardened, remove the dam. If the leveling wedges are removed, fill the holes they leave with grout. 2.2 SHAFT ALIGNMENT Shaft alignment is critical to good performance of your pump.

  • Page 30: Operation

    The pump is designed to deliver rated capacity and rated head for a liquid with a particular viscosity. When contemplating operation at some viscosity other than for which the pump was originally designed and/or applied, the changed conditions should be referred to Flowserve for our recommendations.

  • Page 31: Minimum Continuous Stable Flow

    SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE 3.1.5 MINIMUM CONTINUOUS STABLE FLOW The minimum continuous stable flow for this pump is listed on your pump data sheet. Figure 3-1 Minimum Flow Correction Factor for NPSHA Margin 1.20 1.00 Percent of Design R.P.M.

    SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE Total Minimum Flow Minimum Flow + (Total No. Pumps - 1) × (Strong Pump Flow) of Pumps in System of Weakest Pump Sample: (see Figure 3-3) 1. Assume the minimum flow for a single pump is 27 GPM.

  • Page 34: Lubrication Specifications

    SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE pure mist systems, ensure that the pure mist system is installed on the pump bearing housing, and is operating in accordance with the manufacturer’s instructions. No further preparation is necessary. 3.3.1 LUBRICATION SPECIFICATIONS The ideal bearing lubricant is mineral oil, preferably of the turbine type. It should not contain free acid, chlorine sulfur or more than a trace of free alkali.

  • Page 35: Bearing Housing Preparation

    SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE 3.3.2 BEARING HOUSING PREPARATION Before filling the bearing housing reservoir, flush out the housing thoroughly with safety solvent and a leading grade of flushing oil, compatible with the lubricating oil that will be used.

  • Page 36: Replenishment

    SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE 3.3.5 REPLENISHMENT Replenish the oil in the oiler as required. More frequent replenishment at high temperatures may be required. 3.3.6 OIL CHANGE Frequency of oil change is dependent on pump service and environmental conditions. As a general guide, the oil in the bearing housing should be changed after the first 500 hours of operation, and again every six months after that.

  • Page 37: Initial Start Up Procedure

    SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE 2. Ensure the pump and piping is clean. Before placing the pump in operation, the piping should be thoroughly back flushed to remove any foreign matter, which may have accumulated during installation. 3. Install the suction strainer (see paragraph 2.1.2.1, “Suction Strainer”, on page 2-1).

  • Page 38: Normal Start-Up

    SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE CAUTION Before starting or while operating the pump, the case and suction line must be completely filled with the liquid being pumped. The rotating parts depend on this liquid for lubrication and the pump may seize if operated without liquid.

  • Page 39: Operating Checks

    Operation at low flows results in pump horsepower heating the liquid. A bypass may be required to prevent vaporization and subsequent pump damage. Refer to your local Flowserve office to determine if a bypass is required. Mechanical damage may result from continuous operation at flows less than the specified minimum continuous stable flow.

  • Page 40: Securing The Pump

    SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE WARNING Operation of the unit without correct lubrication can result in overheating of the bearings, bearing failures, pump seizures and actual breakup of the equipment exposing operating personnel to physical injury. 5. Check oil level in bearing housing.

  • Page 44: Maintenance

    The SVCN 7 pump incorporates a pull-out element design, so it is not necessary to remove the case, detach the suction or discharge piping, or disturb the driver, in order to perform any regular maintenance on the pump.

  • Page 45: Packing

    SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE 1. Tag driver controls in the OFF position. 2. Isolate pump from the suction and discharge system and any other auxiliary systems. 3.
