PUMP DESCRIPTION

The model CV3171 is a vertical vortex, recessed open impeller pump that generates pressure head by creating a vortex in the casing. Use of a recessed impeller allows for solids, entrained air, or shear sensitive liquid handling.

The model is based on 1 power end and 8 hydraulic pump sizes:

2X2-8 2X2-10 3X3-10 2X3-13 3X4-13

LF 1x1.5-8 LF 1x2-10 LF 1.5x3-13

Casing: The casing of the CV3171 is concentric volute and available with optional connections for venting, flushing and solids clean out.

Impeller: The impeller of the CV3171 is fully open, has curved vanes, and is threaded to the shaft. The LF sizes have straight radial vanes and are threaded to the shaft. The threads are sealed from the pumpage by a Teflon O-ring.

Strainer: The strainer is a basket type with openings sized to prevent the entrance of large solids commonly ending up in open sumps.

Power End: The power end of this pump is identical to the 3171 power end. It consists of the motor, coupling, motor mount, support plate, double-row ball thrust bearing, shaft, column pipe header, steady bearings, and column pipe extension.

Bearings: The thrust bearing is a grease or oil-mist lubricated double row angular contact ball bearing. It is shouldered and locked to the shaft and the housing enabling it to carry all of the thrust loads and some of the radial load. All fits are precision machined to industry standards. The steady bearings are press fit sleeve bearings. Fits are designed for optimum life under all operating conditions.

Seals: The standard CV3171 has three seals.

 An upper labyrinth seal is used to exclude dirt

and water from the thrust bearing.

 A lower grease seal is used below the thrust

bearing to contain the grease and exclude any possible contamination.

 A carbon Teflon casing collar is installed

immediately behind the impeller in the adapter to minimize recirculation back to the sump, thereby maximizing hydraulic efficiency.

Discharge Elbow: The discharge elbow is a short radius elbow that provides compact size and minimum profile.

Direction of Rotation: Clockwise (right hand) as viewed from the driver, looking at the pump shaft.

Maximum Solids Size: For CV3171 pumps, the max. solids size is 1.875 in. for 2” discharge and

2.875 in. for 3” discharge. Refer to the current pump curve for maximum solids capabilities.

12 CV#3171#IOM#05/11#

Steady Bearings:

1. Carbon and Carbon Filled Teflon - These bearings are chemically inert in most liquids and can be used in liquids up to the temperature limits of the pump. They should not be used in liquids containing abrasive solids. Clear flush from the support plate is required.

2. Fluted Rubber or Viton - These bearings consist of fluted rubber or Viton contained within a metal shell. Clear water from an outside source, 1 to 2 GPM, is required to each bearing housing. They are ideally suited for liquids containing abrasive solids but are limited to 160°F temperature liquid. Corrosion resistant shafting is required.

3. Metallic Bearing - Bronze steady bearings are available and must be grease lubricated. Lack of lubrication can lead to galling and eventual seizing. It becomes extremely difficult to keep enough grease in the housing when handling hot liquids, caustic solutions or solvents. Unless an adequate maintenance program exists, it is recommended that a self-lubricating bearing such as carbon be used in place of the metallic bearing.

4. Sealed Bearings - Recommended for abrasive liquids where no outside flush is available. The carbon bearing is sealed within the housing by two lip seals and filled by grease via pressure lubricator located above the support plate. The pressure cup must be kept full of grease. The control screw on the pressure cup should be wide open to start and then controlled by usage.

NAMEPLATE INFORMATION

Pump Nameplate – Every pump has a Goulds nameplate that provides information about the pump. The tag is

located on the motor support. When ordering spare parts you will need to identify pump model, size, serial number, and the item number of required parts. Information can be found in this manual. Part numbers can also be found on the Repair Data Sheet supplied with the original pump data package.

RECEIVING THE PUMP

Inspect the pump as soon as it is received. Carefully check that everything is in good order. Make notes of damaged or missing items on the receipt and freight bill. File any claims with the transportation company as soon as possible.

STORAGE REQUIREMENTS

Short Term: (Less than 6 months) Goulds normal

packaging is via a skid. It is designed to protect the pump during shipping only. Upon receipt, store in a covered and dry location.

Long Term: (More than 6 months) Preservative treatment of bearings and machined surfaces is required. Rotate the shaft several times every three months making sure that the shaft does not stop in the same place as it may sag. Refer to driver and coupling manufacturers for their recommended long-term storage procedures. Store in covered dry location.

NOTE: Long term storage treatment can be purchased with the initial pump order.

HANDLING

WARNING

Pump and components are heavy. Failure to

properly lift and support equipment could result in serious physical injury or damage to pumps. Steel toe shoes must be worn at all times.

Use care when moving pumps. Lifting equipment must be able to adequately support the entire assembly. Position the pump where it can be handled without dragging the casing on the ground or moving the lifting equipment while the pump is off the ground. Use the lifting lugs supplied with the unit and suitable slings to lift the entire pump to a vertical position (Figure 2). A tag line should be attached to the casing end to prevent the pump from swinging and possibly causing damage or injury. Lower the unit into the sump. The motor should then be hoisted into position using the lifting lugs on the motor and a suitable sling (Figure 3).

INSPECTION

Equipment that will operate in a potentially explosive

environment must be installed in accordance with the following instructions.

All equipment being installed must be properly grounded to

prevent unexpected static electric discharge. If not, a static electric discharge may occur when the pump is drained and disassembled for maintenance purposes.

Service temperature in an

ATEX classified environment

is limited by Table 1 in the ATEX identification section.

1. Remove all equipment from shipping

containers.

2. Completely clean the underside of the

support plate, and both sides of the optional pit cover (if supplied).

3. Remove any grease from machined

surfaces if applicable.

CAUTION Remove plastic shipping plugs from the vent holes in the head

column and casing. Refer to Figure 4 for locations.

Figure#4#

16 CV#3171#IOM#05/11#

SITE/FOUNDATION

The pump should be located where there is adequate space for installation, operation, maintenance, and inspection. Make sure there is adequate overhead clearance for installing and removing the pump. There should be at least 1/2” clearance between the sides of the pump and any portion of the pit.

Vertical sump pumps are normally bolted to a concrete sump or steel tank. The supporting structure must provide a permanent rigid support

for the pumping unit(s) to eliminate any possible vibration. Support plates and/or pit covers are not normally grouted in place. The location and size of the mounting bolt holes are shown on the pump outline drawing provided with the pump data package. If anchor bolts are to be poured into the concrete, it is recommended that a sleeve type as shown in Figure 5 be used to allow for adjustment.

WHEN PIT COVER IS USED

If access to the bottom of the pit cover is not possible during the installation process, the pump (less motor), support plate and pit cover must be assembled and installed as a unit.

1. The pit cover must be installed level to insure that the pump remains plumb when installed.

2. Carefully lower pit cover foundation bolts.

3. Using as long a level as practical, level the pit cover in all directions with shims or wedges.

4. Hand tighten the anchor bolts, check the level and re-shim if necessary.

5. Tighten all anchor bolts in a star pattern to avoid distorting the support plate.

6. If access to the bottom side is possible, carefully lower the pump and support plate onto the pit cover.

7. Install all bolts finger tight.

8. Check level on support plate and shim if necessary.

9. Tighten all bolts in a star pattern to avoid distorting the support plate.

Vapor Proof Option

The vapor proof option includes machined, gasketed fits between the support plate/pit cover and the pit cover/foundation. These gaskets must be installed to insure emissions performance. The pit cover should be bolted to a metal sole plate with a machined surface to insure an airtight seal.
