Product Description
Model API 3171 Installation, Operation, and Maintenance Manual12
Product Description
General description
Product description
The Model API 3171 is a vertical submerged bearing sump and process pump that meets the requirements of the 10th and 11th editions of API Standard 610 (ISO 13709).
This model is based on three bearing frames with 17 hydraulic sizes. The S/ST group has identical bearings with a slightly different shaft on the impeller end for the S and ST. The M/MT group is identical in all aspects for the power end. However, the liquid end of the MT is common with the S group except that the MT is modified to accept a larger shaft. There are two MT sizes that are common with the S/ST group.
This table shows the number of hydraulic sizes available for each drive-unit size group. Note that each pump has a choice of two different discharge pipes which results in four combinations.
Drive-unit size group Number of hydraulic sizes
S/ST 9 M/MT 8 L 2
WARNING:
Use of equipment unsuitable for the environment can pose risks of ignition and/or explosion. Ensure that the code classifications on the pump are compatible with the specific environment in which the equipment is to be installed. If they are not compatible, do not operate the equipment and contact an ITT representative before proceeding.
Casing
The casing has these features:
• A tangential discharge
• Is self-venting
• Has an integral bearing retainer
• Is precision-bored in order to ensure permanent alignment between the column casing, suction cover, and bearing
Impeller
The impeller is fully open, keyed to the shaft, and held in place by a self-locking capscrew in order to ensure positive locking and prevent damage from reverse rotation. Impellers are spin­balanced (single plane) to ISO G2.5. The impeller is provided with back vanes in order to reduce the axial thrust and prevent the entrance of solids.
The impellers on this pump do not meet the dimensional requirements for dynamic balancing.
Strainer
The flat plate strainer is designed to maximize draw-down in a given sump depth. Openings are sized to prevent the entrance of large solids that are commonly found in open sumps.
Discharge elbow
The discharge elbow is designed to allow the pump to fit into the smallest possible opening. A threaded connection to the discharge pipe allows the pipe to be changed without removing the pump from the sump.
Product Description
Model API 3171 Installation, Operation, and Maintenance Manual 13
Column pipe
The column pipe has flanged connections that are machined in order to ensure true parallelism and to maintain steady bearings concentric with the shaft.
Shaft
The standard design uses a one-piece shaft in order to ensure accurate alignment. The shaft is precision-ground, polished, and straightened to keep vibration and deflection to a minimum. Standard bearing spans keep the shaft well below first critical speed for all sizes.
Bearings
The thrust bearing is grease- or oil-mist-lubricated and consists of a pair of single-row, angular contact ball bearings arranged back-to back. The bearing is shouldered and locked to the shaft and housing. This enables the bearing 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
This pump has three seals:
Seal type Description
Upper labyrinth seal This seal is used to exclude dirt and water from the thrust
bearing.
Lower labyrinth seal This seal is used below the thrust bearing in order to contain the
grease and exclude any possible contamination.
Carbon PTFE casing collar This seal is installed immediately behind the impeller in the
casing in order to minimize recirculation back to the sump and maximize hydraulic efficiency.
Motor support
Motor supports are cast construction and precision-machined in order to maintain proper alignment between the motor and pump shaft with minimal shimming. Motor supports are designed for vertical C-face motors as standard. P-base supports and IEC adapters are available upon request.
Direction of rotation
The shaft rotates clockwise when you look down on the pump shaft.
Enclosed lineshaft
The enclosed lineshaft design lends itself well for applications where abrasives are present in the pumped fluid, or when a bearing lubricant other than the pumped fluid is required.
Lubrication system
CAUTION:
The fluid must run continuously to ensure flow out of the column at all times. If the flush stops, the fluid in the sump can back up into the column. This contaminates the bearings.
The main feature of this modified design is a positive lubrication system for all bearings. This design requires a minimum of lubrication fluid due to the bushing located at the bottom of the column adapter housing directly above the impeller.
Acceptable leak rates
Leaks (flows) across the bushing for certain pressure differentials are shown in this table. Higher pressures will result in higher leaks.
Pressure differential (PSI) Approximate leak rate (GPM)
3.0 0.33
5.0 0.44

Protect the unit from weather and water damage due to rain, flooding, and freez­ing temperatures.
This is applicable if nothing else is specified.
Do not install and operate the equipment in closed systems unless the system is constructed with properly-sized safety devices and control devices.
Acceptable devices:
• Pressure relief valves
• Compression tanks
• Pressure controls
• Temperature controls
• Flow controls
If the system does not include these devices, consult the engineer or architect in charge before you operate the pump.
Take into consideration the occurrence of unwanted noise and vibration.
The best pump location for noise and vibration absorption is on a concrete floor with subsoil underneath.
Concrete foundation requirements
Requirements
Make sure that you meet these requirements when you prepare the pump foundation:
• The foundation must be able to absorb any vibration.
• The foundation must be able to form a permanent and rigid support for the pumping unit.
• The foundation must be of adequate strength in order to support the complete weight of the pump and driver, plus the weight of the liquid that passes through it.
• There should be at least 12.7 mm | 0.5 in. clearance between the sides of the pump and any portion of the pit.
Typical installation
A typical installation has these characteristics:
• Bolts with a pipe sleeve that is two and a half times the size of the bolt diameter embedded in the concrete
• Properly sized
• Located in accordance with the dimensions given in the example drawing
• Enough space inside the pipe sleeves to allow the final position of the foundation bolts to align with the holes in the sub-base flange
