Product Description

Product Description

General description

Product description

The 3171 is a vertical submerged bearing sump and process pump.

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

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 spin-balanced (single plane) to ISO G6.3. 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.

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 precisionground, 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.

12	Model 3171 Installation, Operation, and Maintenance Manual

Product Description (Continued)

Bearings

The thrust bearing is a grease-lubed, double-row, angular contact ball bearing. 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 grease seal	This seal is used below the thrust bearing in order to contain the
	grease and exclude any possible contamination.
Carbon Teflon® 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.

Nameplate information

Important information for ordering

Every pump has a nameplate that provides information about the pump. The nameplate is located on the motor support.

When you order spare parts, identify this pump information:

•Model

•Size

•Serial number

•Item numbers of the required parts
