Goulds 3196 Pattern Pump Parts
YSM manufactures aftermarket casings, impellers, stuffing box covers and seal chambers, frame adapters, bearing frames, bearing housings, frame feet, shafts and shaft sleeves for pumps built to the Goulds 3196 pattern under ASME B73.1. The tables list each part by pump size and frame with the YSM reference number and the OEM part number it corresponds to. The OEM number identifies the part to be matched; the fit is confirmed against your pump nameplate and drawing before an order is accepted.
Identify the installed pump first
Three items on the nameplate decide which parts fit: the size designation (discharge × suction − nominal impeller diameter, such as 3×4-13: 3 in discharge, 4 in suction), the frame (STX, MTX, LTX or XLTX, or the i-FRAME equivalent) and the serial number. If the nameplate is missing, photographs of the casing flanges and the power end plus the casting numbers on the casing usually allow the size and frame to be established. The G196 series page describes the frames and sizes; the G196 vs Goulds 3196 interchange guide explains which dimensions ASME B73.1 fixes and which YSM confirms from drawings.
| Frame in the tables | i-FRAME name | Pump sizes on this page |
|---|---|---|
| STX | STi | 1×1.5-6, 1.5×3-6, 2×3-6, 1×1.5-8, 1.5×3-8 and the 1×1.5-8LF low-flow size |
| MTX / LTX | MTi / LTi | 8 in, 10 in and 13 in sizes from 2×3-8 to 4×6-13, including 3×4-8G, 3×4-10H, 4×6-10H and the LF low-flow sizes. MTX and LTX share casing, impeller and cover; the power-end parts differ. |
| XLTX | XLT-i | 6×8-13, 8×10-13, 6×8-15, 8×10-15, 8×10-15G |
The frame name and the size designation (for example 3×4-13) are both on the nameplate. Send the serial number as well; it lets us check the build generation before quoting.
Parts by item number and material
A YSM reference ends in a suffix that names the part: 100 casing, 3 impeller, 106 cover, 108 adapter, 119 bearing frame, 201 bearing housing, 109 foot, 105 shaft, 177 sleeve. The letters before the suffix identify the pump size or frame, so the casing and impeller of one size share a prefix (GAU100 and GAU3 are the 3×4-13 casing and impeller). The OEM item numbers are those of the 3196 sectional parts list.
| Part | OEM item no. | YSM ref. suffix | Materials offered | Confirmed before order |
|---|---|---|---|---|
| Casing | 100 | 100 | WCB carbon steel, CF8M (316SS), CD4MCu duplex, CN7M (Alloy 20), Monel, Nickel, Hastelloy B and C, Titanium, Zirconium alloy | Size designation, flange rating and face, drain and gauge tappings |
| Impeller (open) | 101 | 3 | CF8M, CD4MCu, CN7M (Alloy 20), Monel, Nickel, Hastelloy B and C, Titanium, Zirconium alloy | Size, current trim diameter or duty point, impeller thread from the shaft |
| Stuffing box cover (packed box) | 184 | 106 | WCB, CF8M, CD4MCu, CN7M, Monel, Nickel, Hastelloy, Titanium | Frame and impeller diameter, gland bolting |

| Bearing housing | 134 | 201 | Per YSM drawing, stated at quotation | Frame; bearing arrangement fitted |
| Frame foot | 241 | 109 | Per YSM drawing, stated at quotation | Frame and impeller diameter |
| Shaft | 122 | 105, 105S | SAE 4140, 316SS, CN7M, Monel, Nickel, Hastelloy, Titanium | Whether a shaft sleeve is fitted (selects the 105 or 105S version); coupling-end diameter and keyway; impeller thread |
| Shaft sleeve | 126 | 177 | 316SS, CN7M, Monel, Nickel, Hastelloy, Titanium | Frame; seal setting dimension |
Alloys not listed for a part are quoted on request. Higher alloys are cast on the same patterns as the CF8M part, so the dimensions do not change with the grade. Material certificates, spectrometer analysis and a dimensional inspection report can be supplied with the order.

Casings and impellers by pump size
Casing and impeller references are specific to the pump size. Read the size from the nameplate, then take the two references from that row. The impeller reference is for the standard diameter; state the trim diameter, or the duty point, if the installed impeller has been cut down.
| Pump size | Casing · YSM ref. | Casing · OEM no. | Impeller · YSM ref. | Impeller · OEM no. |

The 8×10-15G casing is the version with the larger nozzles.
Stuffing box covers and seal chambers
The cover is selected by frame and impeller diameter, not by pump size: one reference serves all 13 in MTX and LTX pumps, for example. Tell us which chamber the pump runs today (packed box, standard bore, large bore or taper bore seal chamber) and the gland bolting, and we confirm the variant before quoting.

The standard reference is the packed stuffing box cover (item 184). Variants B and F are seal chamber designs for mechanical seals (item 184M); the chamber bore of each is confirmed at quotation.
Power-end parts, shafts and sleeves
Power-end parts are selected by frame. For shafts, state whether the pump runs a sleeve or a solid shaft, and send the coupling-end diameter and keyway if the coupling is to be reused. Bearings, oil seals and labyrinth isolators are bought-out items and can be included with the order.

What we confirm before an order
From your side
- Nameplate photo: model, size designation, frame, serial number
- The part and quantity, with the OEM item or part number if the parts list is available
- Material of the installed part, or the liquid, concentration and temperature if the material is to be reviewed
- For impellers: trim diameter or the duty point (flow and head)
- For covers: seal chamber type and gland bolting
From YSM
- The YSM reference matched to your nameplate data, with the interfaces checked listed in the quotation
- Material grade and the documents to be supplied: material certificate, spectrometer analysis, dimensional inspection report, balance report for impellers, hydrostatic test for casings
- Inspection scope, including factory witness or third-party inspection (SGS, BV, TÜV) where required
- Packing and Incoterms as agreed in the quotation
Anything unknown can be stated as unknown; a marked gap is reviewed, a silent one is not. The pre-replacement checklist lists the same items in order, and the OEM number finder on the parts hub searches every reference on this page by OEM number.
Frequently Asked Questions
Are these Goulds parts?
No. They are aftermarket parts manufactured by YSM to the Goulds 3196 pattern. OEM part numbers appear in the tables only to identify which part a YSM reference corresponds to. YSM is not affiliated with ITT Goulds Pumps.
How do you confirm that a part will fit my pump?
From the nameplate: the size designation, frame and serial number select the row in the tables. We then confirm the interfaces that matter for that part (casing register and bolt pattern, impeller thread and hub, seal chamber bore and gland bolting, shaft coupling end) against our drawings and, where you can supply them, your drawing or the removed part. The quotation lists what was checked.
My nameplate shows an i-FRAME designation such as MTi. Which frame row applies?
The tables use the X-series frame names. The frame table at the top lists the i-FRAME name that belongs to each group, so an MTi nameplate is read against the MTX rows. Send the nameplate anyway; we confirm the power-end parts against the frame generation before quoting.
Which materials can you supply?
Wet-end parts in CF8M (316SS), CD4MCu duplex, CN7M (Alloy 20), Monel, Nickel, Hastelloy B and C, Titanium and Zirconium alloy; casings also in WCB carbon steel. Bearing frames in cast iron (ductile iron on STX), adapters in ductile iron, shafts in SAE 4140 or 316SS with sleeves in the wet-end alloy. Alloy verification by spectrometer is standard; material certificates are supplied on request.
Can you supply a size that is not in the tables?
The tables list the sizes that have a YSM reference today. For another 3196-pattern size send the nameplate and, if possible, a drawing or the removed part; the part is then quoted from a reviewed drawing. Obsolete or undocumented parts can be reverse engineered from the removed part. Selected numbers also have a page of their own in the pump part number lookup, with the part, its size and the other positions for that size.
Can you supply the impeller cut to my trim diameter?
Yes. State the trim diameter marked on the impeller or nameplate, or send the duty point (flow and head) and we select the diameter. Every impeller is dynamically balanced before shipment.
Send the Nameplate. Get the Matching Parts List.
Send the pump nameplate, the part and quantity, and the OEM part number if you have it. The YSM references and the interfaces we check are confirmed before order.
