Goulds 3700 Replacement Pumps & Parts
ACCA Pumps supplies private-label replacement pumps and aftermarket parts for Goulds 3700 API process pump applications. The 3700 is an API 610 / ISO 13709 OH2 overhung process-pump design used in refinery, petrochemical, chemical and other demanding process services.
Complete 3700 Pumps and Replacement Components
Supply scope can include complete pump assemblies and individual components such as casings, impellers, wear rings, shafts, shaft sleeves, seal chambers, bearing housings, radial and thrust bearings, gaskets and other power-end components. Configuration and material are verified against the specific pump before quotation.
Complete Pumps
Engineered replacement pump assemblies matched to hydraulic size, duty, metallurgy, sealing arrangement and installed configuration.
Wet-End Components
Casings, impellers, wear rings, seal chambers and related process-end components for supported 3700 configurations.
Power-End Components
Shafts, sleeves, bearing housings, radial and thrust bearings, oil-system and rotating components.
Cross-Reference Support
Identification by complete pump size, power-end designation, serial number, material and existing reference part number.
3700 Power-End Families
Use the power-end designation as an identification aid together with the complete hydraulic size and construction. It is not, by itself, a statement of component interchangeability.
SA / SX
Verify complete pump size, serial number, construction and material before selecting components.
MA / MX
Identify the hydraulic size and exact power-end construction for replacement-parts review.
LA / LX
Use the designation with pump size, serial number and construction details for cross-reference.
XLA / XLX
Confirm the complete installed configuration before quoting rotating or power-end components.
XXL
Large power-end configurations require complete size and construction identification.
3700 Hydraulic Size and Power-End Identification
The 3700 family spans numerous hydraulic sizes and multiple power-end arrangements. Common identification designations include SA, SX, MA, MX, LA/LX, XLA/XLX and XXL. These designations should be treated as identification data rather than a blanket statement of interchangeability. Pump size, serial number, original part number, material and construction details should be confirmed for each RFQ.
| Identification family | How ACCA uses it | Verify before quotation |
|---|---|---|
| SA / SX | Power-end identification for applicable 3700 configurations | Complete pump size, serial number, edition/construction and material |
| MA / MX | Power-end identification for applicable 3700 configurations | Complete pump size, serial number, edition/construction and material |
| LA / LX | Power-end identification for applicable 3700 configurations | Complete pump size, serial number, edition/construction and material |
| XLA / XLX | Power-end identification for applicable 3700 configurations | Complete pump size, serial number, edition/construction and material |
| XXL | Large power-end identification where applicable | Complete pump size, serial number, edition/construction and material |
Important: the power-end designation alone is not sufficient to establish component interchangeability. ACCA matches the identification data to the specific hydraulic size and construction before quoting.
3700 Size Families
Documented 3700 configurations include sizes such as 1 x 2-7, 1 x 2-9N, 1½ x 3-9, 1½ x 3-11, 1½ x 3-11N, 2 x 4-11, 4 x 6-11, 4 x 6-11N, 4 x 6-13, 6 x 8-13A, 3 x 4-16L, 4 x 6-16N and 10 x 12-21, among many additional hydraulic configurations. ACCA verifies the exact size and construction before selecting replacement components.
3700 Replacement Parts by Pump Size
ACCA’s Goulds cross-reference contains extensive 3700 component data across multiple hydraulic sizes and constructions. Representative records include the following. Final selection must be verified against the complete pump identification, material and construction.

Part-number note: Reference numbers are used for identification and cross-reference. ACCA private-label part numbers may use the corresponding reference number with the ACCA A- prefix where applicable. Material suffixes and construction details matter and should not be inferred from the base number alone.

Parts Identification and Cross Reference
For complete equipment, review ACCA’s industrial centrifugal replacement pumps.
For parts identification, provide the Goulds model, complete pump size, serial number, part number if available, material of construction, seal arrangement and service conditions. Photos of the nameplate and removed component are useful when the original identification is incomplete.
