Replacement impeller 113532 is now obsolete. If you have a SEH-50X prior to 2009 which calls for this impeller then use 120962 ALONG with a new Volute 0120933 (replaces 0114640) also

the 0120962 impeller is the official replacement for the 0113532, but there is a specific condition regarding the volute.

Compatibility & Technical Specs

The 0120962 is the modern "New Type" impeller for the Koshin SEH-50X (2-inch) pump series.

• Interchangeability: It replaces the obsolete part number 0113532.

• The "Volute" Rule: If you are upgrading from the very old version (pre-2009) that used the 0113532 impeller, you must use it in combination with the 0120933 Volute Casing.

• Vane Difference: The older 0113532 often had a different vane configuration (3 vanes vs. the 0120962's updated design). They are sold as a "Kit" (Impeller + Volute) because the clearances within the pump casing changed.

Rechangeable Models

The 0120962 impeller and 0120933 volute combination is commonly used across several Koshin 2" (50mm) pump models. You will find these parts in:

Export to Sheets

Warning: Do not confuse these with the KTH series (Trash Pumps). Trash pump impellers (like part 0115447) are much larger and are not interchangeable with the SEH series.

Summary Checklist for Ordering

• Check your Volute: If your current volute is part 0114640, you must replace it with 0120933 to use the new impeller.

• Part Number Stamping: Look at your old impeller; Koshin often stamps a 7-9 digit number on the casting. If it says 113532, the 0120962 is your only modern option.
