SHURflo Pump Parts Diagrams by Model

Find the service diagram for your SHURflo freshwater or waste pump by its model number. Each guide covers the identified pump family and links to related repair parts available on NewRVParts. The pump's full model suffix, voltage, and service assembly number matter when selecting a replacement.

Waste pumps and plumbing accessories

Use the pump and plumbing accessory diagrams for their own part numbers, rather than treating them as freshwater-pump repair kits.

How to choose a SHURflo pump part

Locate the complete model number on your existing pump label, including the suffix and operating voltage. Open that model's reference, identify the service assembly, and compare its part number with the linked listing. For freshwater pumps, distinguish the pump head, valve assembly, diaphragm, check valve and pressure switch; for a waste macerator, consult its separate impeller and pump service reference.

Model numbers are the starting point. A part used with one SHURflo pump version is not automatically interchangeable with another model, voltage or production revision.
