View productSHURflo 2088 & 2093 RV Pump Repair Kits — Parts Diagram
SHURflo 2088 and 2093 diaphragm pumps use several different internal repair kits. A valve assembly or drive assembly that fits one 2088 model may not fit another, even when the outer pump housing looks similar. Use the full model number on the pump label to match the manufacturer's replacement parts before opening the pump.

The 94-237-00 check valve is also listed by Pentair for the pump models above. A replacement upper housing is not a complete pump head, and the 94-238-03 and 94-238-04 drive assemblies are different repair kits.
Locate each component on the exploded drawing
1 — Upper housing
Contains the pump's pressure-switch housing and connection ports.
2 — Valve assembly
Controls flow through the pump chambers.
3 — Drive assembly
Uses the diaphragm drive to move water through the pump.
4 — Motor
Drives the assembly and varies by pump model and voltage.
5 — Pump-head kit
A model-specific combined assembly; not the same as just the outer housing.
Before ordering repair parts
- Read the entire pump model from its identification plate, including the characters after the last hyphen.
- Identify the affected component using the exploded drawing, then match its part number to the same model row.
- Disconnect power, shut off the water supply and release plumbing pressure before service.
- Replace worn seals or components as instructed, reconnect the plumbing and check for leaks before normal operation.
