Flojet 20033-005 Service Kit
The Flojet 20033-005 is a genuine Flojet service kit, part of the 20033 group of drive-side repair kits for Flojet diaphragm pumps.
Kits in this family cover the mechanical side of the pump — the components that turn motor rotation into diaphragm movement, rather than the wetted valve and diaphragm parts. That side of a pump fails differently from the wet end and on a different timescale. Wetted components are attacked by chemistry, heat and grit; drive components simply accumulate mechanical cycles until a bearing or a wearing surface reaches the end of its life. A pump can therefore have perfectly good valves and a badly worn drive, or the reverse, which is why the two are supplied as separate kits.
The symptoms of drive-side wear are mechanical rather than hydraulic: noise that rises with speed, roughness felt when the shaft is turned by hand, vibration, and a gradual loss of output as the stroke shortens. Because kit contents differ between models and revisions, confirm this part number against the parts breakdown for your specific pump before ordering — and if the label on the pump is no longer readable, send us what you can make out and we will work through it with you.
Key Features
- Genuine Flojet (Xylem) service kit — factory-matched components in one part number
- Covers the drive side of the pump rather than the wetted valve and diaphragm parts
- Addresses the mechanical wear that noise, vibration and a shortened stroke point to
- Matched, correct-revision parts — no cross-referencing individual numbers
- Restores a pump rather than replacing the whole unit
Applications
- Flojet diaphragm pump overhaul and repair
- Pumps showing mechanical noise, roughness or vibration

Frequently Asked Questions
Q: How do I tell drive-side wear from wet-end wear?
By the symptom. Noise, vibration and roughness point to the drive; loss of prime, cycling and failure to reach cut-out pressure point to the valves and diaphragm.
Q: Can both sides wear out at once?
They can, particularly on an older pump that has done a lot of hours. If the pump is apart anyway, inspecting both is far cheaper than doing the job twice.
Q: Is a kit better value than individual parts?
Usually. Individual ordering takes longer, risks missing a component, and often costs more by the time everything needed has been gathered.
Q: What information do you need to confirm the right kit?
The model number from the pump label, and a photograph of the pump if the label is worn. That is normally enough to identify the build and its correct kit.
Not sure this is the right part? Send us a Picture of the pump plate on your pump and the CLR Marine team will confirm this kit matches your build and tell you what it covers before you order.
