Compatibility / Fitment Guide
| Check | Required specification | Decision |
|---|---|---|
| Supply | 24V DC system within approximately 20–32V | Use correctly rated cable, switching and over-current protection. |
| Hydraulic arrangement | Flooded inlet / non-self-priming circulation loop | Mount below liquid level or otherwise maintain a fully flooded inlet. |
| Fluid | Fresh water or water/glycol mixture up to 60% glycol | Not specified for fuel, oil, sewage or abrasive liquids. |
| Ports | 38mm / 1-1/2in hose tails (D38 configuration) | Do not order hose/fittings from the model name alone; verify the physical SKU/label. |
| Performance | Required flow checked against the pump curve at actual system head | 90L/min is quoted at only 0.1 bar and will decrease with restriction. |
Not suitable for: self-priming or bilge duty, fuel/oil/sewage, dry suction lift, 12V supply, or designs based on 90L/min without a head-loss calculation.

Frequently Asked Questions
Is it self-priming?
No. It is a centrifugal circulation pump and requires a flooded inlet.
Will it always deliver 90L/min?
No. That figure is at 0.1 bar; actual flow depends on system head and restriction.
Can it circulate antifreeze?
It is specified for water/glycol mixtures up to 60% glycol.
Can it replace a 12V CM90?
No. This listing is the 24V variant; voltage and exact port configuration must match.
Before ordering: Verify the 10-24898-02 item label against the current D38 specification, 24V supply and 38mm ports, fluid/glycol concentration, flooded inlet and duty point on the pump curve.
