Compatibility / Fitment Guide
| Check | Required specification | Decision |
|---|---|---|
| Supply | 12V DC circuit sized for motor start and running current | Do not connect this 12V motor to a 24V supply. |
| Plumbing | 3/4in BSP connections with reinforced hose/pipe and leak-free fittings | Use full-bore lines and minimise restrictions for the required flow. |
| Fluid | Bilge/deck water, circulation water, oil or diesel transfer as specified | Fluid compatibility and temperature must suit the impeller and seals. |
| Suction | Self-priming installation with accessible strainer and service path | Do not run the flexible impeller dry; prime/wet and service per SPX instructions. |
| Duty | Commercial service with correctly rated switch, fuse and wiring | Flow depends on head, hose length, viscosity and system restriction. |
Not suitable for: 24V supply, petrol/gasoline or other volatile liquids without explicit approval, potable-water duty without suitability confirmation, abrasive solids or deliberate dry running.

Frequently Asked Questions
Is this the 12V or 24V pump?
This listing and SKU 10-24188-1 are for 12V DC.
Will it always deliver 55L/min?
No. That is the published maximum; actual flow falls with head, restriction and fluid viscosity.
Can it transfer petrol?
Do not use it for petrol or volatile fuels unless SPX explicitly approves the exact installation.
Can it run dry?
Flexible impellers can be damaged by dry running. Prime/wet the pump and follow the service instructions.
Before ordering: Verify voltage, fluid compatibility, port thread, flow at system head, cable/fuse sizing and mounting space.
