## Long description

Replacement suction pump designed for sera external filter models Fil 250, Fil 250+UV and Fil 400+UV. This pump restores water flow and filtration performance in compatible filter housings by matching original mounting points and connecting to the existing tubing and power assembly. The unit is intended as a direct replacement part to maintain continuous circulation, mechanical and biological filtration in aquarium systems.
Advantages
The replacement pump reproduces the original pump’s form factor and connection points, which simplifies installation and reduces the need for adapter parts. It is engineered to re-establish the designed flow rates and pressure required for proper operation of the filter unit. Using an OEM-compatible pump helps avoid disruptions in water circulation and supports stable filtration performance without modifying the existing filter casing or plumbing.

Key specifications
 Form factor: compact external suction pump compatible with specified sera filter housings
 Connections: designed to fit original tubing and mounting points of compatible filters
 Function: restores water circulation for mechanical and biological filtration
 Compatibility: intended for use with sera Fil 250, Fil 250+UV and Fil 400+UV units
How to use
Before installation, disconnect the filter from mains power and drain the filter housing partially to prevent spills. Remove the filter cover and access the existing pump assembly, then disconnect the tubing from the old pump and unmount it from its bracket. Install the replacement pump by securing it to the original mounting points and reconnecting the tubing to the correct inlet and outlet. Reassemble the filter, refill as needed, and prime according to the filter manufacturer’s instructions if required. Reconnect power and observe operation to confirm restored flow and absence of leaks.
Usage recommendations
Inspect tubing and seals when replacing the pump; replace any worn hoses or O-rings to ensure leak-free operation. After installation, monitor water flow and noise for a short period to confirm the pump functions correctly. Follow aquarium safety practices: always disconnect power before service and avoid running the pump dry.
