Description
Blue Lagoon replacement pump head for Dosatech B290065
The Blue Lagoon replacement pump head for Dosatech (reference B290065) is the complete peristaltic head assembly for the Blue Lagoon Dosatech dosing pump.
It includes the pump housing with rollers and integrated dosing hose so you can restore dosing performance quickly when the original head is worn or damaged.
Main features of the Blue Lagoon B290065 pump head
- Original Blue Lagoon replacement pump head for the Dosatech dosing pump.
- Complete head assembly with integrated dosing hose and pump rotor.
- Designed for fast replacement to minimise downtime of the dosing system.
- Suitable for dosing liquid pool chemicals such as flocculant and sodium bicarbonate.
- Delivered ready to install on the existing Dosatech pump motor unit.
Function and application
In the Blue Lagoon Dosatech dosing pump, the pump head contains the rollers that press on the flexible hose and create the peristaltic pumping action.
During operation the hose is repeatedly compressed and relaxed, which causes normal wear over time. When the hose or the internal components
are worn, the pump can lose accuracy or stop dosing completely.
By replacing the complete pump head with the B290065 assembly, you restore the original dosing capacity and reliability of the Dosatech pump.
This spare part is suitable for installations where the motor and electronics are still in good condition and only the mechanical pump head
needs to be renewed.
Compatibility
- Designed specifically for the Blue Lagoon Dosatech dosing pump (article B210010N).
- Compatible with systems that use the standard Dosatech peristaltic head for pool water treatment.
- Can be combined with the separate replacement kit for dosing pump pool (B200030) when the suction and injection lines also need renewal.
Always check the model name Dosatech on the front of your dosing pump and the spare part reference B290065 in the technical documentation.
If these references match, this pump head is the correct replacement for your unit.
Installation guidelines
- Disconnect the power supply to the Dosatech dosing pump before starting any work.
- Remove the existing pump head by loosening the fixing screws or clips according to the manual.
- Carefully pull the old head away from the drive shaft and disconnect the dosing hose from the suction and injection lines.
- Position the new Blue Lagoon B290065 pump head on the motor unit and align it with the drive shaft.
- Reconnect the suction and injection hoses, then secure the head with the supplied screws or the original fasteners.
- Prime the pump and check for leaks or air bubbles before returning the system to normal operation.
Maintenance advice
- Inspect the pump head and dosing hose regularly for signs of wear, flattening or cracking.
- Replace the B290065 pump head at the intervals recommended in the Blue Lagoon Dosatech documentation, or sooner in heavy duty use.
- Check the suction strainer and injection fitting for blockages to maintain a stable flow.
- Protect the pump head against direct chemical spills and rinse the exterior if product is accidentally splashed on it.
Scheduled replacement of the Blue Lagoon B290065 pump head keeps the Dosatech dosing pump accurate and reliable, which supports stable water treatment
and consistent chemical dosing in the pool installation.
