what are the applications of the swimming pool pump Espa Silen 50M?

Recirculation and filtration of water in medium-sized pools. Ideal for pools of 45 m3 and 500 mm diameter filter.

The espa pool pumps are single-cell centrifugal pumps with built-in filtration elements, specially designed for pre-filtering and recirculation of water in swimming pools.

They are designed to work with clean water and a maximum temperature of 35°C.

Checks prior to the initial start-up of the pool pump:

Once the connections defined in the previous section have been made, unscrew the relevant filter cover and fill the pump pre-filter with water up to the lower level of the suction pipe.

• Check that the pump shaft rotates freely.
• Check that the mains voltage and frequency correspond to those stated on the nameplate of the pump.
• Replace the pre-filter cover and screw it back in place as required.
• Check that the direction of rotation of the motor corresponds to that indicated on the fan cover. On three-phase motors, if the direction of rotation is incorrect, reverse two power supply phases on the protection panel.
• If the motor does not start, try to find the fault by referring to the list of the most common faults and their possible solutions on the following pages.

NEVER RUN THE PUMP DRY.

Starting the pool pump Espa Silen 50M.

• Open all gate valves and energise the motor.
• Wait a reasonable time for the pipe to self-prime.
• Check the current draw and adjust the thermal relay accordingly.

Maintenance of the swimming pool pump Espa Silen 50M.

• Pool pumps do not require any specific maintenance. However, it is recommended to clean the pump filter periodically, empty the pump body during periods of low temperatures by means of the drain plug.
• If inactivity persists, it is advisable to empty the pump of water, clean it and replace the filter cover with vaseline on the rubber gasket, making sure that the room where it will be stored remains dry and ventilated.
• In the event of a fault, the user must not tamper with the pump. Contact an authorised technical service.
• When it is time to dispose of the pump, it does not contain any toxic or polluting material.
