Lid Seal for Espa Silen Pump – Old Generation

The lid seal for the Espa Silen pump for the old generation of models is a precisely shaped sealing ring that prevents water leakage or air intake at the prefilter basket closure. A cracked or deformed seal causes loss of pump priming, noisy operation and reduced performance of the entire filtration circuit – its timely replacement quickly resolves this problem. The original dimensions ensure correct seating without the need for additional sealing agents. The material withstands chlorinated water, UV radiation and temperatures typical of outdoor pool operation. Replacement takes only a minute – simply unscrew the transparent prefilter lid, replace the seal and put the lid back.
