The pump base forms the basic support part of the unit and transfers its weight evenly to the installation surface. The original design for the Niper 3 and Silen I models meets the precise dimensional tolerances of the manufacturer Espa.
A correctly seated base reduces operating noise and protects the bolted joints from excessive stress caused by vibrations. We recommend checking it during every annual pump inspection.
The base is made of durable plastic resistant to moisture and pool chemicals, so it retains its shape even after years of operation in a wet environment.
