<p>The protection device uses a protection sleeve (14) fitting around the electrical supply cable (12) fed to the pump head (10), with the protection sleeve secured to the pump head via a clamp (20,22). The electrical supply cable may move longitudinally relative to the protective sleeve, which is sufficiently flexible to allow the cable to be rolled up. A clamp sleeve for the supply cable can be fitted in the protective sleeve (16;28) at the end nearest the pump head, or at both ends.</p> |
