Construction

Submersible motor pump for vertical installation. Hydraulics in a sectional construction with radial impellers and an integrated non-return valve. The Housing parts are made of stainless steel and the impellers and diffuser are made of plastic. Encapsulated, oil-filled single-phase AC motor for direct start with self-lubricating bearings. The shaft is sealed by a mechanical seal. The motor housing, shaft, and coupling are made of stainless steel. The non-detachable connection cable must be extended to the required length on site and connected to the capacitor box. The capacitor box contains a start capacitor, a motor protection switch, and an on/off switch. It also has a connection cable with an attached plug (type CEE7/7). The capacitor box is not waterproof.
