Grundfos AP80 submersible pumps are a range of Vortex- and single-channel (1-channel) impeller pumps designed for transferring drainage- or wastewater. Due to the 80 mm spherical clearance, they are suitable for pumping liquids containing larger solids, such as fibres and textiles.

They are used for various applications in public and private sector, trade and industry. The compact design makes the pumps suitable for both temporary and permanent installation. The pumps can be installed on an auto-coupling system or on a ring stand to the bottom of the pit.

The pumps are made of wear-resistant materials, such as cast iron and stainless steel.

AP80 pumps are available with 1.3 and 2.6 kW motors. The pump housing has a DN 80 and 100 flange connection. The nominal outlet diameter is DN 80 and 100.

The pumps are designed for continuous (S1) operation. In this operating mode, the pump can operate continuously without being stopped for cooling.

Models are available with float switch control on request.

Thermal protection is enclosed in the motor winding and requires outside control through the signal wires of the power cable.

AP80 pumps have oil chamber seal probe for leakage control (only for models with 1.3 kW motors). It requires outside control through the signal wires of the power cable.
