Single-stage centrifugal pump as baseplate pump in accordance with ISO 2858, with axial suction ports and radial pressure ports for installation on a base. Pump with support foot and flanged bearing bracket, coupling, coupling guard and motor mounted to same baseplate.
IEC motor with 3 PTC thermistor sensors. Shaft sealing with bidirectional bellows mechanical seal. Stainless steel housing, stainless steel shaft, stainless steel impeller. Stainless steel as standard for all hydraulic components in contact with fluid.
Coupling variants:
- Spacer coupling (standard)
- Elastic coupling (variant P5, at a reduced price)
Impeller variants (for an additional charge):
- BZ
- Stainless steel/Duplex
Shaft Seal variants
- Single (standard)
- Cartridge (single/double)
- Stuffing box packing
NOTICE
The elastic coupling does not contain a spacer.
The spacer coupling is an elastic coupling with a spacer. The spacer reduces maintenance costs and no further motor alignment is necessary when replacing the mechanical seal.
