Construction Features
- Close-coupled, single-impeller centrifugal pump with axial suction and radial delivery.
- Treaded suction and delivery ports (Rp ISO 7).
- Compact construction; adapter for motor/pump coupling; the impeller is keyed directly to the motor shaft extension.
- Back pull-out design; no need to disconnect the pump body from the system pipes.
- All components in contact with pumped liquid are made of AISI 316L stainless steel
- AISI 316L stainless steel open impeller with four pressed vanes welded onto base disk.
- Impeller’s front wear surface consists of a study AISI 316L stainless steel plate welded onto the suction port.
- AISI 316L stainless steel pump body and seal housing disk, with no diffusers or cavities for easier
- cleaning and maintenance.
- Pump body tightened by 8 screws allowing rotation of the discharge head.
