Working Principle
Features
WETTED PARTS
IMPELLERS–Interchangeable metal and rubber impellers available. Pump out vanes on rear and front reduce recirculation within pump, which prevents seal contamination.
LINERS–Interchangeable metal and rubber liners available Easily replaceable liners are attached to casing by threaded bolts rather than unreliable glue.
THROATBUSH –Interchangeable metal and rubber throat bush– adjustable via cotters to account for wear over time and increase efficiency.
SEALS–GTEK offers a wide variety of seal options to suit any process requirements
EXPELLER (CENTRIFUGAL SEAL)–available with low flow water flush or zero flow (grease lubricated) options to provide exceptional sealing where water introduction to the seal is intolerable or limited.
STUFFING BOX–gland sealing with packing and lantern ring.
MECHANICAL SEALS
BEARING ASSEMBLY–Large shaft diameters and reduced overhang in the wet end contribute to long life and reliability in the field.
CASING–Split-case design allows for ease of access and maintenance on wet end parts. Cast ductile iron with exterior ribbing provides increased pressure ratings and reliable service over time.
BASE–A very robust one-piece frame cradles the cartridge type bearing and shaft assembly. An external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller clearance.
