MATERIALS
Motor housing (Aluminium) Model B (Cast iron) Pressure cover (Aluminium additionally NBR rubberized) Model B (Cast iron) Motor jacket, suction stainer (Stainless steel/Aluminium) Model B (Stainless steel) Rotor shaft, screws (Stainless steel) Impeller – up to H 500/3,5 (Cast iron GG 25/EN-GJL-250) – from H 500/5,5 (Hard casting) – H 700 (Cast iron GG 25/EN-GJL-250) Pump housing (Cast iron GG 25/EN-GJL-250) Mechanical seals (Silicon carbide) Seal kit (Perbonane)
PUMPED LIQUID
Clear water or drainage water with abrasive (e.g. sand) solids. Max. liquid temperature: 40°C, short term up to 60°C.
MOTOR
Fully submersible, pressuretight, jacket cooled motor, oil-filled. Insulation class H. Motor protection IP 68. Cable connection chamber totally isolated from motor housing. Thermal sensors embedded in motor winding (types from 5,5D).
FEATURES
With their small diameter casing and central top discharge the pumps are the ideal solution for operation in narrow wells where conventional submersibIe pumps would be too large. The water jacket cooled motor with the top discharge protects the motor against overheating even during sip operation. Model B for aggressive liquids, e. g. seawater, alkaline solution.
IMPELLER
Impeller of the H700 series.
For optimum adaptation to the pump medium and operating conditions.
OPEN MULTI-CHANNEL IMPELLER
For dirty and muddy media with solids.
