H700 – Submersible pumps for clear and drainage water

Wear resistant submersible pumps with jacket cooling

APPLICATION

HOMA H 500 and H 700 are wear resistant submersible pumps, designed for drainage of dirty water, pumping clear water or leakage water, H 500 also for water including abrasive solids. The pumps are used to pump surface water from building sites, wells, subways or tunnels, for lowering ground water, for irrigation, supply of industrial water, application on board ships etc.

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.
