Electric pump

SUBMERSED ELECTRIC PUMP FOR SEWAGE BACKUP

Material:
tie-rods, handle, nuts and bolts, motor casing and shaft in stainless steel; cover, pump body and impeller in mechanic cast iron; mechanical seal in graphite and ceramic; asynchronous motor with short-circuit rotor in coolant bath mounted on ball bearings.

Application:
submersed electric pump with set-back or double-channel impeller for pumping of waste water, sewage backup and septic tanks; drainage of rainwater; pumping of liquids containing solids and filaments (with set-back impeller).

Use and maintenance:
under normal operating conditions, the electric pump does not  require  any  maintenance  operations.  In case of permanent installation, an annual inspection is recommended in which the liquid inlet is cleaned (and the metal filter, if any) of mud and debris and the wear conditions of the impeller are checked as well as the status of electric cable, handle and fastener.

SUBMERSED PUMP FOR CLEAR WATER

Material:
outer casing, handle, nuts and bolts, motor casing and shaft in stainless steel; pipe union, motor and central body cover in brass; impellers and diffusers in noryl® reinforced in fibreglass, certified for potable water; mechanical seal in graphite and ceramic with lubrication chamber; asynchronous motor with short-circuit rotor mounted on ball bearings.

Application:
submersed electric pump for pumping water from stormwater tanks and wells.

Use and maintenance:
under normal operating conditions, the electric pump does not require any maintenance operations. It is advisable to periodically check the current absorption and delivery pressure of the pump. A current absorption higher than the nominal value can be caused by abnormal mechanical friction in the motor or pump. A reduction in delivery pressure can be caused by wear in the hydraulic  components of the pump.
