The submersible sewage Sidus pumps are designed to pump sewage and waste water, as well as other non- aggressive liquids with a density of up to 1250 kg/m3, with a hydrogen value рН within the range of 5...12, with a high content of solid particles having a dimension of up to 160 mm and long-fibred inclusions.
The said electric pump is not intended for operation in explosion-and-fire hazard premises.
|Range of capacities||8 - 2500 m3/h|
|Range of heads||7 - 80 m|
|Temperature of the liquid being handled||up to + 80 °С|
|Size of solid particles being handled||up to 160 mm|
|Rotational speed||750 - 3000 rpm|
|Degree of protection of the electric motor||IP68|
|Mode of operation||continuous|
|Diameter of delivery branch pipe||40 – 400 mm|
|Type of impellers||semi-open, channel (single-blade, multi-blade), free-vortex ones|
|Materials of impellers||grey cast-iron, stainless steel, duplex steel with 25% of chrome|
|Seal of the shaft||double end-face seal|
|Materials of seal friction pair||silicon carbide/silicon carbide|
The said electric pump is a monoblock consisting of the electric motor and centrifugal pump.
The motors are provided with dry winding with incorporated temperature protection sensors.
The construction design provides for various types of impellers: semi-open, channel (single-blade, multi-blade), free-vortex ones. Impellers have different material versions: grey cast iron, stainless steel, duplex steel with 25 % of chrome.
The tightness of the motor is effected by two end-face seals and the dividing oil chamber. Oil chamber is equipped with system of warning about leaks.
