♦ First choice for effluent treatment plants since there are no mechanical seals / glands. May run dry due to absence of shaft seals. Lesser parts result in low maintenance time and costs.
Expeller :
♦ Solid injection moulded polypropylene expeller prevents liquid from going further up channelizing it through the outlet of the overflow chamber.
Backplate :
♦ The back plate is thick walled solid injection moulded from polypropylene.
Volute Casing :
♦ Top centerline discharge, self venting volute casing formed of thick injection moulded polypropylene.
Impeller :
♦ Impellers are precision moulded, light in weight, a semi open construction with large, contoured flow passages for maximum handling of the liquid.
Bearing Frame :
♦ Heavy cast iron construction. To accommodate vertical flange type motor & for a wall hung installation.
Ball Bearing :
♦ Single. Double row ball bearing is shouldered & locked on a shaft with locknut and washer, and in bearing housing to carry radially and any unbalanced thrust load.
Shaft :
♦ The shaft is made of En Steel protected with a polypropylene sleeve dose not come in contact with process media.
Overflow Chamber :
♦ Large injection moulded polypropylene chamber guide’s excess liquid back to the sump eliminating the need for a shaft seal.
