Type OŁ
Qmax=300m3/h – Hmax=18m
APPLICATION
OŁ pumps are designed to handle slurries containing high concentration of solids such as sand, gravel, stone, coal, slag, ores, clay, whitewash, tailings etc.
Typical application include:
Mines – in coal or ore processing plants
Mineral raw materials mines – for hydraulic transport of sand, gravel and stones
Power industry – for hydraulic disposal of slag and ash
Steelworks – for pumping water with scale
Cement plants – for pumping sand and raw materials
Sugar factories – for pumping industrial waste
DESIGN
Stationary, single-stage, centrifugal, horizontal slurry pumps with closed impellers. The suction flange is positioned horizontally at side of the pump while the delivery flange is located vertically upwards. The pump casing is protected from inside by replaceable wear resistant liners. The axial thrust is absorbed by a thrust roller bearing. The bearings are oil lubricated. The shaft is sealed by a stuffing box with a gland water led to the lantern ring. Stuffing box is located on the suction side of the pump. The entire rotating assembly can be shifted in axial direction in order to adjust the sealing gap between the impeller and the front liner.
The pumps can be powered directly via a coupling or via a v-belt transmission.
MATERIALS OF CONSTRUCTION
Wet end components are made of MTL-26 – wear resistant high chromium alloy cast steel.
