Type HC

Qmax=600m3/h – Hmax=120m 

APPLICATION

HC 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 located horizontally at the axis while the delivery flange is located vertically upwards. The pump outer 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 centrifugal consisting of a gland seal fed with grease and of an additional expeller reducing the pressure on the packing. Version with mechanical seal is also available. The whole rotating assembly together with the bearing housing can be shifted along the axial direction without pump disassembly in order to adjust the sealing gap between the impeller and the front liner.

HC pumps can be made in a vertical version.

MATERIALS OF CONSTRUCTION

Wet end components are made of MTL-26 – wear resistant high chromium alloy cast steel.
