HL series Centrifugal Light Duty Slurry Pumps
Similar to the H slurry pumps, but designed for medium to lower slurry gravities and discharge heads. The HL series is offered fully lined with split outer casings.
HL Series slurry pumps maintain the ruggedness and slurry handling capacity of the H Series, but with a larger range of flow-rates and lower life-cycle costs. Higher efficiency impellers make the HL Series an important feature in any cost-conscious hydraulic process stream.
This series are widely used in industries, such as Ball mill discharge Rod mill discharge, Ni acid slurry, Coarse sand, Coarse tailings, Phosphate matrix, Minerals concentrate, Bottom/fly ash, Lime grinding, Oil sands, Mineral sands, Fine tailings, Phosphoric acid, Coal, Flotation, Process chemical, Pulp and paper, FGD, Wastewater
Liners – wide variety of metallurgic and elastomeric options (metal and elastomer interchangeable) – active engineered attachment mechanism to casing via threaded bolts as opposed to unreliable glue
Impeller – higher efficiency rates (up to 90+ %) – pump out vanes on rear and front (on closed impellers) reduce recirculation within pump, and aid in preventing seal contamination
Throat bush – wide variety of metallurgic and elastomeric options (metal and elastomer interchangeable) – adjustable via cotters to account for wear over time and increase efficiency
Expeller Seal(Centrifugal Seal) – Available with low flow water flush or zero flow (grease lubricated) options to provide exceptional sealing where water introduction to the seal is intolerable or limited.
Stuffing Box – Gland sealing with packing and lantern ring.
Bearing assembly - All bearings assembled with highest quality tapered roller bearings in controlled environments to prevent lubricant and housing contamination – oversized shaft diameters and reduced overhang in the wet end contribute to long life and reliability in the field
Pump Casing – Split-case design allows for ease of access and maintenance on wet end parts – cast ductile iron with exterior ribbing provides increased pressure ratings and reliable service over time
Frame Base – A very robust one-piece frame cradles the cartridge type bearing and shaft assembly. An external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller clearance.
