HKL series Submersible Screw centrifugal pumps


1.High Efficiency
Reduce power cost (connected horse power can now cost more than usd1000 per horse power)
2.Clog free operation
No blockage means minimum attention and minimum maintenance, except for periodic adjustments
3.Gentle Action
Prevents damage to delicate solids
4.Steep head-capacity curve
Minimizes interruptions in capacity, prevents motor overloads, and provides additional pressure to blow out plugs
5.Low NPSH requiremets
Hept to keep thick sludges and large solid moving as available suction head decreases. It also reduces installation costs.
6.Positive suction flow
Enables the pump to easily handle thick sludges
7.Externally adjustable liners
8.Abrasion-resistant construction
With 550 brinell, high chrome iron impeller and externally adjustable suction liner available.

Remarks: We have been OEM for many brands from Europe and USA
