To operate a mini dredger, two motor pumps are required.
One motor-pump for very dirty water, for pumping water-soil mixture.
The second motor pump is high-pressure clean water for loosening bottom sediments.
Different manufacturers of motor pumps have models for dirty water and high pressure motor pumps that can be used for hydraulic washing on a mini dredger.
The following combinations are possible:
Honda
Honda WT 40 Hose outlet with a diameter of 100 mm (4″)
Honda WH 15
Honda WT 30 Hose outlet with a diameter of 76 mm (3″)
Honda WH 15
For hydraulic washing, you can also use a motor pump Honda WH 20
Wacker Neuson
Wacker Neuson 4″ PTS4 Centrifugal Trash Pump Hose outlet with a diameter of 100 mm (4″)
Wacker Neuson Dewatering Pumps PG2A
Wacker Neuson 3″ PTS 3 Centrifugal Trash Pump Hose outlet with a diameter of 76 mm (3″)
But it is better to use another high-pressure motor pump
DAISHIN
DAISHIN SWT-100 Hose outlet with a diameter of 100 mm (4″) (TRASH PUMP)
DAISHIN SWT-80 Hose outlet with a diameter of 76 mm (3″) (TRASH PUMP)
DAISHIN SCH5050 (HIGH HEAD)

Do you already have a motor pump and you do not know if it can be used on a mini dredger?
