Brief Introduction :

We MAXWAY MACHINE COMPANY LTD (MMCL) is the first company that design and produce the hydraulic submersible dredge pump,

brand PUMPKING, in China since year 2008.
It is mainly used to suction sand / mud / clay / small rock from river, pond, shipping port, tailing, shallow sea, sewer and soft mud terrain.

It could be attached on excavator or hydraulic power pack to transport sand / mud / small rock to far place easily.
According to client’s hydraulic system and working requests, 4 to 16 inch output hydraulic submersible dredge pumps could be produced for you.

Working Principle:

Excavator hydraulic system or hydraulic power pack drives the hydraulic motors that installed in the dredge pump,

then hydraulic motors drive the pump impeller and cutter (cutters are used to sir the hard sand or mud) to rotate at high speed.

Pump suction slurry and discharge them to far place via discharge hoses.

Main Advantage Design:

Assembled famous brand hydraulic motor,

very durable and reliable working performance.

Quality warranty for 1 year.

Assembled top class hydraulic distribution valve .

It could help to protect the hydraulic motors that installed in

the main pump and cutters

Pump shaft, mechanical seals and bearings are installed in

oil chambers. So, our pump does NOT need any lubricating.

Users could save a lot of labor cost and time.

Our pump could keep working in 24 hours per day.

The pump casing / impeller / guard plates / agitator / side cutter

are made of Cr26 or Cr30 alloy with heat treatment .

More durable than stainless steel and common casting steel.

The side cutters (or center cutter) on pump could stir hard sand,

clay or mud to raise the working efficiency.

Our pump is installed mechanical seal (made by hard alloy).

Its working performance is better a lot than common seals,

and life time is longer.
