ZG Sand Gravel Pump 20x18

Zidong ZG durable design coarse sand suction pumps are designed for continuously handling the most difficult higher abrasive slurries which contain too big solids to be pumps by a common slurry pump. The pump body(casing & impeller) made of 27% high chrome alloy, the ultra thick pump case let the pump anti-wear and need lowest maintenance cost.

Pump Size: 4-20inch

Capacity Range: 36-4320 m3/h

Head Range: 10- 80m

Speed Range: 200-1400rpm

Power Range: 60-1200kw


Overview


ZG(H) Series Sand Gravel Pump is horizontal single-casing gravel pump with wide channel to transfer sand, slurries or gravels with big particle size.

The wet parts are made of Ni-hard and high-Chrome alloys resistance material to ensure long service life. It has superior performance than common pumps in

dredging, sand mining, barge loading and mineral processing etc.

Features


1. Broad impeller path created by single casing and clamp bands connection;

2. Unique design to make maintenance and wet parts replacement convenient;

3. Dig deep advantage, good dig deep effect within 30 meters.
4.Using a variety of speed and modifications to make pump running under best condition. Long service life, high efficiency which can meet many poor transport conditions.
5. The discharge direction of pump can be oriented in any direction of 360°.
6. Driving type mainly have V belt drive, elastic coupling drive, gear reducer drive, hydraulic coupling drive, variable frequency driven etc.
ZG Sand Gravel Pump


It adopt international advanced technology, non-clogging design with big flow channel and 3-Vane high efficiency closed impeller. Large solid particles are allowed.

● Bearing assembly – a large diameter shaft with short overhang minimizes deflection & contributes to long bearing life.
● Casing – single casing be made of high-chrome alloy, provide long wear time.
● Impeller – 3 vanes impeller, processing larger solids easily. The impeller and casing are threaded connection,no need nuts. High efficiency and high head designs are also available.
● Cover plate – wear is reduced and maintenance simplified by the use of tapered mating faces to allow positive accurate alignment during assembly and simple removal.

● One-piece frame – a very robust one-piece frame cradles the cartridge type bearing and shaft assembly. An external impeller adjustment mechanism is provided for easy adjustment of impeller clearance
