Construction of this pump is one of single casing connected by means of clamp bands and wide wet-passage. The wet-parts are made of Ni-hard and high chromium abrasion-resistance alloys. The discharge direction of pump can be oriented in any direction of 360°.This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and abrasion resitance.

Type notation;   

 For example:

150/100D-G (orGH)   6-suction diameter(inch) 4-discharge diameter(inch)

D-frame form  G-gravel pump  GH-high-head of gravel pump

STRUCTURAL CHARACTERISTICS;

A horizontal, single-shell structure pump, flow components hardware nickel, chromium high abrasion resistant material and has good wear resistance, corrosion resistance and high reliability. Low NPSH must NPSHr.

 Matrix Road off circulation and can be used for large-particle abrasion materials continuous conveyor.

Drum structure bearing components, use high-capacity bearings design, use of lipid-lubricating bearings, lubricating oil used to adapt to different conditions.                              

Adjustable impeller and the clearance between the board to ensure efficient operation of the pump.

Seal a packing seal, seal and play impeller assembled mechanical seal, adapt to different conditions require.

Pump and drive straight for the choice of the drive, V-belt drive, hydraulic coupling drive, drive reducer.

Pump in the direction of the export of a 360-degree rotation installation location to accommodate different installation conditions at the scene.

SEALING FORMS;

1 Packing gland: For the suction or gravity condition. The pressure of sealing liquid should be 35Kpa higher than the discharge pressure of the seen in following table.

2 Expeller seal: In general for gravity condition the gravity head

should not be exceeded to 10% of the total head of the pump and the shaft power increase by 5% about.

APPLICATION;

1.Absorb the sand in the river, lake and sea.

2.Absorb the silt and sand in the river, lake, sea, reservoir, pound, electric power plant .

3.Absorb the slurry of stone processing plant.

4.Absorb the slurry in the deep well.
