High hardness,anti-wear alloy cast iron

Sand Suction Pump:

Constructin of this pump is 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 degree. This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and abrasion resistance.

Sealing forms: Packing gland, expeller seal, mechanical seal.

Driving type: V belt drive, hydraulic coupling drive, fluid coupling drive, frequency conversion drive devices, thyrister speed regulation ect.

They are suitable for delivering slurries in mining, explosive sludge in metal melting, grudging in dredger and course of river, and other fields. Type TZGH pumps are of high head ones.


1) Cantilevered, horizontal, centrifugal, one stage, single casing gravel (sand) pump

2) High head, large capacity, high efficiency.

3) Good NPSH performance.

4) Widely application: they are designed for handling more abrasive with solids slurries in the river dredging, Sand reclamation, Sugar beet, explosive sludge in metal melting, grudging in dredger and course of river and other fields.

5) Long bearing life: The bearing assembly is with large diameter shaft and short overhang.

6) Wear resistant wet parts: the wet parts are made of Ni hard and high chromium abrasion resistance alloys. (more than 26% Chrome alloy).

7) Simple maintenance throat bush: the mating face of the throat bush is tapered, so the wear is reduced and removal is simple.

8) Easy adjustment of impeller: An impeller adjustment mechanism is provided below the bearing housing.

9) Centrifugal seal, mechanical seal and packing seal are available.

10) The pump can be directly matched with either motor or diesel engine

More specification:

It can be equipped with diesel engines or be equipped with motor driven directly. It has the advantages of working stability, little vibration, low noise and low hydraulic loss, high efficiency, low fuel consumption and small size, light weight, simple structure, easy maintenance.
