shaft sleeve packing volute liner for slurry pump

Detailed description of lurry pumps

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, explosive sludge in metal melting, dredging 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) The frame plate for type AM pumps have replaceable wear-resistant metal liners or rubber liners. The impellers are made of wear-resistant metal or rubber.

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 shaft seals for type AM pumps may be adoptable of gland seal or expeller seal

11) The discharge branch can be positioned at interval of 45 degrees by request and oriented to any eight positions to suit installations and applications.

Main Features

A large percentage of duties allow the use of the ce ntrifugal seal which eliminates the need of sealing water.
Gland shaft seal
A packed gland type shaft seal is also available and can be fitted with a low flow or a full flow flush seal water arrangement.
Shaft and bearing assembly
A large diameter shaft with a short overhang minimizes deflection and vibration.Heavy-duty roller bearings are housed in a removable bearing cartridge.
Pump Base
A minimum number if through bolts hold the pump casing to the frame .A means of impeller adjustment is provided in a convenient position below the bearing housing.
Outer Casing

Split outer casing halves of cast or ductile iron contain the wear liners and provide high operation pressure capabilities.
Impeller
The impeller may be either moulded elastomer or hard metal.Deep side sealing vanes relieve seal pressure and minimize recirculation.

Cast-in impeller threads are better suited for slurries.
Interchangeable hard metal and moulded elastomer liners.
Mating faces in hard metal liners are tapered to allow positive alignment during assembly and allow components to be easily removed for replacement.
Hydraulic seal rings give positive sealing between mating faces.
