Centrifugal Wear resistant power plant slurry pump

1. Paramters

2. Overview

NNT BRAND Type of NH series centrifugal slurry pumps are cantilevered,horizontal,slurry pumps.

1. They are designed for the handling highly abrasive, high density slurry in the metallurgical, mining, coal, power, building material and other industrial departments etc.

2. The pumps of this type also can be installed in multistage series.

3. The frame plates for type NH centrifugal slurry pumps have replaceable wear-resistant

metal liners or rubber liners.

4. The impellers are made of wear resistant chrome alloy or rubber.

5. The frame plate liner and impeller for HH pump are adoptable of wear-resistant metal only .

6. The shaft seals for type NH centrifugal slurry pumps can be adoptable of gland seal or expeller seal.

3. Structure

Single stage, single suction, overhang shaft, centrifugal, double-casing horizontal pump,wet ends are made of abrasive resistant hard metal or rubber.

Base - High strengthened base is connected with Frame Plate by bolts; The Adjusting Bolt under the Bearing Assembly realize easy adjustment to impeller clearance.

Bearing Assembly:

-High rigidity shaft to handle heavy duty work condition;

-Cartridge bearing assembly jointed with base by bolts;

-Grease Lube bearings fitted in sealed bearing housing, the two labyrinth on both ends prevent the grease from contamination.

Shaft Sleeve - Clearance fit between solid solution treated stainless steel shaft sleeve and shaft as well as the O-rings on both ends prevent the shaft from abrasion and erosion.

Casing - Made of Gray Iron or Ductile Iron, Ribs help casing to stand high pressure.

Impeller - Pump out vanes on both shrouds reduces recirculation and seal pressure.

Wet Ends - Impellers, liners, volutes made of High-Chrome alloy or rubber, both materials are interchangeable.

1). Cantilever, horizontal centrifugal slurry pump

2). Better wear-resistance and corrosive resistance

3). Frame plate for type pumps have replaceable wear-resistant metal ( high chrome alloy ) liners or rubber liners. Impeller material : high chrome alloy or Natural rubber .

4). In allowable pressure range, it can be used in series in stages, and allowable

maximum working pressure is 3.6Mpa.

5). Expeller seal, mechanical seal and packing seal are available .

6). The discharge branch can be positioned at interval of 45 degrees by request and oriented

to any eight positions to suit installations and applications.

7). To adapt to convey heavy abrasion, high concentration dreg , slurry pump's body is

used double-deck construction , in other words, being made of inside lining and outside shell.

For example: 6/4E-NH
