16/14TU-G Heavy River Dredging Large Capacity High Chrome Alloy Anti-Wear Sand Gravel Pump

Product introduction:

Type G(or GH) gravel pumps are the series products introduced from Warman International Equipment Ltd. Gravel pumps are designed for continously handling the most difficult higher abrasive slurries which contain too big solids to be pumped by a common pump. Type GH pumps are of high head ones.

Main Features

1. Single stage, single case, metal liner, horizontal anti-abrasion centrifugal pump.

2. Advanced hydraulic model, CAD-aided design, high efficiency and remarkable energy-saving effect.
3. Strong flow capacity. The pump can pump gravel, high plastic clay lumps and so on.
4. Strong matching capacity. The diesel engine and the motor are both available.
5. Stable running, small vibration and low noise.
6. The whole machine has high reliability and remarkable economic benefits.

Impeller

The impeller generally has three vanes or five vanes and wide application range.It is made of wear-resistant high chromium alloy cast iron(hardness≥58HRC,impact toughness≥9J/cm2).The impeller is fixed on the pump shaft with double thread,and the thread tolerances are inspected according to the pitch diameter of thread.Disassembly rings are installed at the rear of the shaft sleeve to make maintenance eas

Volute casing

The volute casing is made of wear-resistant and compression-resistant alloy(hardness≥56HRC,impact toughness≥8J/cm2).Advanced smelting technology combined with casting process and heat treatment process guarantees smooth casting surfaces and reliable internal qualiyt.

The bulge test will be carried out after molding,and the test pressure is 2 times of the discharge pressure of the pump.If there no leakage after 20 minutes,strength and tightness,strength and tightness pressure test reports can be issued.

Liner plate

The liner plates are made of wear-resistant high chromium alloy cast iron(hardness≥56HRC,impact toughness≥8J/cm2).

Seals
1. Expeller (Centrifugal Seal) – no external sealing water required where applicable
2. Stuffing Box – flushed gland sealing with braided packing and a lantern ring
3. Mechanical Seals

Bearing Assembly
1. Cartridge-style bearing housing allows for removal from pump and assembly in controlled environment
2. Oversized shaft diameters and reduced overhang in the wet-end contribute to long life and reliability in the field
