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
