Pump description

1. What is a sand pump?

 

G series sand dredging pump is a new type of single-stage single-suction cantilever horizontal centrifugal sludge pump researched & manufactured by our company, aiming at dredging and damming of the river and seas.

 

Strongly wear-resistant casting alloy iron, whose hardness is not less than 58HRC adoped for the casting, impeller, front liner and rear liner of wet parts. It throughout meets requirements of the dredge to dredging pumps.

 

2. What advantage of G sand pump?

 

Large drdging depth, high density of dredging mud, good NPSH and stronger suction lift ability
Strong through-put. The pump can persistently discharge gravel, high plastic soil lump and so on
3The pump can be directly matched with either motor or diesel engine
4Wide application. It can be used in various kinds of soil quality.
5Little hydraulic loss, high efficiency and low oil-consumption
6Little volume, light weight
7Steady operating, little vibration, low noise
8Simple & reliable construction, easily disassembly & assembly, convenient maintaining
9Reliable sealing without leakage
10Long operation life of parts, high reliability of whole set, long MTBF
11Obvious economic efficiency and energy-saving

 

3. What structure of G sand pump 

 

The structure of 4-20 inch type pumps are single-casing, which uses the mechanical sealing or stuffing sealing or mechanical stuffing compound sealing. According to the connection with the gear box, two structures can be offered: self-carrying bracket and pump-box assembly. The lubrication for the bracket is grease or thin oil.

The structure of 24-40 inch type pumps are double-casing, which adopts spiral sleeve L (shape) rubber sealing device that consists of three L sealing ring and one special thread shaft sleeve. It has self-carrying bracket. Lubrication is forced thin oil lubricating. The double-casing design can ensure the liner can work till it is worn out, and if the liner crack, water can not enter into the pump.
