As a desander and desilter manufacturer,we also make feeding centrifugal pumps for feeding the hydrocyclones.As required by clients,sometimes we offer centrifugal pumps with mechanical seals.
The advantages of mechanical seals centrifugal pump over compression packing or glands are:
 Desander Desilter Feeding Pump
1) Mechanical seals ensures sand pump almost zero or very little (as per the regulations) leakage of the fluid from the pump casing to the surroundings.
2) The mechanical seals pump can sustain high pressures of the fluids and highly corrosive fluids. There is always some leakage from the compressible packing and sometimes they tend to fail under the deteriorating effects of the chemicals, but such problems do not occur with the mechanical seals.
3) There is no friction between the moving parts of the mechanical seal so there is no extra power consumption by the centrifugal pump. Continue reading »

GN solids control produce almost the same thing with Fluids system hydrocyclones. GN ZQJ series desander and desilter can be compared with world famous brand solids control equipments, such as Derrick, Swaco, Fluids system, etc.
 desander
Fluid Systems Hydrocyclone
The Fluid Systems, Inc. desander units are the result of an intensive research and development program initiated in 1950.Designed by Krebs Engineers, eachhydrocyclone represents a product of advanced design, careful engineering,quality materials and finest workmanship.The interdependence of inlet, vortex and apex orifices are of prime importance to top performance, and for that reason,Krebs Cyclones are designed for easy interchangeability of a wide range of orifice sizes to assure superior results. The material of construction in Krebs Hydrolcyclones are a key to important economies.
GN ZQJ series desanderZQJ series desander is the second phase solids control equipment in well drilling, the general cones are 8”, 10”, and 12”, mainly separate 47~76μm particle out. According to customers’ treating capacity requirements, choose different quantity cones. GN also provide desander without under fluids shaker.
GN ZQJ series desilter
ZQJ series desilter is the third phase solids control equipments in well drilling mud system, the usual cones are 4”, 5”, and 6”. Used to separate 15~47μm particle out. According to clients’ treating capacity requirements choose different quantity cones.

Our “dredge slurry separation system” and ” waste mud treatment system” used together to process the highly polluted river.
we called ”dredge slurry separation system” as A, ” waste mud treatment system” as B.
 dredge slurry separation system
Work principle of the dredge slurry separation system & waste mud treatment system
A sucked the sludge and separate the solids from the sludge. A including shale shaker(the first phase solids control), desander(the second phase solids control), desilter(the third phase solids control), etc.
GN2000 Dredged Slurry Separation System including linear motion shale shaker 2sets,mud cleaner 4sets, sand pump 2sets,agitator 2sets,Automatic liquid-level control device 2sets, circulation tank 1sets, electric control system 1set, lighting system 3sets, walkway,stair,guard rail,valve, pipeline 1set, etc.
1 The solids from shale shaker(maybe including some junk) should be dumping or smashed to use for foundation soil.
2 The solids from desander will be through curing process, to used for foundation soil or building construction materials(such as Brick ). Continue reading »

Our esteemed clients inquiry for GNTJ60 Mud Cleaner & ZQJ300S desander, and would like to know more details about them.
GNTJ60 Mud Cleaner is the smallest mud cleaner in GNZJ&GNPJ series mud cleaner. Its treating capacity is less than 60m3/h(equal to 264GPM), it adopts 4pcs 4″ desilter cone and 1pc 8″ desander cone, it depends on the exact treating capacity you required. The cone number can be customized, for example,4″ desilter cones =12~15 m3/h, once you less a cone, the treating capacity will less 12~15 m3/h, so you can dicede by yourself. 
The material of GN mud cleaner:
Desilter Cones Material:100%PU
Vibrating Motor:Italy OLI
Connecting Bolts:SS304
Painting:Japan (Kansai Paint Co.,Ltd)
Electric components:SIEMENS
ZQJ300S desander is the largest desander in GN ZQJ series desander, its treating capacity is 240m3/h(equal to 1056GPM), it adopts 1~2pcs 12″ desander cone, 12″ cone =120m3/h, it means that if you choose one 12″ cone, the treating capacity of the desander is 120m3/h, if you choose 2pcs 12″ cone, the treating capacity is 240m3/h. It can be customized.
It can separate 47~76 μm particles, the screen area is 1.0m2. If there is no “S” in the model No., it means no under fluids shaker. Our Kuwait clients have bought 5 sets of desander and desilter but without under fluids shaker.

Description of Desander
The hydrocyclone desander is used to separate solids in some definite range, take 10’’ for example, it is used in 40-100 micron range. It contains a precise combination of angles, ratios, and materials proportions to optimize finer particle separation or directly to the screening equipment.
For optimum performance, the feed head may be produced by a gravity-feed system or centrifugal pump.

Desander and Desilter
Desander is the second class and the third class solid control equipment to treat the drilling fluid. According to the size of the cone diameter, it is divided into Desander and Desilter. Usually the cone diameter is more than 6″is called Desander, and used as the second-control equipment in drilling operation. We commonly used 8 “and 10″ cones desander to separate solid-phase particle size 47-76μm in the drilling fluids.
