CE Approved 2W. W Fuel Oil Twin Screw Pump

Model NO.: 2W. W6.9-96 Screw Suction Method: Double Suction Performance: Wearable Certification: CE, ISO Screw Material: 38CrMoAl Bush Material: Bronze Trademark: HOFFWELL Origin: Cn Screw Number: Multi Screw Pump Pump Shaft Position: Horizontal Application: Sewerage Treatment, Food, Chemical Pump Body Material: Cast Iron Ht200 Shaft Material: 45# Steel Seal: Mechanical Seal Specification: CE, SGS HS Code: 8413604090 Project Description
1, conveying liquid stationary, no pulse, no stirring, little vibration, low noise.
2, have very strong self-priming performance, heterogeneous mixing to lose, gas rate is not Higher than 80%, sand concent not higher than 500 G/M3.
3, the outer bearing structure, adopt independent lubrication, can transport all kinds of lubricity Medium.
4, the synchronous gear drive, two rotor between contact, even for a short time idle also just as Well.
5, pump body with heating jacket, can transport all kinds of clean or containing solid granule of low viscosity and high viscosity medium (general particle diameter less than 0.12-0.2 mm)
6, the correct selection of materials, and even can transport a lot of corrosive medium.
7, double suction type structure, there is no rotor axial force.
8, and end use of mechanical seal or bellows mechanical seal, with long life, less leakage, wide Application characteristics.

Working scope
1, max pressure: 4.0MPa
2, Capacity: 1~1000m3/h
3, temperature: -20~150 centigrade
4, medium viscosity: 1~3000mm2/s, lower speed: 106mm2/s

Application example 
1,Oil field:Used as the multiphase mixed transporting pump and crude oil transporting pump and the like which can transport oil,gas,water,tiny solid particullate. 
2,shipbuilding:Using as marine loading pump,ballast pump an sewage treatment pump , main machine lubricating pump and fuel Oil Pump. 
3,Petrochemical industry:Using as loading and transporting pump which can transport all kinds of resin,pigment , paraffinwax,paint,rinting ink,emulsoid,all kinds of oil crude oil,hesvy oil and the like. 
4,Power plant:Using as heavy oil,crude oil transporting pump,main machine lubricating pump. 
5,Food industry:Using as transporting pump which can transport alcohol,honey,syryp,juide,fixde oil,milk,slurry oil. 

Structure characteristics 
This kind of pump adotp double-suction structure , both ends of screw are in the same pressure cavity,axial force an be balanced automatically.The bearing of both ends adopt external installing,an being lubricated a lone by using lubricate,so it won't be influenced bu the medium.A couple of synchronous gears are uwed to drive the screws,so the screws surface can't touch at all,an there is a tiny chearance between the two screws. the impurity in the meditm can not fray the screws surface directly(escept scour) .
Except some less discharge ppumps (below the 2w.w 4.0),generally,internal safety valve will be installed on the pump body,when the discharge pressure is over the rated value,it will have certain protection function.There are two entrance-exit directions ,one is horizontally enter and horizontally exit;the other is horizontally enter and vertically upwards exit; the user can choose according to thir own demands.
